Subject [jira] [Created] (SPARK-17861) Push data source partitions into metastore for catalog tables
Date Tue, 11 Oct 2016 00:58:20 GMT
Reynold Xin created SPARK-17861:
-----------------------------------

             Summary: Push data source partitions into metastore for catalog tables
                 Key: SPARK-17861
                 URL: https://issues.apache.org/jira/browse/SPARK-17861
             Project: Spark
          Issue Type: Improvement
          Components: SQL
            Reporter: Reynold Xin


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.
