This variable is always  0 , and is deprecated; expect it to be removed in a future version. This variable is available only if the source-side semisynchronous replication plugin is installed. The total number of times the source waited for replica replies. This variable is available only if the source-side semisynchronous replication plugin is installed. The number of times the source turned off semisynchronous replication. This variable is available only if the source-side semisynchronous replication plugin is installed. The number of commits that were not acknowledged successfully by a replica. This variable is available only if the source-side semisynchronous replication plugin is installed. Whether semisynchronous replication currently is operational on the source. The value is  ON  if the plugin has been enabled and a commit acknowledgment has occurred. It is  OFF  if the plugin is not enabled or the source has fallen back to asynchronous replication due to commit acknowledgment timeout. This variable is available only if the source-side semisynchronous replication plugin is installed. The number of times the source failed when calling time functions such as  gettimeofday() . This variable is available only if the source-side semisynchronous replication plugin is installed. The average time in microseconds the source waited for each transaction. This variable is available only if the source-side semisynchronous replication plugin is installed. The total time in microseconds the source waited for transactions. This variable is available only if the source-side semisynchronous replication plugin is installed. The total number of times the source waited for transactions. This variable is available only if the source-side semisynchronous replication plugin is installed. 964
