Thanks tyler So the node I connect to Is the coordinate node. right?
But what’s the process about the replica? Firstly, the data will be inserted by the coordinate node. Secondly, it will find the first replica node based by the partitioner ,such randompartitioner, Thirdly, it will replicate the data based by the replica factor Any thing wrong?

It has nothing to do with which node(s) are replicas for the data. - Tyler 2011/1/11 raoyixuan (Shandy) <raoyix...@huawei.com<mailto:raoyix...@huawei.com>> I get confuse about the node which the data insert.I connect to one node by Cassandra-cli, and insert some data ,whether this node is the coordinate node? As I know, if I set the random partitioner, the coordinate node is whose the hash value bigger than the key’s hash value 华为技术有限公司 Huawei Technologies Co., Ltd.[Company_logo] Phone: 28358610 Mobile: 13425182943 Email: raoyix...@huawei.com<mailto:raoyix...@huawei.com> 地址：深圳市龙岗区坂田华为基地 邮编：518129 Huawei Technologies Co., Ltd.
