I'm running Apache Drill (1.18 master branch) in a docker with data stored in Parquet files on S3. When I run queries, even the most simple ones such as:
select name from `parquet/data/data.parquet` limit 1 The "Planning" time is 0.7-1.5 sec while the "Execution" is only 0.112 sec. These proportions are maintained even if I run the same query multiple times in a row. Since I'm trying to minimize query times to a minimum, I was wondering if such planning times (compared to execution) make sense and is there any way to reduce it? (some plan caching mechanism) Thanks, Avner
