redis集群设计

Question

有两台服务器A,B做redis集群。 数据的写入是平均分配到二台服务器上，还是先写完一台服务器在向另一台服务器写数据呢。

二种情况各有什么优势，

Answer 1

You can try the redis cluster that comes with Redis 3.0 or above. Redis cluster uses data sharding instead of consistency hashing to implement: a Redis cluster contains 16384 hash slots, database Each key in belongs to one of the 16384 hash slots. The cluster uses the formula CRC16(key) % 16384 to calculate which slot the key belongs to. The CRC16(key) statement is used to calculate the CRC16 checksum of the key key. . Hope the above answer is helpful to you
