Hi Marina, Thanks for reaching out. Hudi is now part of the Apache Software Foundation actually. :)
Cutting to the chase, although you can build real-time dashboards using both, both systems are pretty different and provide different tradeoffs. For e.g: - AresDB primarily keeps data in memory (so queries could be faster, but data size could be limited) - While Hudi works with a shared storage model writing data out persistentlyto S3/HDFS etc, so you can scale to very large datasets - Query performance on Hudi is left upto to the engine you choose. (you could cache data infront of S3/HDFS, but again could still be slower than in-memory) Hope that helps Thanks, Vinoth On Sun, Nov 24, 2019 at 8:58 AM Marina <ppi...@yahoo.com.invalid> wrote: > Hi, I was reading Uber engineering blogs about your Big Data backend > architecture - very interesting problems you guys are solving and very > interesting architecture approaches.I noticed that there are two > open-source systems created/maintained by Uber - Hudi and AresDB > (Introducing AresDB: Uber's GPU-Powered Open Source, Real-time Analytics > Engine > > | > | > | > | > | > | > > | > > | > | > | > | > Introducing AresDB: Uber's GPU-Powered Open Source, Real-time Analytics ... > > AresDB, Uber's open source real-time analytics engine, leverages GPUs to > enable real-time computation and data p... > | > > | > > | > > > > ).I'm a bit confused as to what are the differences/goals/needs for both > systems... > Both seem to be addressing the issue of ingesting/storing large quantities > of data and providing real-time (and other types) access to query the > data.... > Thank you!Marina > >
