About

Cloudsqale is a blog about optimizing interactive ad-hoc and batch workload for large scale analytics in Amazon AWS cloud.

My name is Dmitry Tolpeko, and my professional interest is performance of distributed computing systems for heavy analytical workloads using Apache Spark, Delta, Databricks and Amazon EMR.

Using highly automated approaches, I specialize in optimizing queries, but much more importantly in optimizing the entire data platform running thousands of ad-hoc and ETL queries and jobs daily in multi-cluster and multi-vendor environments, discovering and resolving performance and cost issues and bottlenecks at scale.

Currently I live in Barcelona, Spain. You can reach me at dmtolpeko@gmail.com.
