ImmuDB log API

Task description

The goal is to write a simple REST or GRPC service in Golang that uses immudb as a database to store lines of logs. Service and immudb should be easily deployable using docker, docker-compose or similar. There should be another simple testing tool that allows you to easily create log entries.

The service should allow to:

• Store single log line
• Store batch of log lines
• Print history of stored logs (all, last x)
• Print number of stored logs
• (optional) Simple authentication mechanism to restrict read/write access.
• (optional) Support for log buckets, so logs from different applications can be separated i.e. depending on source or some token used.

Solution notes

• 🔱 clean architecture (handler->service->repository)
• 📖 standard Go project layout (well, more or less 😊)
• 🔄 gRPC + gateway for REST API
• 🐳 dockerized + docker-composed
• 🐘 ImmuDB in a standard SQL mode used (easy to replace with any other SQL DB)

HOWTO

• Run in docker-compose with make dc. This will start logapi and immudb containers, create users and loglines tables and a test user test with password test.
• Run Postman collection from ./postman to test the API.

TODO

• unit tests
• testing tool
