SingleStore - CData Cloud

Overview

CData Cloud offers access to SingleStore across several standard services and protocols, in a cloud-hosted solution. Any application that can connect to a SQL Server database can connect to SingleStore through CData Cloud.

CData Cloud allows you to standardize and configure connections to SingleStore as though it were any other OData endpoint or standard SQL Server.

Key Features

  • Full SQL Support: SingleStore appears as standard relational databases, allowing you to perform operations - Filter, Group, Join, etc. - using standard SQL, regardless of whether these operations are supported by the underlying API.
  • CRUD Support: Both read and write operations are supported, restricted only by security settings that you can configure in Cloud or downstream in the source itself.
  • Secure Access: The administrator can create users and define their access to specific databases and read-only operations or grant full read & write privileges.
  • Comprehensive Data Model & Dynamic Discovery: CData Cloud provides comprehensive access to all of the data exposed in the underlying data source, including full access to dynamic data and easily searchable metadata.

CData Cloud

Getting Started

This page provides a guide to Establishing a Connection to SingleStore in CData Cloud, as well as information on the available resources, and a reference to the available connection properties.

Connecting to SingleStore

Establishing a Connection shows how to authenticate to SingleStore and configure any necessary connection properties to create a database in CData Cloud

Accessing Data from CData Cloud Services

Accessing data from SingleStore through the available standard services and CData Cloud administration is documented in further details in the CData Cloud Documentation.

CData Cloud

Establishing a Connection

Connect to SingleStore by selecting the corresponding icon in the Database tab. Required properties are listed under Settings. The Advanced tab lists connection properties that are not typically required.

Connecting to SingleStore

The following connection properties are required in order to connect to data.

  • Server: The host name or IP of the server hosting the SingleStore database.
  • Port: The port of the server hosting the SingleStore database.

You can also optionally set the following:

  • Database: The default database to connect to when connecting to the SingleStore Server. If this is not set, tables from all databases will be returned.

Standard Authentication

To authenticate using standard authentication, set the following:

  • User: The user which will be used to authenticate with the SingleStore server.
  • Password: The password which will be used to authenticate with the SingleStore server.

Connect Using Integrated Security

As an alternative to providing the standard username and password, you can authenticate trusted users to the server via Windows Authentication.

SSL Authentication

You can leverage SSL authentication to connect to SingleStore data via a secure session. Configure the following connection properties to connect to data:

  • SSLClientCert: Set this to the name of the certificate store for the client certificate. Used in the case of 2-way SSL, where truststore and keystore are kept on both the client and server machines.
  • SSLClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
  • SSLClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
  • SSLClientCertType:; The certificate type of the client store.
  • SSLServerCert: The certificate to be accepted from the server.

SSH Authentication

Using SSH, you can securely login to a remote machine. To access SingleStore data via SSH, configure the following connection properties:

  • SSHClientCert: Set this to the name of the certificate store for the client certificate.
  • SSHClientCertPassword: If a client certificate store is password-protected, set this value to the store's password.
  • SSHClientCertSubject: The subject of the TLS/SSL client certificate. Used to locate the certificate in the store.
  • SSHClientCertType: The certificate type of the client store.
  • SSHPassword: The password that you use to authenticate with the SSH server.
  • SSHPort: The port used for SSH operations.
  • SSHServer: The SSH authentication server you are trying to authenticate against.
  • SSHServerFingerPrint: The SSH Server fingerprint used for verification of the host you are connecting to.
  • SSHUser: Set this to the username that you use to authenticate with the SSH server.

CData Cloud

SSL Configuration

Customizing the SSL Configuration

To enable TLS, set UseSSL to True.

With this configuration, the Cloud attempts to negotiate TLS with the server. The server certificate is validated against the default system trusted certificate store. You can override how the certificate gets validated using the SSLServerCert connection property.

To specify another certificate, see the SSLServerCert connection property.

