Greenplum - CData Cloud

Overview

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

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

Key Features

  • Full SQL Support: Greenplum 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 Greenplum in CData Cloud, as well as information on the available resources, and a reference to the available connection properties.

Connecting to Greenplum

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

Accessing Data from CData Cloud Services

Accessing data from Greenplum 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 Greenplum 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 Greenplum

To connect to Greenplum, set the Server, Port (the default port is 5432), and Database connection properties and set the User and Password you want to use to authenticate to the server. If the Database property is not specified, the Cloud connects to the user's default database (it is the same name as the user).

Authenticating to Greenplum

The CData Cloud supports the md5, password, Kerberos and SASL (particulary, SCRAM-SHA-256) authentication methods.

The specific authentication method is setup in the pg_hba.conf file on the Greenplum Server. You can find instructions about authentication setup on the Greenplum Server here. The md5, password and SASL authentication methods do not require additional setup by the CData Cloud.

Kerberos

The Greenplum Server initiates authentication with the Kerberos Server when the CData Cloud attempts a connection. You need to setup Kerberos on the Greenplum Server to activate this authentication method. After you have Kerberos authentication setup on the Greenplum Server, see Using Kerberos for details on how to authenticate with Kerberos by the Cloud.

CData Cloud

Using Kerberos

Kerberos

Authenticating to Greenplum via Kerberos requires you to define authentication properties and to choose how Kerberos should retrieve authentication tickets.

Retrieve Kerberos Tickets

Kerberos tickets are used to authenticate the requester's identity. The use of tickets instead of formal logins/passwords eliminates the need to store passwords locally or send them over a network. Users are reauthenticated (tickets are refreshed) whenever they log in at their local computer or enter kinit USER at the command prompt.

The Cloud provides three ways to retrieve the required Kerberos ticket, depending on whether or not the KRB5CCNAME and/or KerberosKeytabFile variables exist in your environment.

MIT Kerberos Credential Cache File

This option enables you to use the MIT Kerberos Ticket Manager or kinit command to get tickets. With this option there is no need to set the User or Password connection properties.

This option requires that KRB5CCNAME has been created in your system.

To enable ticket retrieval via MIT Kerberos Credential Cache Files:

  1. Ensure that the KRB5CCNAME variable is present in your environment.
  2. Set KRB5CCNAME to a path that points to your credential cache file. (For example, C:\krb_cache\krb5cc_0 or /tmp/krb5cc_0.) The credential cache file is created when you use the MIT Kerberos Ticket Manager to generate your ticket.
  3. To obtain a ticket:
    1. Open the MIT Kerberos Ticket Manager application.
    2. Click Get Ticket.
    3. Enter your principal name and password.
    4. Click OK.

    If the ticket is successfully obtained, the ticket information appears in Kerberos Ticket Manager and is stored in the credential cache file.

The Cloud uses the cache file to obtain the Kerberos ticket to connect to Greenplum.

Note: If you would prefer not to edit KRB5CCNAME, you can use the KerberosTicketCache property to set the file path manually. After this is set, the Cloud uses the specified cache file to obtain the Kerberos ticket to connect to Greenplum.

Keytab File

If your environment lacks the KRB5CCNAME environment variable, you can retrieve a Kerberos ticket using a Keytab File.

To use this method, set the User property to the desired username, and set the KerberosKeytabFile property to a file path pointing to the keytab file associated with the user.

User and Password

If your environment lacks the KRB5CCNAME environment variable and the KerberosKeytabFile property has not been set, you can retrieve a ticket using a user and password combination.

To use this method, set the User and Password properties to the user/password combination that you use to authenticate with Greenplum.

Enabling Cross-Realm Authentication

More complex Kerberos environments can require cross-realm authentication where multiple realms and KDC servers are used. For example, they might use one realm/KDC for user authentication, and another realm/KDC for obtaining the service ticket.

To enable this kind of cross-realm authentication, set the KerberosRealm and KerberosKDC properties to the values required for user authentication. Also, set the KerberosServiceRealm and KerberosServiceKDC properties to the values required to obtain the service ticket.

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 Greenplum 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.

CData Cloud

None, Password, Public_Key

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.

false

Remarks

By default the Cloud will attempt to connect directly to Greenplum. When this option is enabled, the Cloud will instead establish an SSH connection with the SSHServer and tunnel the connection to Greenplum through it.

CData Cloud

Logging

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


PropertyDescription
VerbositySpecifies the verbosity level of the log file, which controls the amount of detail logged. Supported values range from 1 to 5.
CData Cloud

Verbosity

Specifies the verbosity level of the log file, which controls the amount of detail logged. Supported values range from 1 to 5.

Data Type

string

Default Value

"1"

Remarks

This property defines the level of detail the Cloud includes in the log file. Higher verbosity levels increase the detail of the logged information, but may also result in larger log files and slower performance due to the additional data being captured.

The default verbosity level is 1, which is recommended for regular operation. Higher verbosity levels are primarily intended for debugging purposes. For more information on each level, refer to Logging.

When combined with the LogModules property, Verbosity can refine logging to specific categories of information.

CData Cloud

Schema

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


PropertyDescription
BrowsableSchemasOptional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
CData Cloud

BrowsableSchemas

Optional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .

Data Type

string

Default Value

""

Remarks

Listing all available database schemas can take extra time, thus degrading performance. Providing a list of schemas in the connection string saves time and improves performance.

CData Cloud

Miscellaneous

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


PropertyDescription
AllowPreparedStatementPrepare a query statement before its execution.
FetchResultSetMetadataThis field sets whether the provider retrieves metadata pertaining to the schema and table name for resultset columns returned by the server.
MaxRowsSpecifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
SupportUnboundedColumnsWhen this property is set, the provider reports Int32.MaxValue as the size of the columns of data type 'bytea' and 'text'.
TimeoutSpecifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.
CData Cloud

AllowPreparedStatement

Prepare a query statement before its execution.

Data Type

bool

Default Value

true

Remarks

If the AllowPreparedStatement property is set to false, statements are parsed each time they are executed. Setting this property to false can be useful if you are executing many different queries only once.

If you are executing the same query repeatedly, you will generally see better performance by leaving this property at the default, true. Preparing the query avoids recompiling the same query over and over. However, prepared statements also require the Cloud to keep the connection active and open while the statement is prepared.

CData Cloud

FetchResultSetMetadata

This field sets whether the provider retrieves metadata pertaining to the schema and table name for resultset columns returned by the server.

Data Type

bool

Default Value

false

Remarks

By default, the Cloud will not request that the server provides detailed information about resultset columns like the table name or schema name. It requires issuing additional metadata queries via Cloud , and it may affect query performance essentially in some scenarios. Consider setting this property to True when you need such detailed descriptive information for the resultset columns.

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

SupportUnboundedColumns

When this property is set, the provider reports Int32.MaxValue as the size of the columns of data type 'bytea' and 'text'.

Data Type

bool

Default Value

true

Remarks

When false, columns of data type 'text' will report a size of DefaultColumnSize.

CData Cloud

Timeout

Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error.

Data Type

int

Default Value

30

Remarks

The timeout applies to each individual communication with the server rather than the entire query or operation. For example, a query could continue running beyond 60 seconds if each paging call completes within the timeout limit.

Timeout is set to 60 seconds by default. To disable timeouts, set this property to 0.

Disabling the timeout allows operations to run indefinitely until they succeed or fail due to other conditions such as server-side timeouts, network interruptions, or resource limits on the server.

Note: Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.

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.

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.
