-----------------------------------
Assignee: Vladimir
> 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
> Priority: Major
> Labels: newbie
>
> 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.
