The smell of chlorine, sweaty smilodon, and hot plastic. Ah, summer. If only there was another cold drink…

That raft was a promotional item for two and a half children, it’s a bit snug for a two-meter cyborg who hasn’t lost his winter weight…

A minimal distributed key-value database with HashiCorp's Raft library

HashiCorp의 Raft 라이브러리를 활용해 단일 파일로 구현한 최소 분산 키-값 데이터베이스 예제를 소개합니다. 이 데이터베이스는 키 설정과 덮어쓰기를 지원하며, HTTP API를 통해 클러스터 관리와 키-값 저장 기능을 제공합니다. Raft 알고리즘을 이용해 내구성을 보장하는 append-only 로그를 기반으로 각 노드가 메모리 내 상태를 동기화합니다. 스냅샷 기능은 구현하지 않았으나, Raft의 기본 복제 및 복구 메커니즘을 활용해 간단한 분산 상태 머신을 구축하는 방법을 상세히 설명합니다.

Taking Control of the SQLite WAL

rqlite 10버전은 SQLite의 Write-Ahead Log(WAL)를 직접 제어하여 Raft 기반 분산 데이터베이스의 스냅샷 효율성을 크게 개선했다. 기존에는 전체 데이터베이스 복사로 비효율적이었으나, WAL을 활용해 변경분만 스냅샷하고, 체크포인트 시점을 rqlite가 직접 관리한다. 또한, WAL 체크포인트 실패 시 다양한 상태를 감지해 적절히 처리하며, 느린 리더로 인한 스냅샷 지연 문제도 최소화했다. 이로써 대용량 데이터베이스에서도 빠르고 일관된 스냅샷이 가능해졌다.

I'm having complicated feelings about #Raft .

Playing through the quest has been a very mixed time. For a game that is ostensibly open world survival, all of the story islands are truly puzzle platformers. I'm a fan of puzzle platformers! But I feel like the designs have been very uneven, with some areas a joy to play, while others are an unintuitive slog.

That said, I'm two scenes away from beating the last level, and it's... ridiculous? In the next-to-last scene, you have to build a stairwell out of crates in a small arena while three hyenas attack you and a madman wings cherry bombs at your head.

And, in normal mode (which I'm playing), you lose 2/3rds of your stuff whenever you die, and the save history is completely non-functional - you can't go back to a previous save and try again.

Naturally, I died very quickly, and lost some very important equipment.

So, I sat on it for a few days to determine whether I should give up or power through - where powering through meant another 10-20 hours working on upgrades and better equipment.

Which is what I decided to do.

But a key piece of equipment is healing salve, which requires eggs, which requires chickens (cluckers, in game)

Which is why I now have a poultry pen on my raft, populated by the first chicken of my set
