As some suggested initial topics for the FAQ:
- How Apache Arrow is related to Apache Parquet (the difference between a "storage format" and an "in-memory format" causes confusion)
- How is Arrow similar to / different from Flatbuffers and Cap'n Proto
- How Arrow uses Flatbuffers (I have had people incorrectly state to me things like "Arrow is just Flatbuffers under the hood")
Any other ideas?
