> We use the default message store: LevelDB.
> On one broker with poor performance, we noticed a quite big store (file system wise) while there are zero messages in the queues.
> In concrete terms, the REST API reports for the aggregated dest-metrics:
>   'queue_items' => 0,
>   'queue_size' => 0,
> While on the box itself, in the data directory, we see:
> $ du -ks .
> 434992	.
> $ find . -type f | wc -l
> 471
> So 400MB and 471 files is a lot to hold zero messages...
> FWIW, the store page in the console reports something quite different:
> disk usage: 760.689 mb
> Log Status
> Log File             | Msg Refs   | File Size 
> 0000003a0eb4031b.log | 0          | 100.000 mb
> Index recovery starts from log position: 0000003a0eb4031b
> Append position: 0000003a13bed684
> Index Status
>                                Compactions
> Level  Files Size(MB) Time(sec) Read(MB) Write(MB)
> --------------------------------------------------
