Renato Javier Marroquín Mogrovejo created GORA-175:
------------------------------------------------------

             Summary: Add data structure to handle in-memory records for the Gora-DynamoDB
module
                 Key: GORA-175
                 URL: https://issues.apache.org/jira/browse/GORA-175
             Project: Apache Gora
          Issue Type: New Feature
          Components: storage-dynamodb
    Affects Versions: 0.3
            Reporter: Renato Javier Marroquín Mogrovejo
             Fix For: 0.3


While writing the GoraCI module for the Gora-DynamoDB module an in-memory data structure was
not envisioned because there was not a clear advantage in terms of number of IO operations,
and "cost" in general. Some time ago, Amazon Web Services released the batchFuncionality which
we can use to persist and read groups of items in a single operation (25 for writes and 100
for reads). Now we can also decide on the consistency level used for these functionalities
