[jira] [Commented] (MESOS-9224) De-duplicate read-only requests to master based on principal.

["Benno Evers (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MESOS-9224?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16655743#comment-16655743 ] 

Benno Evers commented on MESOS-9224:
------------------------------------

A review chain with the required changes can be found at https://reviews.apache.org/r/68131

The one thing that is still missing is a set of unit tests, which is appended to the chain as a wip-commit but proves to be unexpectly hard due to the fuzzy interface between http handler and master, and the caching being deeply buried in the master internals.

> "Identical" read-only requests can be batched and answered together. With batching available (MESOS-9158), we can now deduplicate requests based on principal.
