    Description

      Greater throughput can be achieved by configuring how many values Derby preallocates for sequences and identity columns. It may be possible for Derby to self-tune the length of these preallocated ranges rather than hardcoding a one-size-fits-all length. The logic would go into the SequenceRange class. For more discussion of the issues, see DERBY-4437.
