> Project: Apache Trafodion
> Issue Type: Task

> LOB datatype is disabled in Trafodion until the following support is fully
> in.
> Here are the list of tasks and items to support :
> 1. 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.
