Well, we are almost there.

Percona Live 2021 is just around the corner and this year comes with a very “dense” agenda.  

From my side I am giving a speech that is a high-level comparison between PXC and PS with group replication as highly available solutions.

It is a bit new for me to be at such high level, given I prefer to dig into technical, but I also think it was worth to stop and have the chance better understand what gives us what.

Anyhow this blog is not about that.

Given, as said, this year we will have a very “dense” schedule, I initially look at it and get scared.

“Too much stuff!”, that was my initial thought. Then I take a breath, reserve a couple of hours of my personal time, and start to dig-in.

Just last week we had a Galera Cluster for MySQL streaming replication feature deep dive webinar, by the person that implemented it – Seppo Jaakola. In fact, if you haven’t already read the entire story, we encourage you to read: Galera Streaming Replication: Too Big A Bite Can Choke Your Cluster. We also have the 60 minute video recording for reference.

A huge number of Galera Cluster users have always complained about having issues with large transactions (where writes hang but reads are OK), and we are certain that the correct usage of streaming replication is what will ease that burden. What constitutes a large transaction? Typically when you make big number of …

Introduction

In my previous two blogs on this topic I first introduced the concept of automatic thread configuration and the thread model we use in RonDB. After receiving some questions on the topic I dived a bit deeper into explaining the RonDB thread model and its thread pipeline and compared it to another similar concept called batch pipelines.

Since then I read up a bit more on the research in this area with a focus on implementations in other key-value stores. Some researchers argue that a model where one handles the request immediately is superior to a model using a thread pipeline.
