Show HN: Piladb – A lightweight RESTful database based on stack data structures
github.comI am wondering what is the use case for this and how is this different from Redis set commands (LPOP,RPOP, etc)
This is a good question, that needs to be better addressed in the documentation.
piladb can have multiple use cases, but I'm mostly thinking on in-memory caching, keeping multiple versions of the cached resource (elements in the stack), and managing invalidation with the provided dates. It can be used as a key-value store, where the key is the name of the Stack, and the value is the Peek, and yet you can keep previous versions of this one. And it can be also used for pretty much any problem where a classic stack data structure can help, only that it is running as a lightweight http server.
The main difference with Redis lies in the scope and in many operational aspects. About the former, Redis provides all kind of data structures, whereas piladb only aims to provide stack data structures as a service, and do it right. Regarding operational issues, piladb is extremely easy to deploy (just a binary, no config files), and any HTTP client is a piladb client, no need for protocol implementations.
Last but not least, piladb provides a comprehensive Go library to implement embedded stacks inside Go programs.
Said this, this never aimed to be a Redis killer, Redis is an amazing project, and a huge inspiration to develop piladb.
