> Project: IMPALA
> Issue Type: Improvement
> Components: Infrastructure
> Reporter: Joe McDonnell

> Priority: Major
> Fix For: Impala 4.4.0
>
>
> DiskIoMgr is using a large number of threads, most of which are idle. This
> makes minidumps/cores larger and slower to process. For developers, this can
> slow down gdb attach and navigating through the threads.
> For our test infrastructure / development, we can reduce the threads for
> filesystems that are not the TARGET_FILESYSTEM. If we aren't testing ABFS,
> then we don't need the full set of ABFS threads. In general, we can reduce
> almost all of the non-TARGET_FILESYSTEM DiskIoMgr thread counts to 1.
> We should have a way to turn it off, but it seems like this could be the
> default mode.
