## Useful for

- Read a Parquet file into an Arrow table and process it in Python or C++
- Transfer a dataframe between Java and C++ processes via Arrow IPC without serialization
- Stand up an Arrow Flight RPC service to exchange data between distributed components

## Why it’s here

- Star-counter measurements on 2026-10-29 (UTC), 00:09–03:00: 17244 → 17244 stars (+0). This is the change over that interval.
- Estimated end-of-day forecast: about +4 stars, using observed gains and the previous day.
- About 8 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 4,415
- Issues and pull requests: 51,050
- Watchers: 343
- Average over the last week: 5 per day
- Usual pace: 3 per day
- Stars in the last hour (measured): 0
- Latest release: apache-arrow-26.0.0 (2026-10-09)

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
