Developing Tenzir
Tenzir-specific idioms, APIs, and abstractions for C++ development.
Core Principle
Work on columns, not rows. Tenzir uses Apache Arrow for columnar data processing. Evaluate expressions once per series or slice, then iterate if row-wise access is needed.
Topics
APIs and Patterns:
- data-access.md — Reading and iterating columnar data
- data-building.md — Constructing series and table slices
- variant-access.md — Working with variants and match
- error-handling.md — TRY, check, and expected patterns
- functions.md — Implementing TQL functions
- operators.md — Implementing TQL operators (incl. secrets)
Tooling and Conventions:
- external-files.md — Third-party code scaffold
- utilities.md — Generic utilities in tenzir::detail
- hashing.md — Hashing infrastructure
- parser-combinators.md — Parser combinator framework
- common-types.md — Reusable common types
