Evaluating MLOps Tools Watch this talk on YouTube Hamel Husain Stanford CS329S ML Systems Design, February 2022
This document summarizes a benchmark study of file formats for Hadoop, including Avro, JSON, ORC, and Parquet. It found that ORC with zlib compression generally performed best for full table scans. However, Avro with Snappy compression worked better for datasets with many shared strings. The document recommends experimenting with the benchmarks, as performance can vary based on data characteristic
2. Honestly... • I know a lot more about Apache Storm than I do Apache Spark Streaming. • I've been involved with Apache Storm, in one way or another, since it was open-sourced. • I'm admittedly biased. 3. But... • A number of articles/papers comparing Apache Storm and Spark Streaming are inaccurate in terms of Storm’s features and performance characteristics. • Code and configuration for those stu
This document discusses various big data frameworks including Spark, Scoobi, Hadoop, and GraphX. It provides an example of using Spark to interactively analyze log data stored on HDFS. Spark allows loading data into memory and running multiple queries efficiently. The document also discusses benefits of Spark such as its scalability, libraries for SQL, streaming, machine learning and more.Read les

That was a pretty good time. Saw lots of good and wicked smaht people, and I got a lot of great questions after my talk. The slides are up on slideshare, and here are the PDF slides. UPDATE: Gil Raphaelli has posted his python bindings he wrote for our libyahoo2 use in our Ops IM Bot. There was something that I left out of my slides, mostly because I didn’t want to distract from the main topic, wh
