Which one should I pick for a new project?

That depends entirely on what your project needs to do—these are two fundamentally different libraries solving different problems.

lmax-exchange/disruptor is a high-performance inter-thread messaging library. Pick it if you need:

• Ultra-low-latency communication between threads
• A lock-free ring buffer for event passing
• High throughput with minimal garbage collection
• Use cases like financial trading systems, real-time data processing, or event-driven architectures

The RepoPilot verdict flags it as "GO — Healthy across all four use cases," indicating it's production-ready and well-maintained.

mybatis/mybatis-3 is a SQL mapping framework for Java. Pick it if you need:

• Object-relational mapping (ORM) for database access
• Dynamic SQL generation
• Annotation-based or XML-based query definitions
• A lightweight alternative to full ORMs like Hibernate

In short: Choose disruptor for high-performance thread communication; choose mybatis-3 for database persistence. They're not competitors—you could use both in the same project (disruptor for internal messaging, MyBatis for database access).

What's your project's primary use case?

FOLLOW_UPS:

• Does your project involve high-frequency inter-thread messaging?
• Do you need to interact with a relational database?
• Are you building a financial or real-time trading system?
