Without Delta Lake, 65% of traditional data lakes suffer data corruptions (Gartner 2023), leading to average losses of 4.2M€ per major incident.
Imagine your Spark pipelines paralyzed by duplicate writes, rigid schemas, and queries 10x slower.
Result: project delays, GDPR fines up to 20M€, loss of client trust.
Our beginner training avoids these pitfalls: secure your data from Day 1, reduce storage costs by 40%, accelerate business insights by producing ACID-ready tables in 35h.
Discover the basics of Delta Lake for reliable data lakes, install the Spark-Delta environment live on your machine, complete practical setup exercises, create your first Delta table with real customer data, test simple ACID transactions, produce a deliverable: operational table ready for use.
Dive into creating and manipulating Delta tables, perform inserts, updates, and deletes via Spark SQL, manage schema evolution on real e-commerce cases, optimize with Z-Order, generate data quality reports, leave with a functional CRUD pipeline.
Master ACID transactions to avoid corruptions, simulate Spark job failures on large datasets, implement checkpoints and automatic optimizations, analyze Delta logs for debugging, build a data recovery exercise, obtain a deliverable: resilient transactional job.
Explore time travel to navigate data history, query past versions via SQL, perform change audits on real logs, clean up with VACUUM and OPTIMIZE, apply to a GDPR compliance case, produce an interactive temporal audit report.
Boost performance with Delta indexing and caching, integrate into Spark Streaming pipelines, test on real-time IoT streams, prepare for ML with feature stores, review via final project, leave with a portfolio: optimized and deployable Delta Lake pipeline.

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.
