Subject [jira] Commented: (PIG-652) Need to give user control of OutputFormat
Date Tue, 10 Feb 2009 18:56:59 GMT

Alan Gates commented on PIG-652:
--------------------------------

Sorry, the missing piece is that pig serializes the StoreFunc on the front end and deserializes
it on the back end, so it can store things in member variables and then have them on the backend.
 But, for a more elegant proposal see, PIG-602.  We could add this as part of these changes
so that your store function could use that as a transport mechanism.

> Pig currently allows users some control over InputFormat via the Slicer and Slice interfaces.
 It does not allow any control over OutputFormat and RecordWriter interfaces.  It just allows
the user to implement a storage function that controls how the data is serialized.  For hadoop
tables, we will need to allow custom OutputFormats that prepare output information and objects
needed by a Table store function.
