Detailed Description

Class used to increase an atomic value when UDF functions are being initialized.

If initialization fails the value will be decreased.

number_udfs_running works together with plugin_is_stopping so when group replication is stopping, all new udf will fail to start and server will wait for the running ones to finish.
