Neo4j Connector for CData Sync

Overview

The CData Sync App provides a straightforward way to continuously pipeline your Neo4j data to any database, data lake, or data warehouse, making it easily available for Analytics, Reporting, AI, and Machine Learning.

The Neo4j connector can be used from the CData Sync application to pull data from Neo4j and move it to any of the supported destinations.

Neo4j Version Support

The Sync App leverages the Neo4j HTTP API. The Sync App supports self-managed instances of Neo4j version 4.2 and above. Cloud Neo4j instances like those of AuraDB and AuraDS, which only support connections via Bolt protocol, are not supported.

Data Model

Overview

This section covers how the Sync App exposes your Neo4j graph database, and provides more information on executing SQL to Neo4j APIs.

Key Features

  • The Sync App models Neo4j graph node labels and relationships as relational views, allowing you to write SQL to query Neo4j data.
  • Stored procedures allow you to execute operations to Neo4j.
  • Live connectivity to these objects means any changes to your Neo4j account are immediately reflected when using the Sync App.

Modeling Node Graphs

Modeling Node Graphs details how node labels and relationships are exposed as views, as well as how properties are surfaced as columns.

Node and Relationship Filtering

The Sync App supports filtering which node labels and relationships are modeled as views. See Filtering Nodes and Relationships for more information.

Neo4j Connector for CData Sync

FirewallType

Specifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.

Remarks

A proxy-based firewall (or proxy firewall) is a network security device that acts as an intermediary between user requests and the resources they access. The proxy accepts the request of an authenticated user, tunnels through the firewall, and transmits the request to the appropriate server.

Because the proxy evaluates and transfers data backets on behalf of the requesting users, the users never connect directly with the servers, only with the proxy.

Note: By default, the Sync App connects to the system proxy. To disable this behavior and connect to one of the following proxy types, set ProxyAutoDetect to false.

The following table provides port number information for each of the supported protocols.

Protocol Default Port Description
TUNNEL 80 The port where the Sync App opens a connection to Neo4j. Traffic flows back and forth via the proxy at this location.
SOCKS4 1080 The port where the Sync App opens a connection to Neo4j. SOCKS 4 then passes theFirewallUser value to the proxy, which determines whether the connection request should be granted.
SOCKS5 1080 The port where the Sync App sends data to Neo4j. If the SOCKS 5 proxy requires authentication, set FirewallUser and FirewallPassword to credentials the proxy recognizes.

To connect to HTTP proxies, use ProxyServer and ProxyPort. To authenticate to HTTP proxies, use ProxyAuthScheme, ProxyUser, and ProxyPassword.

Specifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server.

Remarks

When this connection property is set to True, the Sync App checks your system proxy settings for existing proxy server configurations (no need to manually supply proxy server details).

This connection property takes precedence over other proxy settings. Set to False if you want to manually configure the Sync App to connect to a specific proxy server.

To connect to an HTTP proxy, see ProxyServer. For other proxies, such as SOCKS or tunneling, see FirewallType.

Neo4j Connector for CData Sync

ProxyServer

The hostname or IP address of the proxy server that you want to route HTTP traffic through.

Remarks

The Sync App only routes HTTP traffic through the proxy server specified in this connection property when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead routes HTTP traffic through the proxy server specified in your system proxy settings.

Neo4j Connector for CData Sync

ProxyPort

The TCP port on your specified proxy server (set in the ProxyServer connection property) that has been reserved for routing HTTP traffic to and from the client.

Remarks

The Sync App only routes HTTP traffic through the proxy server port specified in this connection property when ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead routes HTTP traffic through the proxy server port specified in your system proxy settings.

For other proxy types, see FirewallType.

Neo4j Connector for CData Sync

ProxyAuthScheme

Specifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property.

Remarks

The authentication type can be one of the following:

  • BASIC: The Sync App performs HTTP BASIC authentication.
  • DIGEST: The Sync App performs HTTP DIGEST authentication.
  • NTLM: The Sync App retrieves an NTLM token.
  • NEGOTIATE: The Sync App retrieves an NTLM or Kerberos token based on the applicable protocol for authentication.
  • NONE: Set this when the ProxyServer does not require authentication.

