Simple Binary Encoding (SBE) is a high-performance binary message codec implementing the FIX SBE standard for low-latency applications, with a schema-driven code generator producing codecs in Java, C++, C, C#, Go, and Rust. It is the reference implementation maintained by the Aeron project and pairs efficiently with the Aeron messaging system.

Use cases

• encode and decode binary messages for low-latency trading systems
• generate type-safe codecs from an XML message schema
• serialize market data with minimal overhead and zero-copy
• exchange messages between Java, C++, Go, and Rust services
• build high-throughput messaging on top of Aeron

When to choose

• you need extremely low-latency, low-overhead binary serialization
• you are building financial/trading systems using the FIX SBE standard
• you want codecs generated from a schema in multiple languages
• you use Aeron messaging and need an efficient presentation layer

When to avoid

• you need human-readable formats like JSON or XML
• your messages are small-volume and serialization performance is irrelevant
• you need schema evolution flexibility beyond SBE's extension model
• you want a general-purpose serialization library with broad ecosystem support like Protobuf
