- # DB Test 44 {access method}
- # System integration DB test: verify that locking, recovery, checkpoint,
- # and all the other utilities basically work.
- #
- # The test consists of $nprocs processes operating on $nfiles files. A
- # transaction consists of adding the same key/data pair to some random
- # number of these files. We generate a bimodal distribution in key
- # size with 70% of the keys being small (1-10 characters) and the
- # remaining 30% of the keys being large (uniform distribution about
- # mean $key_avg). If we generate a key, we first check to make sure
- # that the key is not already in the dataset. If it is, we do a lookup.
- #
- # XXX This test uses grow-only files currently!
