> IndexStatsMBean should not reset start time
> -------------------------------------------
>
> Key: OAK-2223
> URL: https://issues.apache.org/jira/browse/OAK-2223
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core
> Reporter: Alex Parvulescu
> Assignee: Alex Parvulescu
> Priority: Minor
>
> Currently the IndexStatsMBean will reset the start time of an indexing cycle
> whenever it finishes. This introduces an interesting problem when you need to
> observe the indexing process. There's no real way of knowing if the cycle
> that finished after you started observing it started or not before that
> moment.
> Ex:
> ---------- (t1) --------- (t2) ----- (t1') ---- (t3) ---------->
> Let's assume an observer starts reading the indexing stats at (t2) and
> notices only the end time at (t3). Here we have a race condition: if the
> indexing cycle started at (t1) then the search should work but if the cycle
> actually started at (t1') the search won't work.
> Long story short, let's not reset the start time.
