As the only documentation, I can find is https://ceph.io/geen-categorie/ceph-real-men-use-the-memstore-backend/ 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. -- Regards Kefu Chai _______________________________________________ Dev mailing list -- dev@xxxxxxx To unsubscribe send an email to dev-leave@xxxxxxx
