Explore how to integrate TigerBeetle, a high-performance distributed financial accounting database, with Elixir applications through this conference talk from ElixirConf EU 2025. Discover TigerBeetle's impressive capability to process financial transactions up to 1000x faster than general-purpose databases while maintaining mission-critical safety standards. Learn about TigerBeetle's specialized data model and examine TigerBeetlex, an Elixir client library built on top of TigerBeetle's official Zig client. Dive deep into the library's API and internal architecture, gaining insights into binary implementation within the BEAM VM, understanding NIF resources, and seeing how TigerBeetle's non-blocking API seamlessly integrates with Elixir's message-passing paradigm. Examine critical design decisions including the tradeoffs between macros versus code generation and efficient mutability versus familiar immutability, understanding why these choices are essential for creating idiomatic Elixir libraries that deliver both performance and developer experience.
