Attachment: (was: start.png)
> Accelerate Spark Plan generation when Spark SQL read large amount of data
> -------------------------------------------------------------------------
>
> Key: SPARK-25038
> URL: https://issues.apache.org/jira/browse/SPARK-25038
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 2.3.1
> Reporter: Jason Guo
> Priority: Critical
>
> When Spark SQL read large amount of data, it take a long time (more than 10
> minutes) to generate physical Plan and then ActiveJob
>
> Example:
> There is a table which is partitioned by date and hour. There are more than
> 13 TB data each hour and 185 TB per day. When we just issue a very simple
> SQL, it take a long time to generate ActiveJob
>
> The SQL statement is
> {code:java}
> select count(device_id) from test_tbl where date=20180731 and hour='21';
> {code}
>
> The SQL is issued at 2018-08-07 08:43:48
> !image-2018-08-07-08-52-00-558.png!
> However, the job is submitted at 2018-08-07 08:46:05, which is 2minutes and
> 17 seconds later than the SQL issue time
