CouchDB in managed blockchain

I just had a conversation with AWS support team. and they only supports leveldb in ManagedBlockchain.
They do have a feature request for the couchDB. so hopefully they do support sooner than later

Now Amazon Hyperledger fabric supports node configuration in both LevelDB and CouchDB to save state of ledger at nodes. https://docs.aws.amazon.com/managed-blockchain/latest/APIReference/API_NodeConfiguration.html
