> For the *carbon.invisible.segments.preserve.count* configuration, it is not
> working as expected.
> +*Steps to reproduce:*+
> 1) Setting up "*carbon.invisible.segments.preserve.count=20"* in
> carbon.properties and restarting the thrift server.
>
> 2) After performing Loading 40 times and Compaction 4 times.
> 3) Perform clean files, so that the tablestatus.history file would be
> generated with invisible segments details.
> So Total 44 segments would be created including visible and invisible
> segments.(40 load segment (like segment ID from 0,1,2...39) + 4 compacted new
> segment(like 0.1,20.1,22.1,0.2))
> In that, *41 segments information are present in the "tablestatus.history"
> file(*which holds invisible(marked for delete and compacted) segments
> details) and 3 segments information are present in the "tablestatus"
> file(which holds visible segments(0 .2 -final compacted segment) along with
> (1^st^ segment - 0th segment) and (last segment-39th segment)). *But
> invisible segment preserve count is configured to 20, which is not followed
> for the tablestatus.history file.*
> +*Expected result:*+
> tablestatus.history file should preserve only the latest 20 segments, as per
> the configuration.
> +*Actual result:*+
> tablestatus.history file is having 41 invisible segments details.(which is
> above the configured value: 20)
>
> This is tested with ANT cluster.
