What is nanoparquet?

nanoparquet is chasing byte-level agreement with the Java and Rust Parquet readers, not feature count.

nanoparquet reads and writes Parquet from R with no Arrow dependency, which is its entire reason to exist. The 0.4.0 line renamed the reader API and added schema authoring plus `append_parquet()`, and the 0.5.x releases have gone after interoperability: definition and repetition level encodings the Apache Parquet Java library expects, flatbuffer alignment the Rust arrow-rs reader expects, 128-bit decimals, and Polars-written files that omit the dictionary page offset. The newest release adds `bit64::integer64` columns and writing to stdout.

What is pharmaverseadam?

pharmaverseadam is the pharmaverse's test-data mirror, and it now covers neurology.

pharmaverseadam ships pre-built ADaM datasets generated by running the admiral family's own templates, so package authors and trainers have realistic analysis data without writing derivations first. The 1.3.0 release pulls in `ADAPET`, `ADTPET` and `ADNV` from admiralneuro and an anti-drug antibody dataset from admiral itself, and regenerates everything against current versions of seven upstream packages. Variables are now ordered and grouped to ADaM IG structure.

nanoparquet is chasing byte-level agreement with the Java and Rust Parquet readers, not feature count.

◆ Current state

nanoparquet reads and writes Parquet from R with no Arrow dependency, which is its entire reason to exist. The 0.4.0 line renamed the reader API and added schema authoring plus `append_parquet()`, and the 0.5.x releases have gone after interoperability: definition and repetition level encodings the Apache Parquet Java library expects, flatbuffer alignment the Rust arrow-rs reader expects, 128-bit decimals, and Polars-written files that omit the dictionary page offset. The newest release adds `bit64::integer64` columns and writing to stdout.

◆ Where it's heading

Almost every entry since 0.4.0 names another engine — Java, arrow-rs, Polars, Arrow schema metadata — which tells you the maintainers are treating cross-reader fidelity as the product rather than R-side ergonomics. The type system is filling in from the edges: DECIMAL beyond 8 bytes, UUID, FLOAT16 and INTERVAL as raw lists, and now 64-bit integers with an explicit read-type option instead of a silent cast to double. Writing to `:stdout:` points at a second audience, shell pipelines rather than interactive R.

◆ Prediction

The remaining unmapped Parquet types the changelog has been parking in raw-vector lists — FLOAT16 and INTERVAL — are the obvious next targets, following the same pattern by which DECIMAL and UUID graduated to real R types.

P0.0

pharmaverseadam is the pharmaverse's test-data mirror, and it now covers neurology.

◆ Current state

pharmaverseadam ships pre-built ADaM datasets generated by running the admiral family's own templates, so package authors and trainers have realistic analysis data without writing derivations first. The 1.3.0 release pulls in `ADAPET`, `ADTPET` and `ADNV` from admiralneuro and an anti-drug antibody dataset from admiral itself, and regenerates everything against current versions of seven upstream packages. Variables are now ordered and grouped to ADaM IG structure.

◆ Where it's heading

Coverage tracks the pharmaverse's own therapeutic-area expansion with a lag of one release: pediatrics arrived in 1.1.0, metabolic in 1.2.0, neurology in 1.3.0. The other consistent thread is a slow move off development versions — 1.1.0 and 1.2.0 both had to pin unreleased upstream builds to get working templates, while 1.3.0 cites released versions throughout. Reorganising the reference page by therapeutic area is the same maturation showing up in documentation.

◆ Prediction

Expect the next release to follow the established pattern — a refresh against current upstream versions plus datasets from whichever admiral therapeutic-area package reaches a stable release next.
