Motivation

1.Improve readability

When I execute flink run $FLINK_HOME/lib/paimon-flink-action-0.9.0.jar mysql_sync_table --help, Poorly readable prompts are output.We need to improve this problem.
Several other actions have the same problem:

mysql_sync_table
mysql_sync_database

postgres_sync_table

kafka_sync_table
kafka_sync_database

mongodb_sync_table
mongodb_sync_database

pulsar_sync_table
pulsar_sync_database

2. Remove duplicate prompts from postgres_sync_table

https://github.com/apache/paimon/blob/master/paimon-flink/paimon-flink-cdc/src/main/java/org/apache/paimon/flink/action/cdc/postgres/PostgresSyncTableActionFactory.java#L56-L57

Solution

We can add prompt for cdc action to improving the output information.The desired look is as follows:

mysql_sync_table

mysql_sync_database

postgres_sync_table

kafka_sync_table

kafka_sync_database

mongodb_sync_table

mongodb_sync_database

pulsar_sync_table

pulsar_sync_database
