Go-Hit

This is a KV-store tool implemented in Go.

Simple objective: To make a tool which is super scalable, fast, can handle tons of data for scalability.

To start the server:

go run cmd/go-hit-server/main.go

Simple objective of this is to create the best of all worlds like solution that can support multiple backend storage. Also, it should be concurrent in nature.

Why do we need this?

• Easy to digest, fast to read and fault tolerant to restart.
• Can support 100k writes a second and data reload (on restart) should be atleast as fast as 100k read per sec. Note that we are just talking about a simple benchmark of write a {"key":"value"} no matter how we store in rdbms, nosql, file storage, etc.
