Big Data Week

09/06/2026

Now onto our second session at Bucharest Big Data meetup: Roberto Comsa, Data Engineer at esolutions.tech is unpacking why data validation matters in CDC streaming pipelines.

Through a practical production journey spanning CDC sources, NiFi, Kafka, Spark, and Delta Lake on MinIO, Roberto is showing how powerful real-time data products can be, but also how subtle drift and unnoticed issues can quietly impact data quality, reliability, and trust.

A strong takeaway from the session: even when heavy validation at the source isn’t possible, lightweight checks and stronger end-to-end ownership can go a long way in catching issues early and building more resilient streaming platforms.

We’re live at Bucharest Big Data meetup and the first talk of the evening is underway: Catalin Duta and Anamaria Lauric from ING Hubs Romania are taking us through the journey from on-premise to cloud with real-time data.

One key takeaway so far: as more organizations work across both on-prem and cloud environments, real-time and near-real-time data flows are becoming essential for keeping systems aligned and supporting analytics and operations without delay.

Great insights on how streaming and modern data platforms enable seamless, low-latency access to data across environments and help build more connected, scalable, and future-ready ecosystems.

Why does data validation matter so much in CDC streaming pipelines? Roberto Comsa, Data Engineer at eSolutions.tech, will explore this scenario through real production systems.

Working with NiFi, Kafka, Spark, Delta Lake, and MinIO, he’ll walk through how CDC data flows from ingestion to consumption and how small issues in streaming pipelines can quietly impact data quality over time. The focus will be on practical validation strategies, early detection of drift, and building trust in continuously moving data.

How do you enable real-time data flows across on-prem and cloud systems, without breaking consistency or scalability?

During their session, Catalin Duta (DevOps Engineer) and Anamaria Lauric (Chapter Lead Engineer) from ING Hubs Romania will explore exactly that. They’ll share how modern streaming platforms help bridge hybrid environments, enabling continuous data movement and supporting both operational and analytical use cases.

Expect practical insights on:
• building real-time and near-real-time data pipelines
• working across on-prem and cloud systems
• designing scalable, streaming-first architectures
