-----------------------------------------
@jbellis:
I can't find the specific point in the wiki that confused me. It might be that
the various partitioners support byte-level ordering of keys while the Thrift
API only supports UTF-8 encoding on the wire? I think that if you were to add
a simple explanation on the API page (http://wiki.apache.org/cassandra/API)
that keys are always Strings and encoded as UTF-8 on the wire and on disk, then
that would work for me.
btw, as you guys edge toward graduation, you'll have to be careful about having
only committers edit artifacts; otherwise, changes have to go through the
submission and patch process to be clean.
@forsini:
I have to go back and reread the documentation. When I first read through the
Cassandra documentation, I didn't pick up that row keys are always Strings.

> Key: CASSANDRA-626
> URL: https://issues.apache.org/jira/browse/CASSANDRA-626
> Project: Cassandra
> Issue Type: Improvement
> Components: Documentation & website
> Affects Versions: 0.5
> Reporter: Paul R. Brown
> Priority: Minor
>
> As part of some experiments with Cassandra, I wanted to build a column space
> with row keys that are Long (64-bit binary blocks) and column names that are
> Long, and this seems to be supported by the data configuration infrastructure:
> {code}<ColumnFamily ColumnType="Super"
> CompareWith="LongType"
> CompareSubcolumnsWith="LongType"
> Name="UserEvent"/>{code}
> But there is no obvious way to perform the insert over the Thrift interface
> via Java; I tried various ways of turning the Long bits into Strings for the
> API call, but the insert call returns:
> {code}Exception in thread "main" InvalidRequestException(why:A long is
> exactly 8 bytes){code}
> The status of keys as either byte[] or String and the mechanisms for
> inserting need to be clarified and surfaced in the API.
