Akash R Nilugal (Jira)
Jin Zhou created CARBONDATA-1030:
------------------------------------

             Summary: Support reading specified segment or carbondata file
                 Key: CARBONDATA-1030
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-1030
             Project: CarbonData
          Issue Type: Improvement
            Reporter: Jin Zhou
            Priority: Minor


We can query whole table in SQL way currently, but reading specified segments or data files is useful in some scenarios such as incremental data processing.

Hi

+1 for this feature.
How about the DDL script as below :
carbon.sql("select * from carbontable in segmentid(0,3,5,7) where filter
conditions").show()

Regards
Liang
