How to trigger events in row based master-slave?
I inserted the trigger on the Slave server (not on the Master because I am using row-based replication). The process checks the “Ins_table” every 10 seconds to obtain new records. The replication happens perfectly fine. However, the trigger on the slave-side never works.
When do triggers activate in MySQL do they activate?
MySQL triggers activate only for changes made to tables by SQL statements. This includes changes to base tables that underlie updatable views. Triggers do not activate for changes to tables made by APIs that do not transmit SQL statements to the MySQL Server. This means that triggers are not activated by updates made…
What are the restrictions on triggers in MySQL 5.6?
For answers to commonly asked questions regarding triggers in MySQL, see Section A.5, “MySQL 5.6 FAQ: Triggers” . There are some restrictions on the use of triggers; see Section 20.8, “Restrictions on Stored Programs” . Binary logging for triggers takes place as described in Section 20.7, “Stored Program Binary Logging” .
Do You need Statement based replication for slave side triggers?
If you want triggers to execute on both the master and the slave—perhaps because you have different triggers on the master and slave—you must use statement-based replication. However, to enable slave-side triggers, it is not necessary to use statement-based replication exclusively.
Why does MySQL replication not support multiple triggers?
If an upgraded replication source server still has old replicas using MySQL versions that do not support multiple triggers, an error occurs on those replicas if a trigger is created on the source for a table that already has a trigger with the same trigger event and action time. Downgrades.
Why is statement based replication unsafe in MySQL 8.0?
A statement invoking a trigger (or function) that causes an update to an AUTO_INCREMENT column is not replicated correctly using statement-based replication. MySQL 8.0 marks such statements as unsafe. (Bug #45677)