Client SSL Certificates

The SingleStore Cloud also supports setting client certificates. Set the following to connect using a client certificate.

  • SSLClientCert: The name of the certificate store for the client certificate.
  • SSLClientCertType: The type of key store containing the TLS/SSL client certificate.
  • SSLClientCertPassword: The password for the TLS/SSL client certificate.
  • SSLClientCertSubject: The subject of the TLS/SSL client certificate.

CData Cloud

Firewall and Proxy

Connecting Through a Firewall or Proxy

Set the following properties:

  • To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
  • To tunnel the connection, set FirewallType to TUNNEL.
  • To authenticate, specify FirewallUser and FirewallPassword.
  • To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

Azure Authentication

This section provides a complete list of the Azure Authentication properties you can configure in the connection string for this provider.


PropertyDescription
AzureTenantIdentifies the SingleStore tenant being used to access data. Accepts either the tenant's domain name (for example, contoso.onmicrosoft.com ) or its directory (tenant) ID.
CData Cloud

AzureTenant

Identifies the SingleStore tenant being used to access data. Accepts either the tenant's domain name (for example, contoso.onmicrosoft.com ) or its directory (tenant) ID.

Data Type

string

Default Value

""

Remarks

A tenant is a digital container for your organization's users and resources, managed through Microsoft Entra ID (formerly Azure AD). Each tenant is associated with a unique directory ID, and often with a custom domain (for example, microsoft.com or contoso.onmicrosoft.com).

To find the directory (tenant) ID in the Microsoft Entra Admin Center, navigate to Microsoft Entra ID > Properties and copy the value labeled "Directory (tenant) ID".

This property is required in the following cases:

  • When AuthScheme is set to AzureServicePrincipal or AzureServicePrincipalCert
  • When AuthScheme is AzureAD and the user account belongs to multiple tenants

You can provide the tenant value in one of two formats:

  • A domain name (for example, contoso.onmicrosoft.com)
  • A directory (tenant) ID in GUID format (for example, c9d7b8e4-1234-4f90-bc1a-2a28e0f9e9e0)

Specifying the tenant explicitly ensures that the authentication request is routed to the correct directory, which is especially important when a user belongs to multiple tenants or when using service principal–based authentication.

If this value is omitted when required, authentication may fail or connect to the wrong tenant. This can result in errors such as unauthorized or resource not found.

CData Cloud

OAuth

This section provides a complete list of the OAuth properties you can configure in the connection string for this provider.


PropertyDescription
OAuthClientIdSpecifies the client ID (also known as the consumer key) assigned to your custom OAuth application. This ID is required to identify the application to the OAuth authorization server during authentication.
OAuthClientSecretSpecifies the client secret assigned to your custom OAuth application. This confidential value is used to authenticate the application to the OAuth authorization server. (Custom OAuth applications only.).
CData Cloud

OAuthClientId

Specifies the client ID (also known as the consumer key) assigned to your custom OAuth application. This ID is required to identify the application to the OAuth authorization server during authentication.

Data Type

string

Default Value

""

Remarks

This property is required in two cases:

  • When using a custom OAuth application, such as in web-based authentication flows, service-based authentication, or certificate-based flows that require application registration.
  • If the driver does not provide embedded OAuth credentials.

(When the driver provides embedded OAuth credentials, this value may already be provided by the Cloud and thus not require manual entry.)

OAuthClientId is generally used alongside other OAuth-related properties such as OAuthClientSecret and OAuthSettingsLocation when configuring an authenticated connection.

OAuthClientId is one of the key connection parameters that need to be set before users can authenticate via OAuth. You can usually find this value in your identity provider’s application registration settings. Look for a field labeled Client ID, Application ID, or Consumer Key.

While the client ID is not considered a confidential value like a client secret, it is still part of your application's identity and should be handled carefully. Avoid exposing it in public repositories or shared configuration files.

For more information on how this property is used when configuring a connection, see Establishing a Connection.

