virtual bool Rpl_info::set_info_search_keys ( Rpl_info_handler to)

To search in the slave repositories, each slave info object (mi, rli or worker) should use a primary key.

This function sets the field values of the slave info objects with the search information, which is nothing but PK in mysql slave info tables. Ex: field_value[23]="channel_name" in the master info object.

Currently, used only for TABLE repository.

Implemented in Relay_log_info, Slave_worker, and Master_info.

◆ set_rpl_info_handler()
