Summary: Track Read(), Open() and Write() operation time per disk
queue
Key: IMPALA-8884
URL: https://issues.apache.org/jira/browse/IMPALA-8884
Project: IMPALA
Issue Type: Improvement
Components: Backend
Reporter: Tim Armstrong
Assignee: Tim Armstrong
It would be useful for debugging I/O performance problems if we had histogram
stats for the time taken for various operations so that we could see if there
were slow operations on a particular disk (e.g. because of disk failure) or
from a particular remote filesystem.
