> The secondary connection factory is used for schema generation, and for value
> generation operations. Under normal circumstances 2 connections should be
> sufficient, however, we have found in HIVE-28839 that connection starvation
> may still happen. (in that case due to a datanucleus bug)
> We should make the "objectstore-secondary" pool size configurable. This is
> needed at least until a final fix is not available for HIVE-28839, but
> probably it is good to have on the long run if we find other edge cases too.
