zls VS tigerbeetle

There is no official documentation but the standard library provides definitions for the exchange format and an incomplete set of function for exchanging messages in Client.zig and Server.zig. You can find examples of the zig compile server in action in my PR for ZLS and a showcase of hot-code-swapping by kubkon. The code that implements the ZCS in the zig codebase can be found here.

Same experience here, I did file a bug about it too: https://github.com/zigtools/zls/issues/1139

Welcome to the word of new languages, I think rust just got an intellij plugin late last year and its been in 1.0 since 2015 (not to mention the years of hype around it). When it comes to "non standard" languages (meaning not the industries current go to for a given niche), it helps to assume there's no "It's just works" type editor support. Luckily most languages, even new ones have LSP servers including zig, and editors like VSCode make it pretty simple to use them.

For the people who come in the future and want to know how to do it, here is the code as of today (at some point it will be in ZLS repository - github.com/zigtools/zls - and you should take a look there too to see more up-to-date code).

Commands: git clone --recurse-submodules https://github.com/zigtools/zls cd zls zig build -Drelease-safe

> Building is slow. It takes about ~3 seconds minimum which is frustratingly slow when I'm fighting basic syntax errors. I wish there was a fast zig check.

> Lack of zig-analyzer makes learning hard.

> zig fmt src/main.zig is nice. Wish it automatically ran on all files.

I also did (well, "am doing", can only work a bit each day and am plugging through day 7 right now) AdventOfCode in Zig this year.

These points here didn't resonate with me at all. I wonder if the author knew about or tried ZLS[0]. I had it on and integrated with my VSCode and it would check a lot of things as I went and format on save. I think I followed something like this[1] to set it up.

I'm waiting for someone to implement the Redis API by swapping out the state machine in TigerBeetle (which was built modularly such that the state machine can be swapped out).

I fully agree with what Prime says at the end - Joran has really set a new bar here for all future database presentations.

Hearing that the entire TigerBeetle domain logic lives in a single file [0] (and is intended to be pluggable for other OLTP use cases!) makes it 1000% more tempting to spend the weekend getting up to speed with Zig.

Why would you want to build your own accounting ledger from scratch? Accounting is a completely new domain for most engineers, and TigerBeetle (https://tigerbeetle.com/) already solves this problem.

Maelstrom [1], a workbench for learning distributed systems from the creator of Jepsen, includes a simple (model-checked) implementation of Raft and an excellent tutorial on implementing it.

Raft is a simple algorithm, but as others have noted, the original paper includes many correctness details often brushed over in toy implementations. Furthermore, the fallibility of real-world hardware (handling memory/disk corruption and grey failures), the requirements of real-world systems with tight latency SLAs, and a need for things like flexible quorum/dynamic cluster membership make implementing it for production a long and daunting task. The commit history of etcd and hashicorp/raft, likely the two most battle-tested open source implementations of raft that still surface correctness bugs on the regular tell you all you need to know.

The tigerbeetle team talks in detail about the real-world aspects of distributed systems on imperfect hardware/non-abstracted system models, and why they chose viewstamp replication, which predates Paxos but looks more like Raft.

> There is no reason to use a memory unsafe language anymore, except legacy codebases, and that is also slowly but surely diminishing. I'm still yet to hear this amazingly compelling reason that you just need memory unsafe languages. In terms of cost/benefits analysis, memory unsafety is literally all costs.

Tell that to the authors of new memory unsafe languages (like Zig) and creators of new project in those languages (like https://tigerbeetle.com) :(
