Subject [jira] [Created] (GORA-559) Improve gora-pig's GoraStorage with pushdown filters

--------------------------------------

             Summary: Improve gora-pig's GoraStorage with pushdown filters
                 Key: GORA-559
                 URL: https://issues.apache.org/jira/browse/GORA-559
             Project: Apache Gora
          Issue Type: Improvement
          Components: gora-pig
            Reporter: Alfonso Nishikawa


The aim is analyze and implement (if the conclusion is that it is possible) the pushdown filter
functionality for the Pig connector. When in a script there is a "FILTER" command, the condition
has to be passed to the datastore so the LOAD instruction does not load all the data. For
example, HBase would only accept key range filters at this moment, but this will be a great
improvement in performance.
