> Metastore table cache enhancement
> ---------------------------------
>
> Key: HIVE-21787
> URL: https://issues.apache.org/jira/browse/HIVE-21787
> Project: Hive
> Issue Type: New Feature
> Components: Standalone Metastore
> Reporter: Sam An
> Assignee: Sam An
> Priority: Major
> Attachments: HIVE-21787.1.patch, HIVE-21787.2.patch
>
>
> Metastore currently uses black/white list to specify patterns of tables to
> load into the cache. Cache is loaded in one shot "prewarm", and updated by a
> background thread. This is not a very efficient design.
> In this feature, we try to enhance the cache for Tables with LRU to improve
> cache utilization.
