Joe McDonnell updated IMPALA-10803:
-----------------------------------
Target Version: Impala 4.3.0 (was: Impala 4.1.0)
> Switch default data cache eviction policy to LIRS
> -------------------------------------------------
>
> Key: IMPALA-10803
> URL: https://issues.apache.org/jira/browse/IMPALA-10803
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Affects Versions: Impala 4.1.0
> Reporter: Joe McDonnell
> Assignee: Joe McDonnell
> Priority: Major
>
> The data cache currently defaults to using LRU for the cache eviction policy.
> In IMPALA-8690, we added support for LIRS, a scan resistant eviction policy.
> This is now stable, and we should switch to using LIRS by default. It is
> likely to have better performance characteristics than LRU for most workloads.
