[jira] Resolved: (CASSANDRA-1750) support range queries w/RandomPartitioner

["Jonathan Ellis (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-1750?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Jonathan Ellis resolved CASSANDRA-1750.
---------------------------------------

    Resolution: Won't Fix

merging can only be done efficiently (i.e., "without reading every key into memory and doing a full sort") if the source ranges being merged are themselves ordered, which is not the case for RP.

>             Project: Cassandra
>          Issue Type: New Feature
>          Components: Core
>    Affects Versions: 0.7.0
>            Reporter: Robert Collins
>            Priority: Minor

> If we:
>  - store the original key in SSTables on disk
>  - send range queries to all nodes from the coordinator
>  - do a merge sort on the results
> range queries should be reasonably efficient: within a node, each sstable can efficiently answer the range query.
