[feature](cdc) Support merging multiple databases with the same schema into a single Doris table during synchronization #375

Closed vinlee19 closed 4 months ago

vinlee19 commented 5 months ago

Proposed changes

if some tables in different databases have the same name, their schemas will be merged and their records will be synchronized into one Doris table. Otherwise, each table's records will be synchronized to a corresponding Doris table, and the Doris table will be named to 'databaseName_tableName' to avoid potential name conflict.
