Reynold Xin updated SPARK-17861:
--------------------------------
Summary: Push data source partitions into metastore for catalog tables and
support partition pruning (was: Push data source partitions into metastore for
catalog tables)
> Push data source partitions into metastore for catalog tables and support
> partition pruning
> -------------------------------------------------------------------------------------------

> Key: SPARK-17861
> URL: https://issues.apache.org/jira/browse/SPARK-17861
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Reporter: Reynold Xin
> Priority: Critical
>
> Initially, Spark SQL does not store any partition information in the catalog
> for data source tables, because initially it was designed to work with
> arbitrary files. This, however, has a few issues for catalog tables:
> 1. Listing partitions for a large table (with millions of partitions) can be
> very slow during cold start.
> 2. Does not support heterogeneous partition naming schemes.
> 3. Cannot leverage pushing partition pruning into the metastore.
> This ticket tracks the work required to push the tracking of partitions into
> the metastore. This change should be feature flagged.
