Galvanize This: Hanging Out with Redis

So, I attended a Redis workshop a few days ago, at the New York “campus” (which is a buzzy, DB-esque industry word that I loathe) of Galvanize. Even though I usually don’t go for these meetup/workspace type of places, I’ll admit that this one was rather pleasant. Unlike other places, it did a good job of finding that fine line between casual and professional. For example, no beanbags anywhere. Because as much as I love beanbags myself (i.e., I have two at home), we can’t look at your screen together unless I get on my knees or I crawl onto the beanbag with you…which might be uncomfortable in many ways for the both of us. Plus, the space had reliable WiFi for most of the time I was there, unlike some other places.

Even though I’ve already been dealing with Redis at work for a little while now and generally impressed with its performance, it never hurts to try and learn something from the masters. (Unfortunately, AntiRez himself did not leave Sicily and fly over to teach us.) I was curious how they were going to showcase the tech and if we were going to just sit there and watch, when they instructed us to download Docker. As it turned out, we were going to learn the lesson via containers with Jupyter Notebooks, which I had never heard of before. And since I yearn for the era of interactive documentation, I couldn’t have been happier. (On a side note, I only recently learned about KataCoda, which I love just as much, if not more.)

Even though the second half of the day was your familiar salespitch for Redis Enterprise and Redis Cloud (which did seem to be an appealing purchase), the first half of the day was when they taught about the product itself. For the most part, it wasn’t anything new to me, aside from the occasional bit of trivia. (Lua is the language used by the Redis CLI? Huh. It’s come a long way since being just the scripting language for WoW skins.) I did learn a few tidbits about the data structures (like the existence of HyperLogLog), but since I use Spring Caching in our microservices, we don’t pay that much attention to them.

Instead, it was interesting to learn about the features of Redis that we weren’t even leveraging yet at work. For example, you can write your own extensions to Redis using C. Which I’d be tempted to do just because, since I miss writing in C…Also, it was interesting to learn about the various modules that were already available for Redis, with functionality ranging from machine learning to bloom filters. And that’s when I recognized a pattern seen before. Much like every other tech company, there seems to be the desire to get into whatever is hot, to survive as a company by being more horizontal. However, I would implore Redis to be careful and to never neglect your core mission. I, for one, don’t really need machine learning, but I’d like Redis to work with Spring (i.e., Pivotal) to further develop the Spring Data Redis layer and make it configurable, so I can easily direct reads to slave nodes. I need that, not machine learning. So, even though I didn’t learn a great deal about Redis by attending, I got to see the general direction of the company. In that way, I’d say that the trip to Galvanize was worth it.

That, and spears of fresh fruit.

You just can’t argue with fresh fruit spears, where the fruit is cut into various geometrical shapes. It just plucks the right strings of geeky hearts.
