DETAILS

Nodes buffer write-sets to transmit to the cluster in the send queue. The node then sends the write-sets out and applies them together according to global ordering. Large numbers of entries in the send queue may indicate a network bottleneck.

This status variable provides the average number of write-sets since the node started or the last FLUSH STATUS statement.

EXAMPLES

Use the SHOW STATUS statement to view the current average of write-sets in the send queue:

SHOW STATUS LIKE "wsrep_local_send_queue_avg";

| Variable_name              | Value |
