We Just Cut 85% of Our Data Streaming Pipelines Cost! – Yigal Pinhasi, ML & Data Engineer Tech Lead @ AppsFlyer

Moving from 30 to 150 Billion daily events can be regraded as a huge success, but at some point you come to the conclusion that the streaming model that served you up until now is creating too many pains, and is no longer suitable!

Join Yigal on his streaming journey that began with some difficult takeaways from AppsFlyer’s previous streaming model, and ended with rebuilding a new streaming model on production that now solves most of our issues, while cutting 85% of our streaming costs along the way.

Develop Spark pipelines using production data without risk – Jonathan Rosenberg, Software Developer @ Treeverse

In order to deliver high-quality data products, pipelines must be rigorously tested before they are deployed into production. Today, testing on production data requires either using a subset of the data or creating multiple copies of the data. The use of sample data is not sufficient for testing. It is essential to have a testing environment where you can test your end-to-end data pipeline against production data. Using lakeFS, you can test the pipeline on the entire production data set with zero copying, and without risk.
