proper implementation of custom persistence - "c-" messages remaining in the db after delivery

[gs-harris]

We have implemented sqlite3 db user persistence.

We have observed that after messages are delivered/published the PERSISTENCE_COMMAND_KEY variety of the messages are left stacking up in the sqlite3 db; ie. "c-5",

Is this intended? Should the client application remove these messages from functionality in the callback MQTTAsync_deliveryComplete?

Many thanks!

sorry it was my mis-understanding, no problems.
