MySQL Memory Consumption and Open Prepare Statements

Today I read the nice post of Bhuvanesh on the memory leak issue they experienced with MySQL. In fact when you read the post, you realize that MySQL was just following the parameters that were setup (the default of max_prepare_stmt_count is 16382 even on 5.6).

I’m still convinced that the problem should be resolved in the application even if the use of ProxySQL for multiplexing is great.

In MySQL 8.0, we have enabled the …

Review of TRIAD: Creating Synergies Between Memory, Disk and Log in Log Structured Key-Value Stores

This is review of TRIAD which was published in USENIX ATC 2017. It explains how to reduce write amplification for RocksDB leveled compaction although the ideas are useful for many LSM implementations. I share a review here because the paper has good ideas. It isn't easy to keep up with all of the LSM research, even when limiting the search to papers that reference RocksDB, and I didn't notice this paper until recently.

TRIAD reduces write amplification for an LSM with leveled compaction and with a variety of workloads gets up to 193% more throughput, up to 4X less write amplification and spends up to 77% less time doing compaction and flush. Per the …

Updated: Doctrine and MySQL 8 - An Odd Connection Refused Error

I am currently working my way through the many PHP Frameworks to see how they get on with MySQL 8.  The Frameworks that can take advantage of the MySQL Improved Extension or mysqli can take advantage of the SHA256 Caching Authentication method. But those that are PDO based need to use the older MySQL Native Authentication method.

I wanted to check the PDO based frameworks and today I just happened to be wearing the very nice Symfony shirt I received as part of my presentation at Symfony USA.  So I started with a fresh install of Symfony.  All was going well until it came time to get it to work with MySQL 8 through Doctrine.

Doctrine
Symfony uses Doctrine as an ORM (Object Relational Mapper) and DBAL  (Database Abstraction Layer) as an intermediary to the database.  While I myself am not a big fan of ORMs …

Design A Highly Available MySQL Clusters With Orchestrator And ProxySQL In GCP — Part 2

Design A Highly Available MySQL Clusters With Orchestrator And ProxySQL In GCP — Part 2

In part1, we explained how we are going to approach the HA setup. Here we can see how to install and configure Orchestrator and ProxySQL, then do the failover testing.

Install and configure MySQL Replication:

We need a MySQL with 4 Read replica and the 4'th replica will have a replica for it. And we must have to use GTID replication. Because once the master failover done, the remaining replicas will start replicating from the new master. Without GTID its not possible, but as an alternate Orchestrator provides Pseudo-GTID.
