[Maria-discuss] eviction in information_schema?
How can i detect eviction of node from the cluster from "information_schema" other than decreasing of WSREP_CLUSTER_SIZE? Thanks,

This script will be executed on all nodes so you'll definitely detect it.

Does it mean "either/or", e.g. does it mean GLOBAL_STATUS table wouldn't be updated if i use --wsrep-notify-cmd option? For example, would WSREP_CLUSTER_SIZE be still updated after new node join if I use --wsrep-notify-cmd option? Thank you again,

Yes, wsrep_cluster_size gets updated in either case.
