Open-sourcing Polynote: an IDE-inspired polyglot notebook
We are pleased to announce the open-source launch of Polynote: a new, polyglot notebook with first-class Scala support, Apache Spark integration, multi-language interoperability including Scala, Python, and SQL, as-you-type autocomplete, and more. Polynote provides data scientists and machine learning researchers with a notebook environment that allows them the freedom to seamlessly integrate our
Java's new Z Garbage Collector (ZGC) is very exciting
Java 11 has recently been feature frozen and contains some really great features, one in particular we’d like to highlight. The release contains a brand new Garbage Collector, ZGC, which is being developed by Oracle that promises very low pause times on multi-terabyte heaps. In this article we’ll cover the motivation for a new GC, a technical overview and some of the really exciting possibilities
JVM Profiler: An Open Source Tool for Tracing Distributed JVM Applications at Scale
JVM Profiler: An Open Source Tool for Tracing Distributed JVM Applications at Scale Computing frameworks like Apache Spark have been widely adopted to build large-scale data applications. For Uber, data is at the heart of strategic decision-making and product development. To help us better leverage this data, we manage massive deployments of Spark across our global engineering offices. While Spark
Neanderthal - Fast Native Matrix and Linear Algebra in Clojure
Very Fast On the GPU: almost 3000x faster for large matrices than optimized Clojure/Java libraries! On the CPU: 100x faster than optimized pure Java. Works on AMD, Nvidia, and Intel hardware! Optimized for Clojure Built with Clojure in mind, and implemented in Clojure. Sane interface and functions that fit into functional style while still respecting the reality of number crunching. Comes with fas
Java in Flames
Java mixed-mode flame graphs provide a complete visualization of CPU usage and have just been made possible by a new JDK option: -XX:+PreserveFramePointer. We’ve been developing these at Netflix for everyday Java performance analysis as they can identify all CPU consumers and issues, including those that are hidden from other profilers. ExampleThis shows CPU consumption by a Java process, both use

Etsy Engineering | Introducing statsd-jvm-profiler: A JVM Profiler for Hadoop
At Etsy we run thousands of Hadoop jobs over hundreds of terabytes of data every day. When operating at this scale optimizing jobs is vital: we need to make sure that users get the results they need quickly, while also ensuring we use our cluster’s resources efficiently. Actually doing that optimizing is the hard part, however. To make accurate decisions you need measurements, and so we have cr
Factual | Profiling Hadoop Jobs With Riemann
Factual processes nontrivial amounts of data. Our analyses may range over 1011 records, reading hundreds of gigabytes to hundreds of terabytes of source data and intermediate representations. At this scale, performance optimizations can save us significant time and money. We use VisualVM, jhat, and Yourkit for memory and CPU profiling, and the excellent Criterium for microbenchmarks in Clojure. Th
