Appending new data in Greenplum is very simple with Outsourcer.
Outsourcer takes the Refresh concept once step further by keeping tables up to date by identifying only the new data found in the source system to be inserted into Greenplum. This was designed with tables in mind that never have DELETE or UPDATE statements executed against it. A good example of this is a log table.
You don’t have to convert DDL, extract files, clean-up bad data, transfer the files, create YML files, etc to get your data into Greenplum! Outsourcer does it all!
