--------------------------------------
Summary: Don't sync tuple cache file contents to disk immediately
Key: IMPALA-13478
URL: https://issues.apache.org/jira/browse/IMPALA-13478
Project: IMPALA
Issue Type: Task
Components: Backend
Affects Versions: Impala 4.5.0
Reporter: Joe McDonnell
Currently, the tuple cache file writer syncs the file contents to disk before
closing the file. This slows down the write path considerably, especially if
disks are slow. This should be moved off of the fast path and done
asynchronously. As a first step, this can remove the sync call and close the
file without syncing. Other readers are still able to access it, and the kernel
will flush the buffers as needed.
