This is a follow-up for MySQL GTID tags and binlog events, but you don’t need to read that first.

One of the recent innovations in MySQL was the addition of Tagged GTID’s. These tagged GTID’s take the format of <uuid>:<tag>:<transaction_id>.

And this change means that the GTID_LOG_EVENT’s in the binary logs needed to be changed. The MySQL team at Oracle decided to not change the existing format, but introduce a new event: GTID_TAGGED_LOG_EVENT.

Initially I assumed that decoding the new event would me mostly identical to the original event, but with just a single field added. But this isn’t the case as Oracle MySQL deciced to use a new serialization format (Yes, more innovation) and use it for this new event. The new serialization format is documented …

Introduction

Query Attributes are a relatively new feature of the MySQL Protocol. This is availble since MySQL 8.0.23.

Before Query Attributes were introduced there already was already another similar feature: Connetion Attributes, which provides per-connection metadata in the form of key/value pairs.

This is what connection attributes look like:

mysql> SELECT ATTR_NAME, ATTR_VALUE
    -> FROM performance_schema.session_connect_attrs
    -> WHERE PROCESSLIST_ID=64;

As we know, Orchestrator is a MySQL high availability and replication management tool that aids in managing farms of MySQL servers. In this blog post, we discuss how to make the Orchestrator (which manages MySQL) itself fault-tolerant and highly available. When considering HA for the Orchestrator one of the popular choices will be using the Raft consensus. […]
