Q. How to go completely in-memory with Memtx? It seems that my data is not in memory. I use
collectgarbage(“count”) before and after I store 100K tuples, and the memory usage is less than the amount I’m storing. (2017)
A. Validate the space engine via console with
box.space.NAME.engine, where NAME is your space name.
collectgarbage(“count”) shows only the usage of Lua memory, not Tarantool DB memory.