For all values other than "NONE", you must also set the ProxyUser and ProxyPassword connection properties.

If you need to use another authentication type, such as SOCKS 5 authentication, see FirewallType.

Neo4j Connector for CData Sync

ProxyUser

The username of a user account registered with the proxy server specified in the ProxyServer connection property.

Remarks

The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.

After selecting one of the available authentication types in ProxyAuthScheme, set this property as follows:

ProxyAuthScheme Value Value to set for ProxyUser
BASIC The user name of a user registered with the proxy server.
DIGEST The user name of a user registered with the proxy server.
NEGOTIATE The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user.
NTLM The username of a Windows user who is a valid user in the domain or trusted domain that the proxy server is part of, in the format user@domain or domain\user.
NONE Do not set the ProxyPassword connection property.

The Sync App only uses this username if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead uses the username specified in your system proxy settings.

Neo4j Connector for CData Sync

ProxyPassword

The password associated with the user specified in the ProxyUser connection property.

Remarks

The ProxyUser and ProxyPassword connection properties are used to connect and authenticate against the HTTP proxy specified in ProxyServer.

NTLM The password associated with the Windows user account specified in ProxyUser.
NONE Do not set the ProxyPassword connection property.

For SOCKS 5 authentication or tunneling, see FirewallType.

The Sync App only uses this password if ProxyAutoDetect is set to False. If ProxyAutoDetect is set to True, which is the default, the Sync App instead uses the password specified in your system proxy settings.

Neo4j Connector for CData Sync

ProxySSLType

The SSL type to use when connecting to the proxy server specified in the ProxyServer connection property.

Remarks

This property determines when to use SSL for the connection to the HTTP proxy specified by ProxyServer. You can set this connection property to the following values :

AUTODefault setting. If ProxyServer is set to an HTTPS URL, the Sync App uses the TUNNEL option. If ProxyServer is set to an HTTP URL, the component uses the NEVER option.
ALWAYSThe connection is always SSL enabled.
NEVERThe connection is not SSL enabled.
TUNNELThe connection is made through a tunneling proxy. The proxy server opens a connection to the remote host and traffic flows back and forth through the proxy.

Neo4j Connector for CData Sync

ProxyExceptions

A semicolon separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property.

Remarks

The ProxyServer is used for all addresses, except for addresses defined in this property. Use semicolons to separate entries.

Note that the Sync App uses the system proxy settings by default, without further configuration needed. If you want to explicitly configure proxy exceptions for this connection, set ProxyAutoDetect to False.

Neo4j Connector for CData Sync

Logging

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


PropertyDescription
LogModulesSpecifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.

LogModules

Specifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.

Remarks

This property lets you customize the log file content by specifying the logging modules to include. Logging modules categorize logged information into distinct areas, such as query execution, metadata, or SSL communication. Each module is represented by a four-character code, with some requiring a trailing space for three-letter names.

For example, EXEC logs query execution, and INFO logs general provider messages. To include multiple modules, separate their names with semicolons as follows: INFO;EXEC;SSL.

The Verbosity connection property takes precedence over the module-based filtering specified by this property. Only log entries that meet the verbosity level and belong to the specified modules are logged. Leave this property blank to include all available modules in the log file.

For a complete list of available modules and detailed guidance on configuring logging, refer to the Advanced Logging section in Logging.

Neo4j Connector for CData Sync

Schema

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

Location

Specifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.

Remarks

The Location property is only needed if you want to either customize definitions (for example, change a column name, ignore a column, etc.) or extend the data model with new tables, views, or stored procedures.

If left unspecified, the default location is %APPDATA%\\CData\\Neo4j Data Provider\\Schema, where %APPDATA% is set to the user's configuration directory:

Platform %APPDATA%
Windows The value of the APPDATA environment variable
Linux ~/.config

Neo4j Connector for CData Sync

BrowsableSchemas

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

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.

