Re: JDBC input/output format

I highly doubt using Hadoop for that would be the most efficient  
solution, unless you have a "sharded" database infrastructure and  
extend the Hadoop database input/output format accordingly.

JDBC input/output format

Is anyone working on a JDBC RecordReader/InputFormat. I was thinking
this would be very useful for sending data into mappers. Writing data

possible.
