During the replication of a table from an Aurora Postgres database in AWS source to a Snowflake database in AWS target, the data appears to replicate properly, but the DDL does not come through. Apply Changes Processing is turned on to allow DDL changes to come through, but there is no indication that Qlik Replicate sees the DDL at all. Permissions and authorizations are set correctly.
Qlik Replicate - Any Version
AWS Aurora Cloud for PostgreSQL
Verify your PostgreSQL database's session_replication_role setting. If it is currently set to replica, set it to either origin or local.
The session_replication_role setting is used to enable or disable triggers. By default, tables are created with all triggers enabled, which means that they fire with the default setting "session_replication_role = origin". When it is set to "replica", it disables the firing of triggers.
Qlik Replicate uses a Stored Procedure called attrep_intercept_ddl to help capture the DDL.