CData Cloud

OAuthClientSecret

Specifies the client secret assigned to your custom OAuth application. This confidential value is used to authenticate the application to the OAuth authorization server. (Custom OAuth applications only.).

Data Type

string

Default Value

""

Remarks

This property (sometimes called the application secret or consumer secret) is required when using a custom OAuth application in any flow that requires secure client authentication, such as web-based OAuth, service-based connections, or certificate-based authorization flows. It is not required when using an embedded OAuth application.

The client secret is used during the token exchange step of the OAuth flow, when the driver requests an access token from the authorization server. If this value is missing or incorrect, authentication fails with either an invalid_client or an unauthorized_client error.

OAuthClientSecret is one of the key connection parameters that need to be set before users can authenticate via OAuth. You can obtain this value from your identity provider when registering the OAuth application.

Notes:

  • This value should be stored securely and never exposed in public repositories, scripts, or unsecured environments.
  • Client secrets may also expire after a set period. Be sure to monitor expiration dates and rotate secrets as needed to maintain uninterrupted access.

For more information on how this property is used when configuring a connection, see Establishing a Connection

CData Cloud

SSLServerCert

Specifies the certificate to be accepted from the server when connecting using TLS/SSL.

Data Type

string

Default Value

""

Remarks

If you are using a TLS/SSL connection, use this property to specify the TLS/SSL certificate to be accepted from the server. If you specify a value for this property, all other certificates that are not trusted by the machine are rejected.

This property can take the following forms:

Description Example
A full PEM Certificate (example shortened for brevity) -----BEGIN CERTIFICATE-----
MIIChTCCAe4CAQAwDQYJKoZIhv......Qw==
-----END CERTIFICATE-----
A path to a local file containing the certificate C:\cert.cer

Data Type

string

Default Value

"Password"

Remarks

  • None: No authentication is performed. The current SSHUser value is ignored, and the connection is logged in as anonymous.
  • Password: The Cloud uses the values of SSHUser and SSHPassword to authenticate the user.
  • Public_Key: The Cloud uses the values of SSHUser and SSHClientCert to authenticate the user. SSHClientCert must have a private key available for this authentication method to succeed.

CData Cloud

SSHClientCert

A certificate to be used for authenticating the SSHUser.

Data Type

string

Default Value

""

Remarks

SSHClientCert must contain a valid private key in order to use public key authentication. A public key is optional, if one is not included then the Cloud generates it from the private key. The Cloud sends the public key to the server and the connection is allowed if the user has authorized the public key.

The SSHClientCertType field specifies the type of the key store specified by SSHClientCert. If the store is password protected, specify the password in SSHClientCertPassword.

Some types of key stores are containers which may include multiple keys. By default the Cloud will select the first key in the store, but you can specify a specific key using SSHClientCertSubject.

CData Cloud

SSHClientCertPassword

The password of the SSHClientCert key if it has one.

Data Type

string

Default Value

""

Remarks

This property is required for SSH tunneling when using certificate-based authentication. If the SSH certificate is in a password-protected key store, provide the password using this property to access the certificate.

CData Cloud

SSHClientCertSubject

The subject of the SSH client certificate.

Data Type

string

Default Value

"*"

Remarks

When loading a certificate the subject is used to locate the certificate in the store.

If an exact match is not found, the store is searched for subjects containing the value of the property.

If a match is still not found, the property is set to an empty string, and no certificate is selected.

The special value "*" picks the first certificate in the certificate store.

The certificate subject is a comma separated list of distinguished name fields and values. For instance "CN=www.server.com, OU=test, C=US, [email protected]". Common fields and their meanings are displayed below.

FieldMeaning
CNCommon Name. This is commonly a host name like www.server.com.

CData Cloud

MaxRows

Specifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.

Data Type

int

Default Value

-1

Remarks

The default value for this property, -1, means that no row limit is enforced unless the query explicitly includes a LIMIT clause. (When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting.)

