Good morning all,
Sorry to spam the sqlite list but I thought this might be the best place to
ask.
I'm trying to find an (embedded) database package to fill a specific need
and wondered if anyone can provide a recommendation?
Requirements:
* disk based storage
* As freaking FAST as possible! (this implies a single file for the
database, non sparse files are best)
* small footprint
* can store binary data up to multi megabyte
* must be able to quickly locate groups of keys (or provide in order
traversal and seek to a substring of a key)
* thread safe is optional, but nice
* does not need any kind of query language
* low numbers of records (100's - 10,000's)
* small keys (<100 bytes)
* no locking or concurrency
* linux and windows compatibility a big plus
I'm considering some of the dbm variants but so far only qdbm comes close.
I'm doing timing tests on qdbm
now but I believe that design has an undesirable feature for my use. It's
very fast generally but occasionally
takes several seconds (ouch!) to perform a next key retrieval. I believe
the
btree node retrieval is at fault.
Thanks for your help,
Jay
