Your keys cannot be an encoded as binary for OPP, since Cassandra will attempt to decode them as UTF-8, meaning that they may not come back in the same format.
0.7 supports byte keys using the ByteOrderedPartitioner, and tokens are specified using hex. -----Original Message----- From: "Mark Jones" <mjo...@imagehawk.com> Sent: Friday, April 23, 2010 10:55am To: "user@cassandra.apache.org" <user@cassandra.apache.org> Subject: RE: org.apache.cassandra.dht.OrderPreservingPartitioner Initial Token So if my keys are binary, is there any way to escape the keysequence in? I have 20 bytes (any value 0x0-0xff is possible) as the key. Are they compared as an array of bytes? So that I can use truncation? 4 nodes, broken up by 0x00, 0x40, 0x80, 0xC0? -----Original Message----- From: Jonathan Ellis [mailto:jbel...@gmail.com] Sent: Friday, April 23, 2010 10:22 AM To: user@cassandra.apache.org Subject: Re: org.apache.cassandra.dht.OrderPreservingPartitioner Initial Token a normal String from the same universe as your keys.
