-----------------------------------
Resolution: Fixed
Fixed in DRILL-7523
> OOM planning a certain query
> ----------------------------
>
> Key: DRILL-8063
> URL: https://issues.apache.org/jira/browse/DRILL-8063
> Project: Apache Drill
> Issue Type: Bug
> Components: Query Planning & Optimization
> Affects Versions: 1.19.0
> Reporter: James Turton
> Assignee: Vova Vysotskyi
> Priority: Critical
>
> This looks like an infinite planning bug in Calcite. To reproduce, copy the
> two referenced TPCH Parquet files from contrib/data/tpch-sample-data/parquet/
> to dfs.tmp then run the following. Uncommenting the `magic_fix` column is
> just one of the changes that can be made to make the query planning succeed.
>
> {code:java}
> select
> p_brand,
> -- 'foobar' as magic_fix,
> case
> when f1 then v1
> else null
> end as `m_1`,
> case
> when f1 then v2
> else null
> end as `m_2`
> from
> (select
> part.`p_brand`,
> sum(t.l_extendedprice) as v1,
> avg(t.l_extendedprice) as v2,
> true as f1
> from
> dfs.tmp.`lineitem.parquet` `t`
> inner join dfs.tmp.`part.parquet` part on `t`.`l_partkey` =
> part.`p_partkey`
> group by part.`p_brand`) as `t2`; {code}
