URL: https://issues.apache.org/jira/browse/HIVE-23901
Project: Hive
Issue Type: Improvement
Components: Standalone Metastore, Statistics

Assignee: Yu-Wen Lai
When aggregating the column stats for a big partitioned table, we observed a
large proportion of time spent in getLogger(). If we declare it as static, the
execution time of aggregate can be greatly improved.
