Don't let this gap widen
Without Apache Arrow, data pipelines lose 70% in processing speed, generating 50k€ in unnecessary costs per annual project from oversized infrastructure.
Data teams waste 40% of time on slow conversions, causing critical delays in real-time analytics and 25% losses in business opportunities.
In 2026, 82% of big data companies require Arrow to scale, sidelining non-expert profiles and risking career obsolescence.
Every quarter without Arrow skills widens a fatal competitive gap, with data incidents multiplied by 3.
Dive into Apache Arrow's in-memory architecture to accelerate data processing, install PyArrow and configure columnar schemas suited to enterprise use cases, manipulate massive datasets via Arrow IPC for zero-copy exchanges, perform practical exercises on Pandas-to-Arrow conversion with memory optimization, develop a first columnar ETL pipeline on real data, produce benchmarks showing x10 speed gains, and document configurations for immediate production reuse.
Integrate Apache Arrow with Spark and Dask for ultra-performant distributed queries, explore Arrow Flight for low-latency RPC streaming transfers on clusters, optimize workflows with 2026 extensions for GPU and ML, apply to real-world cases like real-time IoT log analysis, test interoperability with Polars and DuckDB through hands-on exercises, deploy a scalable prototype in Docker/Kubernetes containers, measure ROI with precise metrics, and prepare an enterprise adoption plan to certify your expert skills.
The Training Apache Arrow - Optimize high-performance big data pipelines program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
