----------------------------------
Summary: optimize slave ID comparison in filter lists
Key: MESOS-3052
URL: https://issues.apache.org/jira/browse/MESOS-3052
Project: Mesos
Issue Type: Bug
Components: allocation
Reporter: James Peach
With a large number of frameworks that all refuse offers permanently, the
filter lists can get long. Comparing the slave IDs on the long filter lists
ends up taking noticeable time.
Since each filter list traversal matches on on a single slave ID, we can
optimize this by hashing the slave ID and checking the hash before comparing
the full slave ID. This is a 5% - 10% performance win.
