In Part One of this series, I discussed what a monorepo is, defined contextual repos, and covered a review of a couple articles which attempted to illustrate the benefits of a monorepo. In this part, I’m going to go a bit deeper into some of the assertions I made, and some claims often made “in defense of” monorepos.
There is a wave of argument growing among how to organize software repositories
; the god-repo (commonly known as a monorepo) and focused repositories. By
and large there is no one best way. Rather it is a question of which yaks you
want to shave. This is a meager attempt to explore them without a general
recommendation.
If you’re a programmer you’ve likely heard or read someone expound the benefits and advantages of typed code. Things like compile-time validation that you are passing an integer rather than a string, or avoiding variable type overloading, speed, and many more. However, sometimes this can lead to better code in programs other than the one you’re writing in a statically typed language.
Everything doesn’t have to be asynchronous and sometimes making something asynchronous leads to problems. The following rules and guidelines should help you minimize those problems and make proper use of asynchronous calling.
While Salvatore and I have discussed some significant changes to various aspects of Sentinel, enough to likely warrant a Sentinel version change, I wanted to capture some of the more incremental proposals we talked about during this year’s #redislondon dev day.
Redis already has one of the most extensive set of configuration options available to any data store. But we can do better. I proposed these changes at the Redis Developer Day 2015 in London this week but this is the greater detail version.
Sentinel configuration and configuration management systems don’t play well together, and neither do package management systems and the config file. As a result it is possible to have your sentinel configuration file wiped clean under a running sentinel. Here are some ways you might be able to recover your running configuration.
A little-known ability of Redis’ Sentinel mode is event based “script” execution. When so configured, Redis can call an external executable file on certain events, passing the event information on to the command. This is useful for monitoring as well as reconfiguration events. Eventilator is a small utility I’ve written to make this process easier.
Sometimes you need or want to connect to a Sentinel managed Redis master but would rather not manually pull the connection information from the config or API, then run redis-cli with the current information. Now you can do it easily.
In the first of this mini-series on Clustering Redis I mentioned Codis as one of the projects doing this for you. In this installment I’m going into more detail on Codis. The authors of the project have made some interesting choices, and these choices make Codis different with different requirements and implications than some of the others.
