Crawling strategyJDBC

The Blindata Agent does not include this driver: download the vendor JDBC driver and copy the .jar into the agent drivers folder, as described in Add JDBC drivers. Driver properties can be added under Advanced settings in the connection wizard.

Prerequisites & permissions

  • A Blindata Agent installed with network access to Apache Cassandra.
  • The vendor JDBC driver installed on the agent (see Add JDBC drivers).
  • A role with DESCRIBE permission on the keyspaces (access to system_schema).

Set up metadata crawling

  1. Create the connection to Apache Cassandra on the agent (see Connection settings) and use Test to verify it.
  2. Create or open the system that represents Apache Cassandra in the catalog and link it to the connection.
  3. In the CRAWLING tab add a crawling job with strategy JDBC.
  4. Run a TEST to check the number of extracted objects, then RUN or schedule the job.

The job options and the column aliases of every extraction query are described in the Generic JDBC reference.
