GitHub - jakekgrog/GhostDB: GhostDB is a distributed, in-memory, general purpose key-value data store that delivers microsecond performance at any scale.
GhostDB stemmed from a University project. Due to the nature of these projects (time constraints etc.), we feel some corners were cut. For example, we opted for the memcached model of distribution to save on time as it was easier to implement. However, this wasn't the original vision of GhostDB. Myself and Connor also started new jobs and these took up a good chunk of our time. This combined with

FoundationDB: A Distributed Key-Value Store – Communications of the ACM
FoundationDB is an open-source transactional key-value store created more than 10 years ago. It is one of the first systems to combine the flexibility and scalability of NoSQL architectures with the power of ACID transactions. FoundationDB adopts an unbundled architecture that decouples an in-memory transaction management system, a distributed storage system, and a built-in distributed configurati

Introducing Pebble: A RocksDB-inspired key-value store written in Go
Introducing Pebble: A RocksDB-inspired key-value store written in Go Since its inception, CockroachDB has relied on RocksDB as its key-value storage engine. The choice of RocksDB has served us well. RocksDB is battle tested, highly performant, and comes with a rich feature set. We’re big fans of RocksDB and we frequently sing its praises when asked why we didn’t choose another storage engine.

key-value storeを設計するにあたって,リカバリのためにwalを設計するとします。walを可変長にしたい場合,各wal recordにrecord長を表すheaderをつけるような実装が素直な実装の一つとしてあると思うのですが,wal recordを格納しているファイルが破損し,あるwal recordのheader部分が信頼できなくなった場合,各recordの長さがわからなくなってしまうため当該wal record以降のすべてのwal recordが信頼できなくなるような弱点があるように思えるのですが,この問題はうまく回避できるのでしょうか 前提として世の中にあるデータベースは基本的にログファイルが破損する事を想定していません。ログは信頼できるストレージに複製込で保存されており、化けたり消えたりする事はないという前提を置いています。想定する一番大きな障害でもMedia Fai

A minimal distributed key-value database with Hashicorp's Raft library | notes.eatonphil.com
A minimal distributed key-value database with Hashicorp's Raft library When I wrote the "build a distributed PostgreSQL proof of concept" post I first had to figure out how to use Hashicorp's Raft implementation. There weren't any examples I could find in the Hashicorp repo itself. And the only example I could find was Philip O'Toole's hraftd. It's great! However, I have a hard time following mult

InfoQ Software Architects' Newsletter A monthly overview of things you need to know as an architect or aspiring architects. View an example
We are in the arena ? Before we begin, we can ask some additional questions like: Q1. Does the data persist after the interactive shell session ends? Q2. Do operations on the data reflect to the global shell? Q3. Does COMMITing changes in a nested transaction reflect to grandparents as well? Your questions may differ, which is perfect. The more questions you ask the better you understand the probl
