Jonathan Ellis commented on CASSANDRA-242:
------------------------------------------
Thanks for splitting the patch. Looks like a good approach.
Patch 1: let's use an annotation instead of special interface to indicate
order-preserving-ness
Both, but especially patch 2: please follow

> Implement method to "evenly" split a Range

> Two tickets currently depend on being able to deterministically split a Range
> object into two "even" Ranges.
> This can be accomplished with RandomPartitioner/BigIntegerToken by taking the
> average of the tokens, but the OrderPreservingPartitioner/StringToken
> implementation uses a Java Collator to define the sort order of Tokens, which
> means that they are not necessarily sorted in byte/char order.
> Collator.getCollationKey(String).toByteArray() gets you a sortable byte
> array, but there is no publicly accessible API for converting a similar byte
> array back into a String.
