Thanks for sharing, Slim! I had a look at the report (except for two pages which were not available in the preview). It compares four different tasks on a setup with 4 rather small nodes (8 cores, 16GB memory). I could not find which versions of Flink and Spark were compared.
The comparison tasks are: 1) WordCount for "batch processing" 2) KMeans for "Machine-learning" 3) PageRank for "Graph-processing" 4) Some kind of relational query (details probably in the two missing pages) Flink outperforms Spark in all tasks except WordCount. The results should not be taken too serious due to the small number of nodes and low number of different tasks (only one task characterizes a task category). K-Means and Wordcount are certainly not representative for the very diverse categories machine-learning and "batch processing". Same applies for relational processing which could be a single table aggregation or a cascade of a dozen joins. The results are very motivating though :-) I hope to see more independent benchmarks in the future. 2015-07-05 19:02 GMT+02:00 Stephan Ewen <se...@apache.org>: > Hi Slim! > > Thank you for the link. > > Unfortunately, I cannot access the contents.
