Different partitoners in Cassandra

Question

What are the different partitioners used in Apache Cassandra?
Can anyone explain?

Answer 1

• Murmur3Partitioner is the default partitioner. It is both improved and faster than RandomPartitioner. Uniformly distributes data based on MurmurHash function.64-bit hash value partition key with Range: 263 to 263-1

• RandomPartitioner was the default partitioner prior to Cassandra 1.2. It is used with virtual nodes. It has a Uniform Distribution.  It uses MD5 hash values with Range: 0 to 2127-1

• ByteOrderedPartioner is used for ordered partitioning. It orders rows lexically by key bytes. Using the ordered partitioner allows ordered scans by primary key. This means we can scan rows as though we were moving a cursor through a traditional index.

Hope this helps.
