dynamodb-batchwriter

New creates a new BatchWriter that will write to table `tableName` using `client`.

NewWithPrimaryKeys creates a new BatchWriter using `primaryKeys` as the specified primary keys instead of getting them from a call to DescribeTable.

WrapDeleteItem wraps a DeleteRequest to use with BatchWriter.Add.

WrapPutItem wraps a PutRequest to use with BatchWriter.Add.

BatchWriter wraps a dynamodb client to expose a simple API that buffers requests and takes advantage of BatchWriteItem behind the scenes.
