> CachedStore: prewarm improvement (avoid multiple sql calls to read partition
> column stats), refactoring and caching some aggregate stats
> ----------------------------------------------------------------------------------------------------------------------------------------
>
> Key: HIVE-17495
> URL: https://issues.apache.org/jira/browse/HIVE-17495
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Reporter: Vaibhav Gumashta
> Assignee: Vaibhav Gumashta
> Attachments: HIVE-17495.1.patch, HIVE-17495.2.patch,
> HIVE-17495.3.patch, HIVE-17495.4.patch, HIVE-17495.5.patch,
> HIVE-17495.6.patch, HIVE-17495.7.patch
>
>
> Only when CachedStore is enabled, we would like to make the following
> optimizations:
> 1. During CachedStore prewarm, use one sql call to retrieve column stats
> objects for a db and store it in the cache.
> 2. Cache some aggregate stats (e.g. aggregate stats for all partitions,
> which seems to be commonly used) for query compilation speedup.
> 3. There was a bug in {{MetaStoreUtils.aggrPartitionStats}}, which would use
> an iterator.next w/o checking with iterator.hasNext. This patch refactors
> some code to fix that.
