Detailed Description

Structure to hold parameters for CHANGE MASTER, START SLAVE, and STOP SLAVE.

Remark: this should not be confused with Master_info (and perhaps would better be renamed to st_lex_replication_info). Some fields, e.g., delay, are saved in Relay_log_info, not in Master_info.

◆ anonymous enum

anonymous enum

Identifies what is the slave policy on primary keys in tables.

If set to STREAM it just replicates the value of sql_require_primary_key. If set to ON it fails when the source tries to replicate a table creation or alter operation that does not have a primary key. If set to OFF it does not enforce any policies on the channel for primary keys.
