Prism

A simple, fast, and distributed data broker for clustered server use.

Purpose

The typical problem with distributed servers is encountering the three main issues:

• The server typically has to rely on a central DB server (which adds latency to farther regions)
• A server that does use distributed DBs needs to handle synchronization between the DBs (which is hard to do correctly)
• Database mutations and queries are typically slow and asynchronous operations are difficult to implement correctly

Thus, the solution is to use a broker to extract all the database logic. However, we want a distributed broker so that we are able to limit latency but also have some way to handle synchronization between the brokers.

Architecture

Features/Development

• Net.Server - central server to handle all UDP traffic
• Net.Manager - central manager to handle all connections
• Net.Conn - connection struct to store connection info
• Net.Packet - Protobuf packets to handle all the different packet types
• Net.Cluster - functions to connect to other nodes and broadcast updates (via OTP)
• Net.Reliablity - enforces reliability on all packets as well as handling retries
• Net.Security - utilizes AES to encrypt and decrypt incoming packets
• Net.Dispatch - performs/stores all packet handlers (based on an ID specified)

Current Status

• Basic UDP server
• Basic packet handling
• Basic cluster connection
• Finish packet layer
• Add service authentication
• Implemented security via AES encryption
• Add database connection
• Add redis connection
• Add proper regional handling
• Find a way to combat synchronization issues (few will arise because of Cluster implementation)
• Add better logging
