---------------------------------------
Summary: Improve analyze statement execution time for partitioned
tables
Key: HIVE-19095
URL: https://issues.apache.org/jira/browse/HIVE-19095
Project: Hive
Issue Type: Improvement
Reporter: Zoltan Haindrich
tpcds@1TB:
{{analyze web_returns compile statistics for columns}}
both compile and stat task execution is slow;
there were ~2000 calls to get_partitions_ps_with_auth which took 2minutes
stattask seems to be slow because it seems like the metastore updates the stats
1 by 1 for each partition
{flushCache=1, optimizer=565, open_txns=8, TezCompiler=5248, get_table_req=69,
get_partitions_ps_with_auth=130333}
