From 5fb9c58b03f18f34d95dc7045e8065feb58e2352 Mon Sep 17 00:00:00 2001 From: Sage Weil Date: Thu, 22 Feb 2018 13:18:22 -0600 Subject: [PATCH] os/bluestore: split memory 50/50 between bluestore and rocksdb We don't yet have a clear answer on where our memory is best spent once we are above kv_min. Previous testing showed that bluestore was a better bet, but that predates the enabling of bloom filters and/or inclusion of bloom filters in the rocksdb cache size. A 50/50 split hedges out bets until we have more information. At worst we are misusing half of any addition memory given to the OSD (vs potentially more than that for any config that steers more memory one way or the other). We still spend no memory on data currently. That should probably change.