Setting MaxRows to a whole number greater than 0 ensures that queries do not return excessively large result sets by default.

This property is useful for optimizing performance and preventing excessive resource consumption when executing queries that could otherwise return very large datasets.

CData Cloud

Timeout

The value in seconds until the connection timeout error is thrown.

Data Type

int

Default Value

30

Remarks

If the Timeout property is set to 0, the default of 30 seconds will be used instead.

If Timeout expires and the operation is not yet complete, the Cloud throws an exception.

CData Cloud

ZeroDatesToNull

Whether or not to return Date and DateTime values consisting of all zeros as NULL.

Data Type

bool

Default Value

true

Remarks

Whether or not to return Date and DateTime values consisting of all zeros as NULL. A value of all zeros indicates an invalid Date or DateTime value in SingleStore. Retrieving such a value may cause parsing errors unless you set this property to True.

a) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free copyright license to reproduce, prepare derivative works of, publicly display, publicly perform, distribute and sublicense the Contribution of such Contributor, if any, and such derivative works, in source code and object code form.

b) Subject to the terms of this Agreement, each Contributor hereby grants Recipient a non-exclusive, worldwide, royalty-free patent license under Licensed Patents to make, use, sell, offer to sell, import and otherwise transfer the Contribution of such Contributor, if any, in source code and object code form. This patent license shall apply to the combination of the Contribution and the Program if, at the time the Contribution is added by the Contributor, such addition of the Contribution causes such combination to be covered by the Licensed Patents. The patent license shall not apply to any other combinations which include the Contribution. No hardware per se is licensed hereunder.

c) Recipient understands that although each Contributor grants the licenses to its Contributions set forth herein, no assurances are provided by any Contributor that the Program does not infringe the patent or other intellectual property rights of any other entity. Each Contributor disclaims any liability to Recipient for claims brought by any other entity based on infringement of intellectual property rights or otherwise. As a condition to exercising the rights and licenses granted hereunder, each Recipient hereby assumes sole responsibility to secure any other intellectual property rights needed, if any. For example, if a third party patent license is required to allow Recipient to distribute the Program, it is Recipient's responsibility to acquire that license before distributing the Program.

d) Each Contributor represents that to its knowledge it has sufficient copyright rights in its Contribution, if any, to grant the copyright license set forth in this Agreement.

3. REQUIREMENTS

A Contributor may choose to distribute the Program in object code form under its own license agreement, provided that:

a) it complies with the terms and conditions of this Agreement; and

b) its license agreement:

i) effectively disclaims on behalf of all Contributors all warranties and conditions, express and implied, including warranties or conditions of title and non-infringement, and implied warranties or conditions of merchantability and fitness for a particular purpose;

ii) effectively excludes on behalf of all Contributors all liability for damages, including direct, indirect, special, incidental and consequential damages, such as lost profits;

iii) states that any provisions which differ from this Agreement are offered by that Contributor alone and not by any other party; and

iv) states that source code for the Program is available from such Contributor, and informs licensees how to obtain it in a reasonable manner on or through a medium customarily used for software exchange.

When the Program is made available in source code form:

a) it must be made available under this Agreement; and

b) a copy of this Agreement must be included with each copy of the Program.

Contributors may not remove or alter any copyright notices contained within the Program.

Each Contributor must identify itself as the originator of its Contribution, if any, in a manner that reasonably allows subsequent Recipients to identify the originator of the Contribution.

