[jira] [Commented] (ARROW-10226) [Rust] [DataFusion] TPC-H query 1
no longer completes for 100GB dataset
[ https://issues.apache.org/jira/browse/ARROW-10226?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17209937#comment-17209937 ]
Andy Grove commented on ARROW-10226:
------------------------------------
The query also returns the wrong results ... grouping by l_comment (high cardinality) instead of l_returnflag (low cardinality)

> Key: ARROW-10226
> URL: https://issues.apache.org/jira/browse/ARROW-10226
> Project: Apache Arrow
> Issue Type: Bug
> Components: Rust, Rust - DataFusion
> Reporter: Andy Grove
> Assignee: Andy Grove
> Priority: Blocker
> Fix For: 2.0.0
>
>
> I re-installed my desktop a few days ago (now using Ubuntu 20.04 LTS) and when I try and run the TPC-H benchmark, it never completes and eventually uses up all 64 GB RAM.
> I can run Spark against the data set and the query completes in 24 seconds, which IIRC is how long it took before.
> It is possible that something is odd on my environment, but it is also possible/likely that this is a real bug.
> I am investigating this and will update the Jira once I know more.
> I also went back to old commits that were working for me before and they show the same issue so I don't think this is related to a recent code change.
