> **Problem:** During long run query execution is taking more time and it is
> throwing out of memory issue.
> **Reason**: In compaction we are compacting segments and each segment
> metadata is loaded in memory. So after compaction compacted segments are
> invalid but its meta data is not removed from memory because of this
> duplicate metadata is pile up and it is taking more memory and after few days
> query exeution is throwing OOM
> **Solution**: Need to remove invalid blocks from memory
