----------------------------------------
Summary: support presto-carbon to read sdk cabron files
Key: CARBONDATA-3158
URL: https://issues.apache.org/jira/browse/CARBONDATA-3158
Project: CarbonData
Issue Type: Improvement
Reporter: Ajantha Bhat
Assignee: Ajantha Bhat
Currently, carbon SDK files output (files without metadata folder and its
contents) are read by spark using an external table with carbon session.
But presto carbon integration doesn't support that. It can currently read
only the transactional table output files.
Hence we can enhance presto to read SDK output files. This will increase
the use cases for presto-carbon integration.
The above scenario can be achieved by inferring schema if metadata folder
not exists and
setting read committed scope to LatestFilesReadCommittedScope, if
non-transctional table output files are present.
