Thierry Ygé commented on OAK-3606:
----------------------------------
[~tmueller] Let me know if I can provide this suggested patch also in a github
pull request with this reference. Or maybe you can use the patch and "refactor"
it if the namings of the classes/methods are not satisfying.
> Improvements for IndexStatsMBean usage
> --------------------------------------
>
> Key: OAK-3606
> URL: https://issues.apache.org/jira/browse/OAK-3606
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core
> Affects Versions: 1.3.9
> Reporter: Thierry Ygé
> Attachments: adding_new_MBean.patch,
> new_mbean_interface_and_implementation.patch
>
>
> When running integration tests, it is common to have the need to wait for the
> async indexes to have been executed. So that the test can successfully
> validate operations that depend on the search result.
> With the current IndexStatsMBean implementation it cannot return the start
> time of the last successful indexing. It provide a "LastIndexedTime" which is
> not sufficient to know if changes made recently are now indexed.
> The idea is to set the start time as value of a new attribute (i.e
> "StartLastSuccessIndexedTime") to the IndexStatsMBean.
> Then create a new Mbean that calculate from all existing IndexStatsMBean (as
> multiple are possible now) the oldest "StartLastSuccessIndexedTime".
> That will allow integration tests to be able to wait until that oldest
> "StartLastSuccessIndexedTime" is greater than the time it started to wait.
> Attached is a sample patch containing the necessary changes (for a Oak core
> 1.4.0-SNAPSHOT).
