Stu Hood updated CASSANDRA-242:
-------------------------------
Attachment: CASSANDRA-242.diff
This patch implements 1) via a 'Collatable' abstract class, with
Collatable.String and Collatable.Bytes.
The main wart is that a Collatable.Bytes object will throw a RuntimeException
if you attempt to use it asString(), but it might still be a reasonable
approach for plugging in a Token that is never meant to be serialized or
decorated.
A third option would be to 3) Add an explicit third state for Tokens: plain,
decorated and -binary-. Once a token is in a binary state, it cannot be
converted back to plain or decorated. The explicitness is key.
> 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.
