In stream processing, specifying the consumer-id for each table does not take effect when performing multiple table joins.

I can't see the consumer-id for tables like order_line in the system tables.

Research direction

Start by reproducing the multiple-table join in stream processing with Paimon 0.8 and Flink 1.17.2, then inspect the system tables to compare consumer-id values for each joined table, including order_line. Done means every table-specific consumer-id is visible and effective during the join.
