Adding a column to the database table

Add a column to the supported database table to synchronize an existing field from a Pulsar topic.

  1. On a database node, use ALTER TABLE to add the column to the table.

  2. Confirm that the schema change has been pushed to all nodes using nodetool describecluster.

    Data synchronization may fail if the schema change is inconsistent across the entire cluster.
  3. In the DataStax Apache Pulsar™ Connector configuration file, add the field-to-column definition. See Mapping pulsar topics to database tables.
