Hi Sharath,
You can use {"source": ..., "target": ..., "create_target": true,
"create_target_params": {"partitioned": true}, ...} to create
partitioned target dbs.
The option was there since version 2.2.0
https://docs.couchdb.org/en/stable/whatsnew/2.2.html?highlight=create_target_params#features
but unfortunately it was not documented yet.
Cheers,
-Nick
