What is MasterMemory?

MasterMemory is a high-performance, source generator based embedded typed readonly in-memory document database designed for .NET and Unity applications. It boasts impressive speed, claiming to be 4700 times faster than SQLite with zero allocation per query, and maintains a small database footprint. The tool automatically generates a typed database structure from schemas, ensuring type-safe queries with full autocompletion support for optimal performance and usability. Key features include memory efficiency through aggressive string interning, fast load speeds due to MessagePack for C# serialization, flexible search capabilities with multiple key, result, and range/closest queries, and custom data validation. It is particularly well-suited for master data management in embedded applications, data analysis, and game development.

Best used for

Ideal for developers who need to manage master data in .NET and Unity applications, optimize database performance with zero allocation queries, and ensure type-safe data access.

FAQs

What are the primary performance benefits of MasterMemory?

MasterMemory is designed for extreme performance, claiming to be 4700 times faster than SQLite. It achieves zero allocation per query and significantly reduces database size compared to traditional databases. This makes it ideal for read-heavy scenarios where speed and memory efficiency are paramount.

How does MasterMemory ensure type safety?

MasterMemory utilizes a source generator that automatically creates a typed database structure from your defined schemas (classes). This process ensures that all queries are type-safe and benefit from full autocompletion support, enhancing both development experience and code reliability.

Can MasterMemory be used with Unity?

Yes, MasterMemory supports Unity, specifically versions 2022.3.12f1 and newer, which are necessary for C# Incremental Source Generator support. It can be installed via NuGetForUnity, and requires some specific setup for Unity's environment, such as enabling the 'init' keyword and configuring MessagePack resolvers for IL2CPP.
