----------------------------------------------
Summary: Cache merged column stats from retrieved partitions
Key: HIVE-17265
URL: https://issues.apache.org/jira/browse/HIVE-17265
Project: Hive
Issue Type: Bug
Components: Statistics
Affects Versions: 3.0.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Currently when we retrieve stats from the metastore for a column in a
partitioned table, we will execute the logic to merge the column stats coming
from each partition multiple times.
Even though we avoid multiple calls to metastore if the cache for the stats in
enabled, merging the stats for a given column can take a large amount of time
if there is a large number of partitions.
