Soumabrata Chakraborty updated BEAM-9440: ----------------------------------------- Description: While doing a performance evaluation of Apache Beam with Spark Runner - I found that even for a simple word count problem on a text file – Beam with Spark runner was slower by a factor of 5 times as compared to Spark for a dataset as small as 14 GB. You will find more details on this evaluation here - [https://github.com/soumabrata-chakraborty/spark-vs-beam/blob/master/README.md] I also came across this analysis called _**Quantitative Impact Evaluation of an Abstraction Layer for Data Stream Processing Systems_ ([https://arxiv.org/pdf/1907.08302.pdf] / [https://ieeexplore.ieee.org/document/8884832]) According to it, the observation was that for most scenarios the slowdown was at least a factor of 3 with the worse case being a factor of 58! While it is understood that an abstraction layer would come with some performance cost - the current performance cost seems to be very high. was: While doing a performance evaluation of Apache Beam with Spark Runner - I found that even for a simple word count problem on a text file – Beam with Spark runner was slower by a factor of 5 times as compared to Spark for a dataset as small as 14 GB.
