formats

DE//AGENT currently lists 3 resources under formats: 2 references, 1 tutorial. Everything below is derived from the live registry — counts, capabilities, verification state and security posture come from the curated records, never from marketing copy.

Documented learning objectives across these resources:

• Match each format to its lane — analytics files, event payloads, in-memory interchange — via Choosing file formats — Parquet, Avro, and Arrow's role
• Argue a format choice with the sources' own wording — via Choosing file formats — Parquet, Avro, and Arrow's role
• Explain why most pipelines use more than one format — via Choosing file formats — Parquet, Avro, and Arrow's role

These resources map to stage: Foundations (3). Follow the four-phase roadmap to place this topic inside a progression instead of learning it in isolation.

Every entry, its shape and its trust state — sorted by the registry's composite score. This table is the honest version of a marketing comparison: no sponsored placements, no unverifiable claims.

How scores are computed: source quality score.

Highest composite score first:

1. Choosing file formats — Parquet, Avro, and Arrow's role score 34.15 — intermediate
2. Apache Parquet Format Documentation score 27.7 — difficulty not documented
3. Apache Parquet Documentation & Spec score 26.7 — difficulty not documented

Scores rank provenance, completeness and trust — read how verification works before adopting anything.
