Adar Dembo resolved KUDU-2920. ------------------------------ Fix Version/s: 1.11.0 Resolution: Fixed Fixed in commit 324b8f2. Thanks, [~vladimir_committer]! > Block cache capacity validator shouldn't run on an NVM block cache > ------------------------------------------------------------------ > > Key: KUDU-2920 > URL: https://issues.apache.org/jira/browse/KUDU-2920 > Project: Kudu > Issue Type: Bug > Components: cfile > Affects Versions: 1.11.0 > Reporter: Adar Dembo > Assignee: Vladimir Verjovkin > Priority: Major > Labels: newbie > Fix For: 1.11.0 > > > As part of KUDU-2318, we added a validator to enforce that the block cache > capacity does not exceed the process' memory pressure threshold (defaults to > 60% of the overall memory limit). This makes sense for a DRAM-based block > cache, which competes for DRAM with Kudu (and thus its capacity should be a > fraction of the overall limit). > However, this doesn't make sense for NVM-based block caches, because the pool > of available NVM is distinct from the pool of available DRAM. In this case, > there really shouldn't be any relationship between the overall memory limit > and the block cache capacity. > We should relax the validator for NVM-based block caches. -- This message was sent by Atlassian Jira (v8.3.2#803003)