4. COMMERCIAL DISTRIBUTION

Commercial distributors of software may accept certain responsibilities with respect to end users, business partners and the like. While this license is intended to facilitate the commercial use of the Program, the Contributor who includes the Program in a commercial product offering should do so in a manner which does not create potential liability for other Contributors. Therefore, if a Contributor includes the Program in a commercial product offering, such Contributor ("Commercial Contributor") hereby agrees to defend and indemnify every other Contributor ("Indemnified Contributor") against any losses, damages and costs (collectively "Losses") arising from claims, lawsuits and other legal actions brought by a third party against the Indemnified Contributor to the extent caused by the acts or omissions of such Commercial Contributor in connection with its distribution of the Program in a commercial product offering. The obligations in this section do not apply to any claims or Losses relating to any actual or alleged intellectual property infringement. In order to qualify, an Indemnified Contributor must: a) promptly notify the Commercial Contributor in writing of such claim, and b) allow the Commercial Contributor to control, and cooperate with the Commercial Contributor in, the defense and any related settlement negotiations. The Indemnified Contributor may participate in any such claim at its own expense.

For example, a Contributor might include the Program in a commercial product offering, Product X. That Contributor is then a Commercial Contributor. If that Commercial Contributor then makes performance claims, or offers warranties related to Product X, those performance claims and warranties are such Commercial Contributor's responsibility alone. Under this section, the Commercial Contributor would have to defend claims against the other Contributors related to those performance claims and warranties, and if a court requires any other Contributor to pay any damages as a result, the Commercial Contributor must pay those damages.

5. NO WARRANTY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Each Recipient is solely responsible for determining the appropriateness of using and distributing the Program and assumes all risks associated with its exercise of rights under this Agreement, including but not limited to the risks and costs of program errors, compliance with applicable laws, damage to or loss of data, programs or equipment, and unavailability or interruption of operations.

6. DISCLAIMER OF LIABILITY

EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

7. GENERAL

If any provision of this Agreement is invalid or unenforceable under applicable law, it shall not affect the validity or enforceability of the remainder of the terms of this Agreement, and without further action by the parties hereto, such provision shall be reformed to the minimum extent necessary to make such provision valid and enforceable.

If Recipient institutes patent litigation against a Contributor with respect to a patent applicable to software (including a cross-claim or counterclaim in a lawsuit), then any patent licenses granted by that Contributor to such Recipient under this Agreement shall terminate as of the date such litigation is filed. In addition, if Recipient institutes patent litigation against any entity (including a cross-claim or counterclaim in a lawsuit) alleging that the Program itself (excluding combinations of the Program with other software or hardware) infringes such Recipient's patent(s), then such Recipient's rights granted under Section 2(b) shall terminate as of the date such litigation is filed.

All Recipient's rights under this Agreement shall terminate if it fails to comply with any of the material terms or conditions of this Agreement and does not cure such failure in a reasonable period of time after becoming aware of such noncompliance. If all Recipient's rights under this Agreement terminate, Recipient agrees to cease use and distribution of the Program as soon as reasonably practicable. However, Recipient's obligations under this Agreement and any licenses granted by Recipient relating to the Program shall continue and survive.

Everyone is permitted to copy and distribute copies of this Agreement, but in order to avoid inconsistency the Agreement is copyrighted and may only be modified in the following manner. The Agreement Steward reserves the right to publish new versions (including revisions) of this Agreement from time to time. No one other than the Agreement Steward has the right to modify this Agreement. IBM is the initial Agreement Steward. IBM may assign the responsibility to serve as the Agreement Steward to a suitable separate entity. Each new version of the Agreement will be given a distinguishing version number. The Program (including Contributions) may always be distributed subject to the version of the Agreement under which it was received. In addition, after a new version of the Agreement is published, Contributor may elect to distribute the Program (including its Contributions) under the new version. Except as expressly stated in Sections 2(a) and 2(b) above, Recipient receives no rights or licenses to the intellectual property of any Contributor under this Agreement, whether expressly, by implication, estoppel or otherwise. All rights in the Program not expressly granted under this Agreement are reserved.

This Agreement is governed by the laws of the State of New York and the intellectual property laws of the United States of America. No party to this Agreement will bring a legal action under this Agreement more than one year after the cause of action arose. Each party waives its rights to a jury trial in any resulting litigation.
