It only updates usage data if the feature is enabled.

Parameters

enabled

true: tracks as enabled false: tracks as disabled

track_replication_replica()

void Rpl_opt_tracker::track_replication_replica

(

bool

enabled

)

Tracks the Replication Replica feature, including the usage data.

It only updates usage data if the feature is enabled.

Parameters

enabled

true: tracks as enabled false: tracks as disabled

track_replication_replica_internal()

void Rpl_opt_tracker::track_replication_replica_internal ( bool  enabled )

private

Tracks the Replication Replica feature, including the usage data.

It only updates usage data if the feature is enabled. Internal method to be used after the mysql_option_tracker_option service is acquired.

Parameters

enabled
