系统-集群

包含有关配置文件中可用的集群及其中的服务器的信息。

列:

cluster (String) — The cluster name.
shard_num (UInt32) — The shard number in the cluster, starting from 1.
shard_weight (UInt32) — The relative weight of the shard when writing data.
replica_num (UInt32) — The replica number in the shard, starting from 1.
host_name (String) — The host name, as specified in the config.
host_address (String) — The host IP address obtained from DNS.
port (UInt16) — The port to use for connecting to the server.
user (String) — The name of the user for connecting to the server.
errors_count (UInt32)-此主机无法到达副本的次数。
estimated_recovery_time (UInt32)-剩下的秒数，直到副本错误计数归零，它被认为是恢复正常。

请注意 errors_count 每个查询集群更新一次，但 estimated_recovery_time 按需重新计算。所以有可能是非零的情况 errors_count 和零 estimated_recovery_time，下一个查询将为零 errors_count 并尝试使用副本，就好像它没有错误。
