[jira] [Created] (TRAFODION-2948) LOB: Support for inlined LOBs

Sandhya Sundaresan created TRAFODION-2948:
---------------------------------------------

             Summary: LOB: Support for inlined LOBs 
                 Key: TRAFODION-2948
                 URL: https://issues.apache.org/jira/browse/TRAFODION-2948
             Project: Apache Trafodion
          Issue Type: New Feature
    Affects Versions: any
            Reporter: Sandhya Sundaresan
            Assignee: Sandhya Sundaresan


Today any LOB column in a Trafodion table is stored in an external HDFS file. For LOBs that are lessthan 16MB, we shoudl automatically allow them to be inlined. We need to introduce a new flag type in the LOB handle that tells us if it's an inlined LOB or an external LOB. We could allow syntax during insert/update to specify that a LOB needs to be inlined. Or we could designate a column of the table to always be an inlined LOB so it'll be set at creation time. Insert/Updating a larger than 16MB lob into that column would be an error.
