in long run
kumar vishal created CARBONDATA-241:
---------------------------------------
Summary: OOM error during query execution in long run
Key: CARBONDATA-241
URL: https://issues.apache.org/jira/browse/CARBONDATA-241
Project: CarbonData
Issue Type: Bug
Reporter: kumar vishal
Assignee: kumar vishal
**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