Neo4j Connector for CData Sync

Tables

Optional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .

Remarks

Listing all available tables from some databases can take extra time, thus degrading performance. Providing a list of tables in the connection string saves time and improves performance.

If there are lots of tables available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those tables. To do this, specify the tables you want in a comma-separated list. Each table should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Tables=TableA,[TableB/WithSlash],WithCatalog.WithSchema.`TableC With Space`.

Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each table you want to view by its fully qualified name. This avoids ambiguity between tables that may exist in multiple catalogs or schemas.

Neo4j Connector for CData Sync

Views

Optional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .

Remarks

Listing all available views from some databases can take extra time, thus degrading performance. Providing a list of views in the connection string saves time and improves performance.

If there are lots of views available and you already know which ones you want to work with, you can use this property to restrict your viewing to only those views. To do this, specify the views you want in a comma-separated list. Each view should be a valid SQL identifier with any special characters escaped using square brackets, double-quotes or backticks. For example, Views=ViewA,[ViewB/WithSlash],WithCatalog.WithSchema.`ViewC With Space`.

Note: If you are connecting to a data source with multiple schemas or catalogs, you must specify each view you want to examine by its fully qualified name. This avoids ambiguity between views that may exist in multiple catalogs or schemas.

Neo4j Connector for CData Sync

Miscellaneous

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


PropertyDescription
DetachDeleteA boolean value that controls whether the provider uses DETACH DELETE automatically when executing DELETE query.
MaxRowsSpecifies the maximum rows returned for queries without aggregation or GROUP BY.
NodeFilterA Cypher node label matching expression. The provider exposes all node labels from the matched nodes as views.
OtherSpecifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties.
PagesizeSpecifies the maximum number of results to return from Neo4j, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases.
PseudoColumnsSpecifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.
QueryPassthroughThis option passes the query to the Neo4j server as is.
RelationshipDestinationFilterThe type(s) of labels that must be present on the destination nodes of single-hop relationships that the provider will expose as views.
RelationshipSourceFilterThe node labels that must be present on the source nodes of single-hop relationships, which the provider will expose as views.
RelationshipTypeFilterThe relationship type(s) of single-hop relationships that the driver will expose as views.
RowScanDepthThe maximum number of rows to scan to look for the columns available in a table.
TimeoutSpecifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.
UserDefinedViewsSpecifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file.
Neo4j Connector for CData Sync

DetachDelete

A boolean value that controls whether the provider uses DETACH DELETE automatically when executing DELETE query.

Remarks

Nodes in Neo4j cannot be deleted if attached to any edge. By setting this property to 'true', the Sync App will automatically adjust a DELETE query to include a DETACH clause, putting the node into a deletable state before attempting operation.

Neo4j Connector for CData Sync

MaxRows

Specifies the maximum rows returned for queries without aggregation or GROUP BY.

Remarks

This property sets an upper limit on the number of rows the Sync App returns for queries that do not include aggregation or GROUP BY clauses. This limit ensures that queries do not return excessively large result sets by default.

When a query includes a LIMIT clause, the value specified in the query takes precedence over the MaxRows setting. If MaxRows is set to "-1", no row limit is enforced unless a LIMIT clause is explicitly included in the query.

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

Neo4j Connector for CData Sync

NodeFilter

A Cypher node label matching expression. The provider exposes all node labels from the matched nodes as views.

Remarks

By default, the Sync App will expose all labels from all nodes as views. By setting this property to a valid Cypher node label matching expression, the Sync App exposes all node labels from the matched nodes as views.

Neo4j Connector for CData Sync

Other

Specifies additional hidden properties for specific use cases. These are not required for typical provider functionality. Use a semicolon-separated list to define multiple properties.

Remarks

This property allows advanced users to configure hidden properties for specialized scenarios. These settings are not required for normal use cases but can address unique requirements or provide additional functionality. Multiple properties can be defined in a semicolon-separated list.

