Description

We find it useful to tune merge policy not blindly but looking on segment size and fill ratio.

We're working on a patch that adds a tab to admin page with McCandless-style of segment visualization.

Draft UI is attached (currenly as part of admin.extra).

Please share your ideas if it's ok to put the code in core admin.
