Removing a Table Column from the mapping specification
Remove a supported database table column.
-
Remove the field to column mapping from the configuration. See Mapping pulsar topics to database tables.
-
On a database node, use the ALTER TABLE to remove the column from the table.
You can only remove non-PRIMARY KEY columns. -
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 DataStax cluster.