Note: It is strongly recommended to set these properties only when advised by the support team to address specific scenarios or issues.

Specify multiple properties in a semicolon-separated list.

Integration and Formatting

DefaultColumnSizeSets the default length of string fields when the data source does not provide column length in the metadata. The default value is 2000.
ConvertDateTimeToGMTDetermines whether to convert date-time values to GMT, instead of the local time of the machine.
RecordToFile=filenameRecords the underlying socket data transfer to the specified file.

Neo4j Connector for CData Sync

Pagesize

Specifies the maximum number of results to return from Neo4j, per page. This setting overrides the default page size set by the datasource, which is optimized for most use cases.

Remarks

You may want to adjust the default pagesize to optimize results for a particular object or service endpoint you are querying. Be aware that increasing the page size may improve performance, but it could also result in higher memory consumption per page.

Neo4j Connector for CData Sync

PseudoColumns

Specifies the pseudocolumns to expose as table columns. Use the format 'TableName=ColumnName;TableName=ColumnName'. The default is an empty string, which disables this property.

Remarks

This property allows you to define which pseudocolumns the Sync App exposes as table columns.

To specify individual pseudocolumns, use the following format: "Table1=Column1;Table1=Column2;Table2=Column3"

To include all pseudocolumns for all tables use: "*=*"

RelationshipDestinationFilter

The type(s) of labels that must be present on the destination nodes of single-hop relationships that the provider will expose as views.

Remarks

By default, the Sync App will expose all single-hop relationships as views. By setting this property to a valid Cypher node label matching expression, the Sync App will only expose the single-hop relationships where the destination node has the specified set of labels.

RelationshipSourceFilter

The node labels that must be present on the source nodes of single-hop relationships, which the provider will expose as views.

Remarks

By default, the Sync App will expose all single-hop relationships as views. By setting this property to a valid Cypher node label matching expression, the Sync App will only expose the single-hop relationships where the source node has the specified set of labels.

RelationshipTypeFilter

The relationship type(s) of single-hop relationships that the driver will expose as views.

Remarks

By default, the driver will expose all single-hop relationships as views. By setting this property to a valid, Cypher relationship type matching expression, the driver will only expose the single-hop relationships where the relationship type is part of the set of specified types.

RowScanDepth

The maximum number of rows to scan to look for the columns available in a table.

Remarks

The columns in a table must be determined by scanning table rows. This value determines the maximum number of rows that will be scanned.

Setting a high value may decrease performance. Setting a low value may prevent the data type from being determined properly, especially when there is null data.

Timeout

Specifies the maximum time, in seconds, that the provider waits for a server response before throwing a timeout error. The default is 60 seconds. Set to 0 to disable the timeout.

Remarks

This property controls the maximum time, in seconds, that the Sync App waits for an operation to complete before canceling it. If the timeout period expires before the operation finishes, the Sync App cancels the operation and throws an exception.

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.

Setting this property to 0 disables the timeout, allowing 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. Use this property cautiously to avoid long-running operations that could degrade performance or result in unresponsive behavior.

UserDefinedViews

Specifies a filepath to a JSON configuration file defining custom views. The provider automatically detects and uses the views specified in this file.

Remarks

This property allows you to define and manage custom views through a JSON-formatted configuration file called UserDefinedViews.json. These views are automatically recognized by the Sync App and enable you to execute custom SQL queries as if they were standard database views. The JSON file defines each view as a root element with a child element called "query", which contains the SQL query for the view. For example:


{
	"MyView": {
		"query": "SELECT * FROM ProductCategory WHERE MyColumn = 'value'"
	},
	"MyView2": {
		"query": "SELECT * FROM MyTable WHERE Id IN (1,2,3)"
	}
}

You can define multiple views in a single file and specify the filepath using this property. For example: UserDefinedViews=C:\Path\To\UserDefinedViews.json. When you use this property, only the specified views are seen by the Sync App.

Refer to User Defined Views for more information.
