Hi, I have started some explorations for durable persitent indices in a cross-platform fashion, that I wanted to for quite some time now. There are some other implementations of persistent datastructures with synchronous IO on the JVM, but I would like to go a step further and generalize over any key-value store like medium. I am primarily interested in critique and references to other work or experience implementing efficient indices on disk. In the longer run I want to use these indices as a building block for databases in Clojure(Script).
https://github.com/replikativ/durable-persistence >From the README: This repository is for exploration of persistent datastructures on a durable medium. The durable medium is abstracted away by a minimalistic key-value protocol providing atomic operations (ACID) on single keys. This decouples the implementation of the persistent datastructure from the host and backend store. The repository contains an adaptation of the cookbook in-memory version of a red black tree. Instead of keeping all fragments in memory we introduce a Reference type to fragments in the store and dynamically load and store fragments. The root can be assigned to a fixed key, modelling a durable identity similar to a Clojure atom. The long term motivation is to provide efficient indices as a building block for datatype management independent of JVM IO libraries spanning also to ClojureScript and the Browser. With konserve an IndexedDB storage backend for the Browser already exists. For this reason IO should happen asynchronously through core.async in konserve. A durable Index for DataScript would be nice :).
