> Improve the logic used to find recorded regions during invalid list pruning
> ---------------------------------------------------------------------------
>
> Key: TEPHRA-230
> URL: https://issues.apache.org/jira/browse/TEPHRA-230
> Project: Tephra
> Issue Type: Bug
> Affects Versions: 0.10.0-incubating
> Reporter: Poorna Chandra
> Assignee: Poorna Chandra
> Fix For: 0.12.0-incubating
>
>
> During an invalid list pruning run, the plugin records the regions present on
> the HBase cluster at that time. It also records the count of regions as a
> checksum.
> While reading the list of recorded regions, if the checksum does not match
> the number of regions read at time {{t}}, then the plugin will move on to
> regions at time {{t - 1}}. However, the {{t-1}} computation in inefficient
> today, and leads to microsecond decrements. It can be improved to use the
> time at which the current set of regions were recorded.
