MySQL 8.0 and newer change and improve how we measure and monitor replication lag. Even though multi-threaded replication (MTR) has been on by default for the last three years (since v8.0.27 released October 2021), the industry has been steeped in single-threaded replication for nearly 30 years. As a result, replication lag with MTR is a complicated topic because it depends on version, configuration, and more. This three-part series provides a detailed understanding, starting from what was originally an unrelated feature: binary log group commit.

It’s very difficult explaining to students new to relational databases how SQL works. There are many parts that seem intuitive and then there are others that confuse and confound.

For beginners, the idea that a SQL statement is simply a text string that you must dispatch to a SQL statement processing engine is new. That’s because they use an Integrated Development Environment (IDE) that hides, or abstracts the complexity, of how SQL executes.

I start my core SQL class by demonstrating how to run a text literal query without a FROM clause in MySQL Workbench, like this:

SELECT 'Hello World!' AS "Output";

After writing the query, I highlight everything except the semicolon and click the lightening bolt that dispatches the static string to the SQL statement engine. They see this result:

Then, I launch a mysql Monitor session and write the query with a semicolon to dispatch the SQL …

Instead of having MySQL Servers discarding changes, the NDB data nodes do such work for them saving computing resources for the whole cluster.

You can connect to MySQL Server using MySQL Client (the command-line utility) and GUI tools. This article will review each method in detail.
