I was looking at
derby and the FAQ says in Memory version has not been completed, but to check
with list.. It also said this about six months ago :) Just
wondering if anything is being done on it...
Seems that derby in
my environment takes about 3 times as long as HSQL to startup and import my
starting data, and I assume this is due to difference in mem/disk
operations. Oddly derby is WAY faster on all join queries than
hsql, so I was really hoping to use it.
