Data & Analytics

flaminis Skill

Ingest tabular Parquet files into Dalaran chunk streams with dalaran.experimental.ParquetReader. Read when converting trajectory or sensor tables (LeRobot-style parquet, exported logs) into entities and components — column grouping, timeline/index columns, static columns, and lenses (DeriveLens) that assemble the typed components (Transform3D, Scalars) from the reader's grouped struct/scalar output. Builds on dalaran-chunk-processing and dalaran-data-model.

flaminis Skill

Core mechanics of the Dalaran Chunk Processing API (dalaran.experimental) — LazyChunkStream pipelines, Chunk, lenses (MutateLens/DeriveLens/Selector), RrdReader, writing optimized RRDs. Read BEFORE writing any ingestion/conversion/preprocessing code (convert an MCAP, build a recording from a dataset, preprocess an .dlr, port an old converter): it mandates reader+lens pipelines and steers away from hand-built chunks — no Chunk.from_columns for data a reader/lens can produce, no per-message rr.log, no manual pa.array assembly. Source-specific knowledge lives in the importer skills (dalaran-mcap, dalaran-urdf, dalaran-parquet, dalaran-lerobot); read dalaran-data-model first to decide what the data should become.
