Review comment:
   Thanks for working on it. Just a small suggestion. This showSegment 
testcase is meant for only segment display related test case. 
   
   can you move this test case to existing `InsertIntoCarbonTableTestCase` file 
?

[jira] [Created] (CARBONDATA-3994) Skip Order by for map task if it is sort column and use limit pushdown for array_contains filter

2020-09-16 Thread Ajantha Bhat (Jira)
Ajantha Bhat created CARBONDATA-3994:


 Summary: Skip Order by for map task if it is sort column and use 
limit pushdown for array_contains filter
 Key: CARBONDATA-3994
 URL: https://issues.apache.org/jira/browse/CARBONDATA-3994
 Project: CarbonData
  Issue Type: Bug
Reporter: Ajantha Bhat
Assignee: Ajantha Bhat


When the order by column is in sort column, every map task output will be 
already sorted. No need to sort the data again.
Hence skipping the order at map task by changing plan node from 
{{TakeOrderedAndProject}} --> {{CarbonTakeOrderedAndProjectExec}}
Also in this scenario collecting the limit at map task and Array_contains() 
will use this limit value for row scan filtering to break scan once limit value 
is reached.
Also added a carbon property to control this .
{{carbon.mapOrderPushDown._.column}}

Note: later we can improve this for other filters also to use the limit value.

### Why is this PR needed?

### What changes were proposed in this PR?
   This PR remove deleting INSERT_IN_PROGRESS and INSERT_OVERWRITE_IN_PROGRESS 
status segments during loading and compaction flow.
   
### Does this PR introduce any user interface change?
- No
   
### Is any new testcase added?
- No

   This PR remove deleting INSERT_IN_PROGRESS and INSERT_OVERWRITE_IN_PROGRESS 
status segments during loading and compaction flow.
   
### Does this PR introduce any user interface change?

   here method level comment says for new updates on the same segment we 
need to write new segment file with new segmentMetaDataInfo and merge with old 
segment file , i think that comment is pretty clear. It should be ok i think.
