rpd_nodestable provides information about HeatWave nodes.
rpd_nodestable has these columns:
A unique identifier for the HeatWave node.
The number of cores used by the HeatWave node.
DRAMin MySQL 8.0.24)
The total memory in bytes allocated to the HeatWave node.
The status of the HeatWave node. Possible statuses include:
The node is not operational.
IP的一个ddress of the HeatWave node.
The port on which the HeatWave node was started.
Node memory usage in bytes. The value is refreshed every four seconds. If a query starts and finishes in the four seconds between refreshes, the memory used by the query is not accounted for in the reported value. Introduced in MySQL 8.0.24.
rpd_nodestable is read-only. DDL, including
TRUNCATE TABLE, is not permitted.
rpd_nodestable may not show the current status for a new node or newly configured node immediately. The
rpd_nodestable is updated after the node has successfully joined the cluster.
If additional nodes fail while node recovery is in progress, the newly failed nodes are not detected and their status is not updated in the
performance_schema.rpd_nodestable until after the current recovery operation finishes and the nodes that failed previously have rejoined the cluster.
