Replication is dead, long live Replication!

Brian Aker has found general agreement with his post: "The Death of Read Replication".

Arjen Lentz says "I think Brian is right...", and Frank Mash confirmed: "what Brian says about replication, caching and memcached is very true".

Just like Video killed the Radio Star it looks like maybe Memcached killed the Replication Hierarchy!

But of course, Brian and others are talking about replication for scaling reads.

In my session on PBXT next week at the conference I will be talking about how we plan to use synchronous replication to produce an HA solution for MySQL at the engine level.

I will also discuss how some flexibility in the PBXT architecture makes it possible to actually scale writes efficiently as mentioned by Arjen in his blog.

So don't miss it:

High Performance MySQL, Second Edition: Replication, Scaling and High Availability

Continuing in the tradition, which I hope has been as helpful to you as it has been to me, I'm opening the floor for suggestions on chapter 9 of the upcoming High Performance MySQL, Second Edition. Unlike the other chapters for which I've listed outlines, this one isn't substantially written yet. It's in detailed outline form at this point (a tactic that has worked very well for us so far -- I'll write about that someday).

I'm trying to get feedback much earlier in this chapter's lifecycle, for several reasons. Two of the most important are that this is one of the first chapters I've had a chance to really take from scratch, and the chapters I haven't written from scratch have been harder to organize, as you've probably seen from the last few outlines I posted. There's a lot of value in working top-down on this deep encyclopedia-style material.

Read on for the outline and more thoughts I just can't keep to myself.

conntrack-tools: userspace tools for manging conntrack-state for high availability

The conntrack-tools are the userspace daemon so-called conntrackd and a command line interface known as conntrack. Both tools let system administrators interact with the Netfilter Connection Tracking System from userspace.
