Apache Avro is a data serialization system providing rich data structures, a compact binary format, container files, and RPC support, with schemas defined in JSON and stored alongside the data. It has mature implementations across many languages including Java/JVM, Python, C/C++/C#, PHP, Ruby, Rust, JavaScript, and Perl.

Use cases

• serialize structured records to a compact binary format
• store self-describing data files with embedded schemas
• evolve data schemas over time without breaking readers
• exchange data between services in streaming pipelines
• implement RPC with schema negotiation
• generate typed code from schemas in statically typed languages
• read and write Avro files for Kafka and Hadoop ecosystems

When to choose

• you need schema evolution and self-describing binary data
• you are building streaming data pipelines (e.g., Kafka) or big data workflows
• you need consistent serialization across many programming languages
• you want dynamic-language-friendly serialization without mandatory code generation

When to avoid

• you need human-readable data interchange (use JSON instead)
• you want a strongly-typed IDL-first workflow with gRPC-style services (consider Protocol Buffers or Thrift)
• your payloads are tiny and text-based simplicity matters more than compactness
