Hello! 1) Roughly yes: you need to do checkpoint, RAM does not need wal/ but only db/, and also you need checkpoint page buffer with persistence which you can add to memory region when going pure-RAM.
2) I don't think that per cache metrics exist. Regards, -- Ilya Kasnacheev пн, 25 февр. 2019 г. в 15:02, newigniter <[email protected]>: > Yes of course. > All of my data is imported through sql.
