rDDATASETbe3c5da2bb44: Delay the unsubscribe to the end of handle_messages
Summary

to prevent some possible race condition leading to kafka errors like:

rd_kafka_assignment_partition_stopped: Assertion `rktp->rktp_started' failed

This could occur when, at the time of unsubscribing from a partition,
another partition is also depleted. Since the unsubscription consist in
resubscribing to all partitions except unsubscribes ones, we could try
to subscribe to such a depleted parition, leading to the error message
listed above.

Depends on D7462.

    Add support for limited row numbers in ORC files
    
    Make it possible to specify a maximum number of rows a table can store
    in a single ORC file. The limit can only be set on main tables for now

    directory_entry).
    
    This can be set by configuration only (no extra cli options).
