> Carbon uses tablestatus file to record segment status and details of each
> segment during each load. This tablestatus enables carbon to support
> concurrent loads and reads without data inconsistency or corruption.
> So it is very important feature of carbondata and we should have clean
> interfaces to maintain it. Current tablestatus updation is shattered to
> multiple places and there is no clean interface, so I am proposing to
> refactor current SegmentStatusManager interface and bringing all tablestatus
> operations to single interface.
> This new interface allows to add table status to any other storage like DB.
> This is needed for S3 type object stores as these are eventually consistent.
