The Learni story
Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Why this program matters
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Program
Module 1Delta Lake Fundamentals: Installation and First Concepts (Spark, Delta CLI)
Discover the essential principles of Delta Lake to transform your data lakes into reliable solutions, install the Spark environment with Delta Lake using precise commands, create your first Delta table from raw data, explore the optimized Parquet format and transactional metadata, perform practical exercises on real enterprise datasets, produce a simple deliverable like an initialization report to validate your skills from the first day.
Module 2Basic Delta Lake Operations: ACID Read and Write (Spark SQL API, Merge Modes)
Dive into CRUD operations with Delta Lake, perform secure transactional reads and writes using Spark SQL and DataFrames, test write modes like append and overwrite on real customer data cases, integrate merge for incremental updates without duplication, practice on enterprise scenarios like daily log ingestion, generate validation reports, and optimize your first pipelines for immediate reliability.
Module 3Delta Lake ACID Transactions: Consistency Guarantees (Isolation, Atomicity, Durability)
Master the ACID transactions that set Delta Lake apart from traditional data lakes, simulate concurrent failures to observe resilience in real time with Spark, configure checkpoints to speed up consistency checks, apply constraints like checks and nullability on business tables, work on collaborative exercises mimicking enterprise data teams, produce a transaction audit as a concrete deliverable to demonstrate the robustness of your skills.
Module 4Delta Lake Time Travel: Versioning and Schema Evolution (VACUUM, HISTORY)
Explore time travel to navigate data history effortlessly, use HISTORY and TIME TRAVEL commands to restore past versions on modified datasets, manage schema evolution with mergeSchema for evolving pipelines, safely clean old files with VACUUM, apply these techniques to a red thread financial analysis project, create a versioning report as a valuable deliverable to boost your professional expertise.
Module 5Delta Lake Optimization: Performance and Integrations (Z-Order, Bloom Filters, Pipelines)
Optimize your Delta tables for ultra-fast queries by implementing Z-Order indexing and Bloom filters on massive volumes, analyze performance metrics with DESCRIBE HISTORY and EXPLAIN, integrate Delta Lake with tools like Databricks or AWS Glue for enterprise deployments, build a complete end-to-end pipeline on your red thread project, evaluate speed and cost gains, finalize with a personalized optimization plan as a certifying deliverable for your new skills.

Our method
Training quality, guaranteed at every step
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.
You meet the trainer beforehand
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
- Live briefing on goals and team context.
- Veto right — we swap the trainer for free if needed.
Content tailored to your context
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
- Hands-on cases drawn from your stack and projects.
- Program co-written then validated by your team.
Continuous quality follow-up
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
- NPS, knowledge quizzes and skills self-assessment.
- Satisfaction guarantee: fully satisfied or free rework.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
