Sandhya Sundaresan commented on TRAFODION-2874: ----------------------------------------------- Added syntax to return both filename and offset. The offset of a particular lobhandle within the LOB hdfs data file may help with UDF parallelization. We could colocate ESPs on the same node where the lobhandle offset is stored for efficient reading/streaming. > LOB: Add syntax to return filename of a LOB data file for external LOBs. > ------------------------------------------------------------------------- > > Key: TRAFODION-2874 > URL: https://issues.apache.org/jira/browse/TRAFODION-2874 > Project: Apache Trafodion > Issue Type: Bug > Components: sql-exe > Affects Versions: 2.3 > Reporter: Sandhya Sundaresan > Assignee: Sandhya Sundaresan > Priority: Major > > For external LOBs, Trafodion does not save the LOB data in it's internal > trafodion namespace. It saves only the LOB handle information and the actual > LOB data remains outside in users namespace in HDFS. So inserts are very > eifficient. During extract from an external LOB today, we extract the LOB > data from the external file and return it to the user. Need to extend the > Extract syntax to also be able to return the external LOB data filename alone > . -- This message was sent by Atlassian JIRA (v7.6.3#76005)
