The datasource api still have a problem that it do not support hybird fileformat table. Detail description about hybird fileformat table is in this issue: https://issues.apache.org/jira/browse/CARBONDATA-1377.
All partitions' fileformat of datasource table must be the same. So we can't change fileformat to carbodata by command "alter table table_xxx set fileformat carbondata;" So I think implement TableReader is the right way. -- Sent from: http://apache-carbondata-dev-mailing-list-archive.1130556.n5.nabble.com/
