-----------------------------------
Summary: optimizer a simple query
Key: SPARK-23027
URL: https://issues.apache.org/jira/browse/SPARK-23027
Project: Spark
Issue Type: Bug
Components: Optimizer
Affects Versions: 2.0.1
Reporter: wangminfeng
When i use spark sql to do ad-hoc query, i have data partitioned by event_day,
event_minute, event_hour, data is large enough，one day data is about 3T， we
saved 3 month data.
But when query use a non-existent day， get optimizedPlan is too slow.
i use “sparkSession.sessionState.executePlan(logicalPlan).optimizedPlan” get
optimized plan， for five minutes，i can not get it. Query is simple enough, like:
SELECT
event_day
FROM db.table t1
WHERE (t1.event_day='20170104' and t1.event_hour='23' and t1.event_minute='55')
LIMIT 1
