MySQL Replication Quiz

Study Notes

MySQL Replication Topology

MySQL replication commonly utilizes a master-slave topology.
In this setup, the master server processes write operations, while slave servers replicate the master's data and handle read queries.

Function of the Master Server

The master server is responsible for writing data and handling all data modifications.
It records changes to the binary log, which serves as a transaction log for replication.

Role of the Slave Server

The slave server replicates the master server's binary log and applies changes to its own database.
It provides a way to balance load by handling read queries, improving application performance.

MySQL Statement Group

A group of MySQL statements executed together is known as a transaction.
Transactions ensure data integrity and allow for rollback in case of errors.

Result of a MySQL Transaction

Upon successful completion, a MySQL transaction permanently saves changes to the database.
If a transaction fails, the system can roll back to the last committed state, maintaining consistency.

Purpose of a MySQL Statement Group

The primary purpose is to ensure that a series of operations either complete fully or not at all, maintaining data integrity.
Transactions are critical in scenarios where multiple related changes must succeed together, such as transferring funds in banking systems.
