Detailed Description

The class Rpl_filter_statistics encapsulates the following three statistics of replication filter: The configured_by indicates that how the rpl filter is configured.

The active_since indicates when the configuration took place. The counter indicates the hit amount of the filter since last configuration. Instances of this class are created in Rpl_filter for each filter type for each channel and the global filter, and have the same life cycle as the instance of Rpl_filter. The reference of this class is used in Rpl_pfs_filter for displaying the three statistics of replication filter in performance_schema.replication_applier_filters table and performance_schema.replication_applier_global_filters table.
