sam-an-cloudera opened a new pull request #662: Hive-21787: Metastore table cache enhancement URL: https://github.com/apache/hive/pull/662 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.
