DETAILS
Nodes buffer write-sets they receive from cluster in the received queue. The node then works through the received queue, applying them according to the global ordering to the local databases. Large numbers of entries in the received queue may trigger Flow Control to prevent the node from falling too far behind the cluster.
This status variable indicates the current number of write-sets in the received queue since the node started or since the last FLUSH STATUS statement.
EXAMPLES
Use the SHOW STATUS statement to view the current number of write-sets in the received queue:
SHOW STATUS LIKE "wsrep_local_recv_queue";
