gabriele renzi updated CASSANDRA-594:
-------------------------------------
Attachment: (was: CASSANDRA-543.patch)
> Add "count" and "del" commands to CLI
> -------------------------------------
>
> Key: CASSANDRA-594
> URL: https://issues.apache.org/jira/browse/CASSANDRA-594
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Affects Versions: 0.5
> Environment: all
> Reporter: gabriele renzi
> Fix For: 0.5
>
> Original Estimate: 0.17h
> Remaining Estimate: 0.17h
>
> currently cassandra-cli does not
> * allow removal of columns
> * allow visualization of column count for a row (useful for large sets)
> The attached patch fixes this issue by adding three more commands, del <key>,
> del <key><col>, count <key>.
> No new tests were addded as I could not find any for the CLI, if I have time
> I'll maybe add some but this is not likely to happen soon.
> As an aside, IMVHO the cassandra cli would be better as a small lib loaded
> within jirb/jython, parsing would come for free, flexibility would be much
> larger and it could be autogenerated from the thrift api.
