[jira] [Created] (DERBY-5295) Make Derby self-tune the preallocated
ranges for identity columns and sequences.
Make Derby self-tune the preallocated ranges for identity columns and sequences.
--------------------------------------------------------------------------------
Key: DERBY-5295
URL: https://issues.apache.org/jira/browse/DERBY-5295
Project: Derby
Issue Type: Improvement
Components: SQL
Reporter: Rick Hillegas
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.
