    move this to common getSplits, other wise validAndInvalidSegments can be 
null, if parallel deletion happens.

> **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
