 Note that you only need to set the parameters that are required for the source database type. For example, you don't set `replication_slot` when taking CSV as the source.
 
+**Note** - `--src_filter` switch can be used as a namespace filter for source and accepts a regex. For e.g., if you want to filter one or more tables from a collection, you can specify them as `--src_filter="table1|table2|table3"`
