Reference

This section separates ETLantic 0.21 shipped behavior from proposed 1.0 interfaces.

Shipped

• Command-Line Interface
• Python API
• Runtime configuration (Profile, optional etlantic.toml, env vars)
• Configuration today (shipped 0.21 profile + project toml)
• Compatibility Matrix
• Portable Compiler Matrix
• Known Limitations
• Diagnostics
• Exceptions
• DTCS 3.0 Transformation Plan / Rich Portable Analytics models through dtcs>=0.13; ETLantic @Transformation.portable authoring (0.11+) and Polars / PySpark graduated Wave 1/2 compilers plus Pandas / SQL baseline relational compilers via Portable Transform Compiler and Testing Plugins

Future design / proposed 1.0

• Configuration (proposed 1.0 surface beyond shipped toml)
• Environment Variables (proposed names beyond shipped)
• 0.17 continuation families (portable-relational-extended/1, portable-temporal-iana/1, portable-nondeterministic/1, portable-window/2) — see the Portable Compiler Matrix

See Documentation Status for the stability vocabulary used throughout the project.
