Subject [jira] Created: (PIG-86) load and store function should be file independent
Date Fri, 01 Feb 2008 18:45:07 GMT
load and store function should be file independent

                 Key: PIG-86
                 URL: https://issues.apache.org/jira/browse/PIG-86
             Project: Pig
          Issue Type: Improvement
            Reporter: Stefan Groschupf
            Priority: Critical

Currently pig is very file system centric for input LoadFunc and output StoreFunc.
However in many buzz usecases the data are not in the dfs directly but come from a remote
service. Also it is common to store the results into a database for a webbased ui.
There for I suggest to make filepath elements in the gramar optional.
For example:
A = load 'mydata' using PigStorage() // " 'myData' " would be optional  
STORE A into 'output.bz2' USING myStore(); //  " into 'output.bz2' " would be optional.

Current workaround for implementing Load and Store functions that work without file system
access is to create temporary dummy files since pig is checking for this files, even if the
load and store functions do not need those file.
