Sandhya Sundaresan commented on TRAFODION-1473:
-----------------------------------------------
Still TBD :
1)On platform file input and extract are supported . Need to add support for
off platform files . Use of CURL interface is showing a few problems right now.
2) Connectivity and driver changes need to be done to support the actual LOB
datatype.
> Adding external buffer and file input and extract support for LOB datatypes
