----------------------------------
Summary: Add batch retrieve partition objects for metastore direct
sql
Key: HIVE-8295
URL: https://issues.apache.org/jira/browse/HIVE-8295
Project: Hive
Issue Type: Bug
Environment: Currently in MetastoreDirectSql partition objects are
constructed in a way that fetching partition ids first. However, if the
partition ids that match the filter is larger than 1000, direct sql will fail
with the following stack trace:

the memory footprint.
