In this article you will see how to use MySQL 8.2 transparent read/write splitting using MySQL Connector/Python and a MySQL InnoDB Cluster
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",
"primary": "127.0.0.1:3310",
"ssl": "REQUIRED",
"status": "OK",
"statusText": "Cluster is ONLINE and can tolerate up to ONE failure.",
"topology": {
"127.0.0.1:3310": {
"address": "127.0.0.1:3310",
"memberRole": "PRIMARY", …With the release of Percona XtraBackup 8.0.34-39, Percona XtraBackup (PXB) allows a backup on server version 8.0.35 and higher. We have removed the server version check because the MySQL 8.0 series has transitioned to bug fixes.
A feature change in the MySQL 8.0 series, such as the redo log record structure, could cause PXB to fail when taking a backup. To ensure a valid backup, use a PXB version equal to or higher than your source server version. Complete the process and prepare and restore your backups regularly. Do not assume that, because you have no error messages, that the backup ran successfully.
Before the backup starts, PXB checks the source server version to the PXB version to prevent a failed or corrupted backup due to source server changes. Percona XtraBackup 8.0.22 added the …

[Read more]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;

Vitess 18 is now Generally Available, with a number of new enhancements designed to improve usability, performance and MySQL compatibility. MySQL Compatibility Improvements # Foreign Keys # In the past, foreign keys had to be managed outside Vitess. This was a significant blocker for adoption. We are now able to support Vitess-managed foreign keys within the same shard. This includes the ability to import data into Vitess from an existing MySQL database with foreign keys.
The MySQL Protocol is the network protocol that is used between a MySQL server and a client. This is called the “classic” protocol as there is now a newer protobuf based protocol called X Protocol. However the “classic” protocol is used by many database drivers, applications, etc. and also by MySQL Replication.
The MySQL Protocol has the option to compress network traffic. Most client libraries don’t enable this by default as this increases CPU usage.
Some history
Initially this was added in MySQL 3.22 (based on historical release notes) and was based on zlib.
Then in MySQL 8.0.18 a …
