> Need a additional method for Hadoop Range Queries.
> --------------------------------------------------
>
> Key: CASSANDRA-747
> URL: https://issues.apache.org/jira/browse/CASSANDRA-747
> Project: Cassandra
> Issue Type: New Feature
> Components: Core
> Affects Versions: 0.6
> Environment: Need to add additional method for Range queries from
> Hadoop.
> Reporter: Vijay
> Assignee: Vijay
> Priority: Minor
>
> Hadoop Integration might need the following.....
> 1) API to return the List of splits, given the number of splits.
> Using this tokens we cam span equal number of MR Jobs (Have a configuration
> in MR Job - This will be according to the complexity in processing), which
> will say how many map tasks per partition and span those process.
> 2) Start token to stream.... API
> Input will be Range(String startKey, Token start, Token finish, int
> limit).... return will be
> If Startwithkey is empty we will use the token1 as the starting point for
> the stream, else we will use startwithkey to specify the key to start with?
> Make sense?
> So each MR jobs will get the range of data from the Cassandra and will do
> processing on it, it can also stream the data and doesn't need to get all of
> it.
