If you just want to learn the language, read scala for the impatient, first half is free on Lightbend's website. If you want to learn fp, read functional programming in scala (Manning).

It's been over 12 years since Scala 1.0. I've been doing Scala full time for 7 years. It's not new and shiny.

Surely it has nothing to do with the buyers of our goods and services insisting that the problem they need solving is unique, so trivial it should be done yesterday, and so clear that they dont really need detailed written specifications?

A Java "death", where it becomes one of the most popular programming languages in industry? Rust should be so lucky.

If all the connections in the pool are taken, then the database wouldn't have been getting meaningful additional work done anyway, regardless of your scheme for accepting connections. Having 100-1000x more active connections than you h

Theo deRaadt complaining about "copyright theft" is hilarious given his original stance on the ipfilter debacle.

I've been working on a PoC using Citus for the past month or so. Craig and the devs there have been super responsive in making sure our technical needs get met. The core open source product already seems like the best sharded relation

I've managed a production kafka cluster at my current gig for over two years. It has been easy and trouble free with the exception of one incident, which was ultimately our fault.

Hutton's book is more concise and written better. From first principles covers slightly more material, at the expense of being 4 times longer.

Sorry, but there's no way scalaz is a more popular library than Spark.

None of the stores I mentioned use mysql. I'm not talking about scaling mysql, I'm talking about scaling relational databases, specifically the comment about joins. Joins arent a big deal, just join on (at least) the shard key, or

by kod 10y ago
Joins are still possible in sharded relational models. I wouldn't want to roll my own on mysql, but there are plenty of data stores that use this model (vertica, citus, etc)

They absolutely are faster, because there are optimizations available on data frames that are impossible on RDDs. Pushdown is the most obvious one. If I don't know what data store is underlying your RDD, I don't know your schema,
261.
by kod 10y ago
RDDs are not obsolete. The reason dataframes are faster is exactly because they are more restrictive than RDDs. If you need to run arbitrary code, RDDs are stil more flexible.

Multiply the number of updates times the number of indexes. Then consider that with such a small table, there's going to be contention for the same rows. Updates actually create new rows, so vacuum needs to be able to remove older, no

If nothing else, I could teach you that zeromq has nothing to do with queing or durability. It's certainly possible that Rabbit has improved in the years since I used it, if it works for your use cases, great. But don't assume tha

Yeah, you recommended a sockets library as an alternative to a distributed durable circular buffer. Not obviously clueful. Might as well recommend Nginx as an alternative to JavaScript. I need to durably handle billions of events per day. N

I've used Rabbitmq, it most certainly does not fulfill the volume requirements I have. The fact that you are comparing zeromq to Kafka is pretty good evidence that you have no idea what you are talking about, and are just tossing out n

Many out there that scale like Kafka, so surely you can name some? Yes, zookeeper is a turd, but it's a battle tested turd. Distributed systems aren't easy to get right.

I'd love to hear why Kafka is not good software, and what open source alternatives are available that scale the way it does.

Or perhaps they dropped it because Java 6 was end-of-life 3 years ago.

Java EE can die in a fire. Only thing that matters at this point is that the JVM stays relevant.
