Support input of linux files (on platform) into LOB columns. > 2. Support extract of LOB data into linux files on platform. > 3. Support input of hdfs files into LOB columns. > 4. Support extract of LOB data into hdfs files. > 5. Support chunking to input a very large external file into LOB columns. > 6. Use CQD concept to limit LOB max size and limit chunk size for extract > /input. > TBD > 7. Support for input/extract of external files off platform into LOB columns. > 8. Support in connectivity and driver for real LOB data type. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
