Hi, all, I want to use a column family to save some runtime data, which is small so I set that CF in memory to increase the performance, and the user data is still save in a normal CF. My question is: will the data in the in-memory column family get lost, if there is a failure of regionServer? Or in other words, is the data in an in-memory CF as safe as in an ordinary CF? No difference?
I could do test myself, but it needs some time, so I would like to be lazy and ask for help here :) If someone happened to know the answer, thanks in advance! Thanks, Ming
