Avi Kivity	f915ff1fcd	dht: introduce i_partitioner::shard_of() and implement msb sharding ... Make sharding partitioner-specific, since different partitioners interpret the byte content differently. Implement it by extracting the shard from the most significant bits, which can be used to minimize cross shard traffic for range queries, and reduces sstable sharing.	2015-08-03 20:17:40 +03:00

Paweł Dziepak	ede9886f50	dht: add byte_ordered_partitioner ... Some of the tests in DTEST take advantage of the fact that ByteOrderedPartitioner guarantees certain ordering of partition keys. Signed-off-by: Paweł Dziepak <pdziepak@cloudius-systems.com>	2015-07-09 23:43:16 +02:00
