ROUTE_CACHE_REPLICATION_GROUP view is used to query the routing cache information of the replication group (REPLICATION GROUP) cached by the current HyperNode, including details such as names and RPC addresses. This view displays only the local routing cache of the HyperNode to which the client is connected.Field Name | Type | Description |
bucket | varchar(21) | The bucket label of the bucketed routing cache. |
rep_group_id | bigint unsigned | The ID of the replication group. |
rep_group_meta_version | bigint unsigned | The metadata version number of the replication group. This version number is incremented when the topology of the replication group changes, such as during split (Split) or merge (Merge) operations of the replication group, or during the creation, deletion, splitting, or merging of data shards (Regions) within the group. Usage recommendations: This field is primarily used by the Tencent Cloud technical support team during in-depth troubleshooting. In daily Ops monitoring, you do not need to pay attention to the specific values of this field. |
rep_group_member_version | bigint unsigned | The member version number of the replication group. This version number is incremented when the members of the replication group change (such as adding, removing, promoting, or demoting members). Usage recommendations: This field is primarily used by the Tencent Cloud technical support team during in-depth troubleshooting. In daily Ops monitoring, you do not need to pay attention to the specific values of this field. |
rep_group_key_range_version | bigint unsigned | The key range version number of the replication group. This version number is incremented when the replication group undergoes split or merge operations, or when data shards within the group are created or deleted. Usage recommendations: This field is primarily used by the Tencent Cloud technical support team during in-depth troubleshooting. No special attention is required during daily Ops. |
rep_group_key_range_shrink_version | bigint unsigned | The key range compaction version number of the replication group. This version number is incremented when the replication group undergoes split operations or when data shards within the group are deleted. Usage recommendations: This field is primarily used by the Tencent Cloud technical support team during in-depth troubleshooting. No special attention is required during daily Ops. |
data_space_type | varchar(4) | The data space type of the replication group. Options include SYS: System data space.USR: User data space. |
node_id | bigint unsigned | The node ID where the replication group resides. |
node_name | varchar(128) | The node name where the replication group resides. |
node_rpc_addr | varchar(32) | The RPC address of the node where the replication group resides. |
