> Project: Apache Storm
> Issue Type: Improvement
> Components: storm-cassandra

> Reporter: Yohei Kishimoto
> Priority: Minor

> Current implementation in `TridentResultSetValuesMapper::map` restricts a
> SELECT query to return one row. In `StateQueryProcessor::finishBatch`, it
> checks the equality between the result size of `batchRetrieve` and input
> tuple size. When the number of result rows is less than 1 or greater than 1,
> it breaks the condition and an exception is thrown.
> We should accept arbitrary number of rows by adjusting List dimensions.
