About the Custom CData Connector

With the Custom CData Connector, you can use a CDATA JDBC driver to ingest data from a SQL database or data warehouse.

Note

The Custom CData connector requires a JAR file from Incorta. Custom CData connectors may not have been verified or tested by Incorta. The JAR download is only available from Incorta Support and may require additional licensing. The Custom CData connector exposes various properties of the related CDATA JDBC driver for an external data source. You can review the CDATA JDBC driver documentation at Drivers & Data Connectors.

The Custom CDATA connector requires the deployment of a JAR file to the Incorta Node hosts of the Analytics Service and the Loader Service. A systems administrator with root access to the host can deploy the JAR file. A CMC Administrator can restart the Incorta cluster.

The Custom CData connector supports the following Incorta specific functionality:

Feature	Supported
Chunking	✔
Data Agent
Encryption at Ingest
Incremental Load	✔
Load Filter	✔
Multi-Source	✔
OAuth	✔
Performance Optimized	✔
Single-Source	✔
Spark Extraction
Webhook Callbacks	✔

Deploy the JAR file

The Custom CData Connector requires a JAR file for the related JDBC driver. Here is an example for Snowflake:

cdata.jdbc.snowflake.jar

Note

For the Driver class name, refer to CData JDBC Driver Documentation

To use the Custom CData connector, a System Administrator with root access will need to copy the JDBC driver JAR file of the database to each Incorta Node in an Incorta cluster. A CMC Administrator will need to restart the Analytics and Loader Services in the cluster.

Here are the steps to copy the JAR file to standalone Incorta cluster:

Contact Incorta Support and download the Customer CData connector driver JAR file.
Secure copy the cdata.jdbc.xyz.jar file to the host of the Analytics Service, Loader Service, and Cluster Management Console. Here is an example using scp:
```
INCORTA_NODE_HOST=100.101.102.103
INCORTA_NODE_HOST_PEM_FILE="host_key.pem"
INCORTA_NODE_HOST_USER="incorta"
CUSTOM_JDBC_JAR_FILE="cdata.jdbc.xyz.jar"

cd ~/Downloads
scp -i ~/.ssh/${INCORTA_NODE_HOST_PEM_FILE}  ${CUSTOM_JDBC_JAR_FILE} ${INCORTA_NODE_HOST_USER}@${INCORTA_NODE_HOST}:/tmp/
```
Note
If the Analytics Service, Loader Service, and Cluster Management Console all run on the same host, you only need to secure copy the file once.

Secure shell into the host

ssh -i ~/.ssh/${INCORTA_NODE_HOST_PEM_FILE} ${INCORTA_NODE_HOST_USER}@${INCORTA_NODE_HOST}

For the Analytics Service and Loader Service hosts, copy the JAR file to the /IncortaNode/extensions/connectors/cdata directory.
```
INCORTA_INSTALLATION_PATH=/home/incorta/IncortaAnalytics
CUSTOM_JDBC_JAR_FILE="cdata.jdbc.xyz.jar"
cp /tmp/${CUSTOM_JDBC_JAR_FILE} $INCORTA_INSTALLATION_PATH/IncortaNode/extensions/connectors/cdata/${CUSTOM_JDBC_JAR_FILE}
```
Note
If the Analytics Service and Loader Service both run on the same Incorta Node, the services share the same extensions directory and you need to only copy the file once.

For the Cluster Management Console host, copy the JAR file to the /cmc/extensions/connectors/cdata directory.

INCORTA_INSTALLATION_PATH=/home/incorta/IncortaAnalytics
CUSTOM_JDBC_JAR_FILE="cdata.jdbc.xyz.jar"
cp /tmp/${CUSTOM_JDBC_JAR_FILE} $INCORTA_INSTALLATION_PATH/cmc/extensions/connectors/cdata/${CUSTOM_JDBC_JAR_FILE}

Restart the Analytics and Loader Services

Here are the steps to restart the Analytics and Loader Services in an Incorta Cluster from the Cluster Management Console (CMC).

As the CMC Administrator, sign in to the CMC.
In the Navigation bar, select Clusters.
In the cluster list, select a Cluster name.
Select the Details tab, if not already selected.
In the footer, select Restart.

Steps to connect a database

To connect a database and Incorta, here are the high level steps, tools, and procedures:

Create an external data source
Create a physical schema with the Schema Designer
Load the physical schema
Explore the physical schema

Create an external data source

Here are the steps to create a external data source with the Custom CData connector:

Sign in to the Incorta Direct Data Platform™.
In the Navigation bar, select Data.
In the Action bar, select + New → Add Data Source.
In the Choose a Data Source dialog, in Custom, select Custom CData.
In the New Data Source dialog, specify the applicable connector properties.
To test, select Test Connection.
Select Ok to save your changes.

Custom CData connector properties

Here are the properties for the Custom CData connector:

Property	Control	Description
Data Source Name	text box	Enter the name of the data source
Driver Class	text box	Enter the driver class for the database. For example, the Snowflake driver name is `cdata.jdbc.xyz.XYZDriver`. To find the drive name, refer to the "Establishing a Connection" article in the CData JDBC Driver for XYZ documentation.
Connection String	text box	Enter the jdbc connection string.
Show Catalogs	toggle	Enable to list any data catalogs

To save your changes, select Done in the Action bar.

Custom CData table data source properties

For a physical schema table in Incorta, you can define the following Custom CData specific data source properties as follows:

Property	Control	Description
Type	drop down list	Default is SQL Database
Data Source	drop down list	Select the Custom CData external data source
Incremental	toggle	Enable the incremental load configuration for the physical schema table
Fetch Size	text box	Used for performance improvement, fetch size defines the number of records that will be retrieved from the database in each batch until all records are retrieved. The default is 5000.
Query	text box	Enter the SQL query to retrieve data from the Custom CData database table. This is a SELECT statement for a SQL query. You must specify a FROM clause. You need to know the Table Name. A file name will serve as a table name.
Update Query	text box	Enable Incremental to configure this property. Enter the SQL query to retrieve data updates from the Custom CData database table.
