Bitcask keeps all the *keys* in RAM. That's like an index in database terms. So even if you have 9Gb of data, you should only have a tiny fraction of that in keys, in memory.
So you might have some other problem going on there? Riak uses quite a bit of memory for LevelDB buffers, by default, so maybe you're seeing something like that? -Toby On Thu, 2 Jul 2015 at 21:55 Anita Wong <anita.w...@talkboxapp.com> wrote: > HI, > > I’ve got a problem in using Riak-CS as file storage cluster. > > Now the bitcask folder has 9GB of data in it, and the RAM usage of Riak is > >8GB. > > Just checked that the bitcask backend will put all the keys into the RAM, > but how come now I would get this large amount of RAM being used? > >
