TECHNOLOGY PROFILE · TECH-0008
Apache Arrow
Columnar in-memory data format and interoperability libraries.
Reference link only — not reviewed this edition. This profile preserves the prepared catalog’s original descriptions. Advantages depend on the workload; comparisons are editorial, not benchmark results.
Where it has an edge
Compatible columnar layouts reduce serialization and copying between tools compared with row-wise object exchange.
Best-fit problems
Sharing large tabular batches across languages and systems.
Tradeoffs & cautions
Zero-copy is conditional on layout and API compatibility; it is not a database.
What to test before choosing
Measure wall time, peak memory and IO on a representative dataset; verify numerical and schema equivalence.
Runtime & hardware
Local CPU; GPU where stated
Access & licensing
Open-source core; verify component licenses
Execution
Local / self-hosted
Lifecycle
Not independently audited
Comparison basis
Editorial problem-fit judgement; no head-to-head benchmark performed
