Introduction

This is my pet-project directed to learn such technologies, as:

• Protocol Buffers
• Some parts of Spring (BeanPostProcessor, AOP, etc.)
• NoSQL (Redis, Neo4j)
• Spring Cloud
• Tests (testcontainers)

What and when to use

• Protocol Buffers fox advanced serialization/deserialization speed, solve problem with Java native mechanism
• Redis, as says Chat GPT, for caching (I think in sessions, but not sure) (update 2: Chat GPT suggest to use it in real-time notification system)
• Neo4j for recommendation system
• Spring Cloud just for fun, it's my 4 time to use it
• DestructionAwareBeanPostProcessor
• Java RMI to remote administration
• gRPC to communicate between two microservices

Idk

• I want an achievement system

TODO

• JWT-tokens
• Email verification
• Business-valued email sending on registration
• Maybe store all user's ip addresses to notify if it sing in from strange device
• send suspect notification to account owner on throwing exception during sign-in
• Store known user hosts in Auth module and send notification on suspect log in datatypes for network
• Move to scalable id generation
