Subject [jira] [Created] (ACCUMULO-4793) Prioritize/Reprioritize bulk import requests
Date Thu, 01 Feb 2018 19:10:00 GMT
Mark Owens created ACCUMULO-4793:

             Summary: Prioritize/Reprioritize bulk import requests
                 Key: ACCUMULO-4793
             Project: Accumulo
          Issue Type: Sub-task
          Components: master, tserver
            Reporter: Mark Owens

Accumulo currently provides mechanisms to initiate bulk imports and to list bulk imports in
progress. Scheduling of bulk import requests is not entirely deterministic, and most of the
execution of a bulk-import request is done in a non-preemptable manner. As such, any bulk
import which takes very long to complete can block bulk imports with higher operational priority
for significant periods.

To better support bulk-import-heavy applications, it would be nice if Accumulo would offer
additional mechanisms for controlling the scheduling and execution of bulk imports.

One such capability would be the ability to prioritize and re-prioritize bulk import requests.
Recent discussions with customers reveal this to be the highest priority on their feature
request wish list.
