Previously, last_completed_partition was updated during batch flushes while
the partition was still being processed. This caused resume to skip partitions
that were only partially completed.
Now, last_completed_partition is only updated AFTER all consolidation groups
in a partition have been processed and the final buffer flush is complete.
