cassandra cluster banlance

• 新集群，要事先规划好initial_token并在每台设好cassandra.yaml，计算工具有很多比如 this

# initial_token allows you to specify tokens manually.  While you can use # it with
# vnodes (num_tokens > 1, above) -- in which case you should provide a
# comma-separated list -- it's primarily used when adding nodes # to legacy clusters
# that do not have vnodes enabled.
initial_token: -9223372036854775808

 

• 已有集群添加节点

需要在新节点执行nodetool repair  之后在其他老节点执行nodetool cleanup
