Our paper "LightSaber: Efficient Window Aggregation on Multi-core Processors" was accepted in SIGMOD'20! Check out the code of #LightSaber (github.com/lsds/LightSaber)! Kudos to Alexandros Koliousis Peter Pietzuch and Holger Pirk. Imperial Computing LSDS Research Group

TIL that k8s memory limits are bad for processes which use mmap() - the memory.usage_in_bytes includes all pages, not just anonymous pages. Been open for a few years now github.com/kubernetes/kub… Deja vu, back to YARN-1775

If you liked our #SIGMOD2020 tutorial on the evolution of stream processing systems, our extended (30+ pages) survey on the topic is now online: arxiv.org/abs/2008.00842 Feedback and comments welcome!

Unless you care about latency.

Excited to be giving a talk Community Over Code this Tuesday about the Hive runtime filtering enhancements I have been working on for the past few months with some neat perf results! Join to learn more: apachecon.com/acah2020/track… #ACAH2020 #OpenSource #BigData #ApacheHive #ApacheOrc

An online presentation about runtime filtering enhancements in Apache Hive tomorrow at 20:15 GMT+2 Community Over Code along with Panagiotis Garefalakis . Pass by to say hi and possibly learn something new 😄 apachecon.com/acah2020/track…

You are in a job interview. The interviewer says "Do you understand Kerberos?". What do you say?

On January 20, the Apache Calcite community is organizing a virtual meetup (meetup.com/Apache-Calcite…); if you are interested in data management & data integration check the agenda and join the event :)

nice to see Apache Hive getting a product placement here

Fancy a physical (!) trip to London to discuss your work and network with the British database community this December at Imperial College London? Consider submitting a paper to BICOD2021: bicod.uk/cfp. Despite the name, we invite contributions from anywhere.

This week’s podcast is framed as a Flink vs Kafka Streams vs ksqlDB debate, but if you ask me the winner is anyone who learns some new stream-processing techniques. 😀 Comparing Stream Processing Tools youtu.be/Wqko7MunKZs with Matthias J. Sax 🦦 and Jeff Bean.

FLIP-291 brings the Adaptive Scheduler one step closer to becoming the new default for streaming and marks an essential milestone in building the state-of-the-art AutoScaler for Apache Flink 🐿️🤓 Read more in a 🧵👇

🐿 The open preview of Apache Flink on Confluent Cloud is now available! Now, you can easily build high-quality, reusable data streams with the industry's only cloud-native, serverless Flink service. Check out our blog to see how it works ➡️ cnfl.io/463JEfF | #Current23

Here we go, ready to disrupt the industry. The most exciting product I’ve ever worked on is entering the Open Preview! 😍 #Current23

On Tues Nov 7, we have TWO meetups happening. First up, a social mixer hosted by Onehouse and Confluent for folks attending #flinkForward. meetup.com/seattle-data-e…

Let me know if you are attending #FlinkForward and want to chat more about Apache Flink and how we are dealing with streaming failures at Confluent !

Please retweet! Searching for a PhD student for my VIDI grant. The team is building a programming model & self-driving streaming dataflow engine for Transactional Stateful Functions. Apply here by 10th February (and drop me an email): tudelft.nl/over-tu-delft/…

A year ago, Immerok 🐿️s joined Confluent, and the team has already shipped an open preview of Apache Flink serverless offering. 😍 Join our stream processing workshop in less than a week to see what we've built so far. 🤓🏗️ events.confluent.io/ws-stream-proc…
