Hello,
I am planning to use LMDB to create a resonably large database, few
TBs, >
500mil keys, on a Fusion IO flash storage. Memory to storage ratio
of the
available hardware is about 1:10
Assuming the caching of "5 to 10%" of most-frequently-accessed data
is good
enough for my use-case, is this a valid/legitimate use of LMDB ? Or
am I using
the wrong tool for the job?
Benchmarks of various DB engines on Fusion IO storage, with DBs 5x
larger than RAM, available on http://symas.com/mdb/ondisk/
The answer also depends on the size of your data records.
