Parquet
Parquet graph-directory helpers from annnet.io.parquet.
The public functions are to_parquet(...) and from_parquet(...). The Parquet
reader and writer remain format-specific, but intermediate
annotation tables are built through AnnNet's centralized dataframe backend
helpers instead of choosing Polars or pandas locally.
annnet.io.parquet
Parquet import/export helpers for AnnNet.
Provides: to_parquet(G, path, ...) -> None from_parquet(path, ...) -> AnnNet
This module stores AnnNet graph tables and metadata as Parquet-backed files. Dataframe construction and Parquet IO are routed through AnnNet's dataframe backend via the IO common façade.
