What is the use of ram memory that keeps memsql to be active

Hi guys,
I had a disk memory problem, I was able to free more than 20 GB by deleting an entire database …
But I still find 10 gb of ram consumed by memsql, when in dashboard it shows only 2 gb
Could you explain the reason?

It could be that the MemSQL process allocated that much memory from the OS and it won’t just give it back. If a little downtime is not an issue, consider restarting memsql and see if that changes things.

Paste the output of “SHOW STATUS EXTENDED” from the memsql running on that host.

MemSQL will cache memory when memory use is low (Buffer_manager_cached_memory).
