  || In-memory back end || [https://issues.apache.org/jira/browse/DERBY-646 DERBY-646] || Rick || yes || 1) Verified that in-memory db leaves no disk footprint if you set the derby.stream properties appropriately 2) Verified that VFMemoryStorageFactory.purgeDatabase( ) removes an in-memory database (primer updated). 3) Verified that you can backup an in-memory db using SYSCS_UTIL.SYSCS_BACKUP_DATABASE, remove the database from memory, then recreate it using the createFrom URL attribute 4) I increased the heap size to 512m and then began filling up a table by doubling its size with insert...select statements. I did not notice any performance difference across various page cache sizes: 2000, 1000, 500, 250, 125, and 60. ||
