SHOW RESOURCE GROUPS / GROUP

Note

SDK methods: listResourceGroups, describeResourceGroup.

Resource-group queries

SHOW RESOURCE GROUPS;
SHOW RESOURCE GROUP __default_resource_group;

These commands read native cluster-level resource-group information. They do not filter by the current JDBC database, change resource configuration, or move nodes. The list returns one VARCHAR RESOURCE_GROUP per row with no ordering guarantee. JDBC maxRows can limit returned rows.

A description returns one row: RESOURCE_GROUP is the name; CAPACITY and AVAILABLE_NODES are INTEGER; LOADED_REPLICAS, OUTGOING_NODES, and INCOMING_NODES are VARCHAR JSON objects preserving the SDK's collection replica-count, outgoing-node-count, and incoming-node-count maps. CONFIG is a VARCHAR JSON configuration object, or SQL NULL when absent from the SDK response. NODES is a VARCHAR JSON node array. Field meanings and state come from the server; queries neither wait for transfers nor infer additional scheduling state from counts. List and description calls are independent snapshots.
