Editor’s NotesDateline: My Backyard, Edmonton, Alberta, Canada I’m surrounded by the green of spring on my patio. Wait, er, that was the last issue. In this issue we’re talking not about the green of spring but rather the spirit embodied in the steel, glass and concrete structures that rise up from a rocky island off the east coast of the U.S. It goes by many names: The City of Dreams, The City That Never Sleeps, The Capital of the World, Where Night Court Takes Place. Of course, I’m talking about New York City. I visit the home of Night Court pretty frequently, so it’s not that the city itself has me daydreaming, nor is it the abundance of floppy pizza contained therein, but rather the upcoming gathering at Redis Day New York that I’m looking forward to (sign up here). If you’re in easy distance of the Big Apple via train, plane or automobile, I suggest you check it out. You can meet me, an honor bestowed only upon the most elite of Redis Geeks. All this comes with the proviso that I’m upright and able to hydrate myself enough to make it out of the hotel (confused? See Redis Watch #74), Barring that, I’ll be there to hear about new stuff in the pipeline, exciting use cases, and of course whatever Mr. Salvatore Sanfilippo is cooking up. Happy Redising, Kyle Davis
Redis Trivia: 512mb is the limit to set a string in Redis. However, if you need more space and your string is non-binary, you can use RedisJSON (and JSON.SET) to store more than 512mb in a single string – you just have to put double quotes around it. Don’t go crazy though, it’s an expensive operation at this scale! |

StoriesDesign of new modules API functions: server events and module private dataWork on the Modules API moves forward and in this issue, Antirez discusses the implementation of new events that would notify modules of system-wide changes that could impact them. One example is notifying a module that another one was loaded, or that the server is about to shut down. These new additions will allow developers to build higher quality modules that behave better in the Redis ecosystem, making your friendly neighborhood module a real production-ready Avenger. Benchmarking the experimental Redis multi-threaded I/OFilipe Oliveria talks about what you can expect out of multi-threaded I/O in the upcoming releases of Redis. While I’m an event loop type of guy (single-thread forever), he makes a great case about network bounding. He makes some bold statements about being able to get above 50 mil ops/second threshold with a tiny number of servers but seem to be an in-theory calculation at this point. I’d love to see it in more than just theory. Just like the C train can get you from 168th to Euclid Ave in Brooklyn, amirite? Redis turned 10. 10 reasons why Redis is a great technologyEarly on, New York City was New Amsterdam, settled by the Dutch. So, I imagine that early Manhattan was ripe with windmills and littered with discarded wooden shoes and tulip bulbs [Editor’s note: I have never visited the Netherlands, so this is just my overactive imagination spoiled by years of stereotypes.] Anywho, if you made assumptions about the early history of Redis, head over to Eduonix for a pretty good historical overview our favorite in-memory NoSQL database and why you should use it. They also link to some courses by a friend of Redis, Brad Traversy. I haven’t done the course personally, but the course outline looks pretty good. Beating round-trip latency with Redis pipeliningEver get stuck on a train that is stuck behind another train…that’s behind another train? Ever run to catch a train to jump on it and sit down only to hear the conductor say, “we’re being held at the station for a bit.” This is life without Redis pipelines. Here’s a great small article that explains what pipelines are and how you can make use of them in Redis. A Fireside chat with Redis
Laravel response cache packageLike Starbucks in Brooklyn, Spatie is *everywhere* in the Laravel community. This is a great package that helps you cache full responses and gives you really good controls to tweak caching and decide what not to tweak. Getting started with RediSearch with WordPress and WooCommerce on UbuntuLike the dollar-slice of pizza on every corner, it feels like everyone is using WordPress somewhere in their organization. There are many flavors and tons of plugins. Can you use Redis with WordPress? Of course, you can! This is a great write up on a plugin that uses RediSearch. Learn how to get the module installed, loaded and activated with WordPress. One word of warning: you’ll need to install Redis on your server, it won’t install Redis for you. |

Libraries and ToolsA good-looking Redis text-based UI client written in Go. It’s not a REPL-like redis-cli, so it’s less powerful in a way, but makes up for it by allowing a more graphical view of Redis, without having to trade your keyboard for a mouse. It’s an early version, so you know the drill (be careful about using alpha tools in production), but it’s very promising.
I don’t follow sportsball, but it is very confusing to me that the New York Jets actually play in New Jersey. So, if you live in New York, you have to go to New Jersey to cheer for your hometown team. Messed up, man. This is similar to the npm-cache-proxy, which is written in Go. If you want to speed up Node(.js) Package Manager, you can use Go and, of course, Redis. I haven’t personally used it, but it seems like solid software to chance downloading half the internet when you try to get that React project going.
New York has that weird, floppy pizza that you have to turn into some sort of origami before you eat it or it falls into a droopy mess. Compare this to, say, Chicago, where pizza is a gut-bomb discus, and you might understand why people prefer something a little less heavyweight. This was the same idea behind mini_redis, a smaller, lighter weight (and, I assume, less greasy) version of a Redis client for the Crystal programming language. Check it out for your next Crystal project.
In early November of last year, the Big Apple was enthralled by a Mandarin duck that had somehow taken up residence in Central Park. I’m not sure it will draw the same crowds, but Wildduck is a “modern mail server software for IMAP and POP3” that looks pretty dang slick. The best part is that it uses lots of Redis. Check it out!

OverheardThat moment when your project (BlockHound) is trending on @github in “C” language, next to repos like Linux kernel, Git, Curl, Redis and others

RedisOur research says that a newsletter of this size takes about 8-9 minutes to read completely. By this point, you should be thoroughly in a New York state of mind. Was this some sort of subliminal messaging to get you to Redis Day New York? Of course it was, so
get your (free) tickets today. Also, it was much easier to write quips about the Big Apple than our last two themes (Editor’s note: what was I thinking?). Can’t make it to New York on June 26 and 27? Well, that’s what JFK, LaGuardia and Newark are for. What’s that? You can’t get a ticket? Have you considered the many Amtrack connections to Penn Station? Don’t like trains or planes and you’re in the UK? Well, have you considered Cunard’s Queen Mary 2 from Southampton to New York? There are so many options.
If one of those fine travel options doesn’t work for you, you can still catch up with Redis developments by looking at these articles by the good folks at Redis:
Finally, if you have free time on June 13th, then you should add this webinar to your series of activities for the day:
See you in New York! |
