tigerbeetle VS Spring

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) :(

1. Spring Framework The Spring Framework is a popular Java framework used for building enterprise-level applications. This repository contains the source code for the framework and related projects such as Spring Boot and Spring Security. https://github.com/spring-projects/spring-framework

This interface is a simplified version of real caching abstractions from Java technologies such as the ones from Spring or JCache (JSR-107). Both are part of quite complex solutions, having more generic types and different capabilities. Also, annotations would be preferred to using Cache directly in most Java applications.

Mitre really lost a lot of respect with CVE-2016-1000027. Every few weeks a warning that any SpringBoot 2.x project has a CVSS 9.8, which causes all sorts of heartache for those of us bound to CVE remediation. Every blasted security tool reports this one. Spring reviewed and rejected, as did our very, very large organization. Comically, this has become the CVE we use to see how our tools allow us to white/black list entries.

Thank god Spring dropped this interface in the Framework 6.x / Boot 3.x release, and the end for non-commercial support is this year for the old stuff.

Referring to https://github.com/spring-projects/spring-framework/blob/main/spring-web/src/main/java/org/springframework/web/bind/annotation/GetMapping.java, the value could have got assigned to any of the other members like name, path, params, etc. Is there any logic involved that enables the single value passed to the GetMapping annotation to be assigned to the value member?

This one. In short, JMS listeners stopped working randomly (of course only on Saturdays, and only under load), but at first we didn't know that and suspected the message broker at fault. We had quite extensive logging, but no observability on the broker. Can't remember all the details, but eventually we figured out it was the listener container, and I could reproduce it after debugging deeply into Spring code during a load test.

It still has, but it is more of "imaginary" one (https://github.com/spring-projects/spring-framework/issues/24434).
