Talk 2: Low-Level CPU Performance Profiling Examples using Apache Spark, Apache Arrow, and Columnar Databases (Tanel Poder (, Founder and Chief Engineer @ Gluent (

• In this session Tanel Poder will demonstrate some low level performance tools like Linux "perf stat" to measure the memory access traffic and CPU efficiency of different workloads, data structures and programming paradigms.

• We will use a columnar database, a few variations of a Spark job and Apache Arrow data structure iteration as examples.

• This session's goals are to emphasize the importance of using suitable data structures for a task (like a columnar structure for scanning) and that modern CPUs and performance tools give you good visibility into the "CPU-friendliness" of your code.


• Tanel Poder is a co-founder of his current startup Gluent that liberates enterprise data, making it useful across all enterprise.

• Despite holding a CEO title, he was an advanced OS & database systems performance geek for over 20 years and is now hoping to bring some of that skill to the Spark/Big Data world too.


Talk 3: Anirudh Ramanathan ( (Software Engineer, Kubernetes @ Google)

Title: Spark on Kubernetes

Abstract: Engineers across several organizations are working on support for Kubernetes as a cluster scheduler backend within Spark. While designing this, we have encountered several challenges in translating Spark to use idiomatic Kubernetes constructs natively. This talk is about our high level design decisions and the current state of our work.


Anirudh Ramanathan is a software engineer on the Kubernetes team at Google. His focus is on running stateful and batch workloads. Previously, he worked on GGC (Google Global Cache) and prior to that, on the infrastructure team at NVIDIA."
