hi Gabryel, as memstore is a very simple object store backend. i am
afraid we don't have a thorough document on it at this moment.
probably the best reference is its source code.
i think the use cases of memstore is for profiling and prototyping, as
its name suggests, memstore is an in-memory store. so one can expect
that all I/O targeting it will finish in a jiffy. this property helps
us to identify the bottleneck in the other parts of OSD, for instance,
the messenger, OSD and PG. currently, we are developing a next
generation OSD dubbed "crimson", which is also using a variant of
memstore for testing.
