    Description

      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.
