Detailed Description

The class is a Rpl_filter representing global replication filters, with a vector that references all Rpl_pfs_filter objects used to represent P_S.replication_applier_global_filters table.

There is one instance, rpl_global_filter, created globally for replication global filter. The rpl_global_filter is created when the server is started, destroyed when the server is stopped.

Member Function Documentation

◆ get_filter_at_pos()

Rpl_pfs_filter * Rpl_global_filter::get_filter_at_pos ( uint  pos)

Used only by replication performance schema indices to get the global replication filter at the position 'pos' from the rpl_pfs_filter_vec vector.

Parameters
posthe index in the rpl_pfs_filter_vec vector.
Return values
Rpl_pfs_filterA pointer to a Rpl_pfs_filter, or NULL if it arrived the end of the rpl_pfs_filter_vec.

◆ get_filter_count()

uint Rpl_global_filter::get_filter_count ( )

Used only by replication performance schema indices to get the count of global replication filters.

Return values
thecount of global replication filters.

◆ operator=()

Rpl_global_filter & Rpl_global_filter::operator= ( const Rpl_global_filter info)
private

◆ reset_pfs_view()

void Rpl_global_filter::reset_pfs_view ( )

This member function is called every time the rules of the global replication filter are changed.

Once that happens the PFS view of global replication filter is recreated.
