--------------------------------------
Assignee: Joe McDonnell
> Add support for building against other malloc implementations (e.g. jemalloc)
> -----------------------------------------------------------------------------
>
> Key: IMPALA-14702
> URL: https://issues.apache.org/jira/browse/IMPALA-14702
> Project: IMPALA
> Issue Type: Task
> Components: Backend
> Affects Versions: Impala 5.0.0
> Reporter: Joe McDonnell
> Assignee: Joe McDonnell
> Priority: Major
>
> Impala builds against gperftools tcmalloc. Other malloc implementations like
> jemalloc and Google's tcmalloc have different designs that would be
> interesting to test. We know that there are performance improvements related
> to avoiding gperftool tcmalloc's aggressive decommit setting. It would be
> nice to test that against other malloc implementations (or forgo overriding
> malloc altogether).
