As you know, one of the most eagerly waited features was released with MySQL 8.2: the transparent read/write splitting.

In this post, we’ll look at how to use it with MySQL-Connector/Python.

Architecture

To play with our Python program, we will use an InnoDB Cluster.

This is an overview of the cluster in MySQL Shell:

JS > cluster.status()
{
    "clusterName": "fred", 
    "defaultReplicaSet": {
        "name": "default",

In Alan Beaulieu’s wonderful book Learning SQL: Generate, Manipulate, and Retrieve Data, he uses a SQL 1 to demonstrates a CROSS JOIN in MySQL counting from 1 to 100. My students always find it difficult to read because the subqueries take so much space it makes it difficult to see the process, for example he gives this SQL 1 solution:

SELECT ones.x + tens.x + 1 AS counter
FROM
 (SELECT 0 AS x UNION ALL
  SELECT 1 AS x UNION ALL
  SELECT 2 AS x UNION ALL
  SELECT 3 AS x UNION ALL
  SELECT 4 AS x UNION ALL
  SELECT 5 AS x UNION ALL
  SELECT 6 AS x UNION ALL
  SELECT 7 AS x UNION ALL
  SELECT 8 AS x UNION ALL
  SELECT 9 AS x ) ones CROSS JOIN
 (SELECT 0 AS x UNION ALL
  SELECT 10 AS x UNION ALL
  SELECT 20 AS x UNION ALL
  SELECT 30 AS x UNION ALL
  SELECT 40 AS x UNION ALL
  SELECT 50 AS x UNION ALL
  SELECT 60 AS x UNION ALL
  SELECT 70 AS x UNION ALL
  SELECT 80 AS x UNION ALL
  SELECT 90 AS x ) tens
ORDER BY counter;
