Do stored procedures get replicated?
A stored procedure that is executed on the master that updates replicated data is a replicated stored procedure. Under the default replication mode, the stored procedure CALL statement is replayed on the subordinate by using by-SQL replication; the execution of the stored procedure is not replicated.
What is master-slave replication model?
Replication Overview. Master-slave replication enables data from one database server (the master) to be replicated to one or more other database servers (the slaves). The master logs the updates, which then ripple through to the slaves. In this environment, all writes and updates must take place on the master server.
Can we replicate stored procedure in SQL Server?
Only the replication stored procedures documented in SQL Server Books Online are supported. Undocumented stored procedures are only for the use of internal replication components and should not be used to administer replication.
How does master slave replication work in MySQL?
The master slave replication process enables database administrators to replicate or copy data stored in more than one server simultaneously. This helps the database administrator to create a live backup of the database all the time.
How does MySQL trigger and stored procedure replication work?
According to the MySQL docs, for replication triggers log the call to the trigger while stored procedures actually log the result of the stored procedure. So my question is, when my trigger gets fired, will it replicate both the trigger and the results of the procedure that the trigger calls (resulting in the procedure effectively being run twice)?
Why do I need a slave in MySQL?
The slaves can also be used for data accessibility to reduce the load on the master database. One of the main purposes of going for a master-slave replication system is to have a standby system with a live backup that can be promoted as the master when the original master server crashes.
Can a single master write to multiple slaves?
You can have a single master and multiple slaves or multiple masters and multiple slaves, etc. In this process, it is always a single or one-way transmission of data. The data is stored in the master first and then copied on to the slaves. Hence, the write operation is performed only on the master database.
