@gwenshap I loved most of the papers from 15721.courses.cs.cmu.edu/spring2023/sch…
@abacaj What are you using for your agent?
@richardartoul Do you know what P99 looks like?
TIL about Apache Ozone. Been thinking about a generalized implementation of Raft to pair with S3 similar to Neon’s Paxos layer. Ozone is the closest I’ve seen. This without the Hadoop cruft would enable more infra to run directly on S3. /ht @_a__w_ ozone.apache.org/docs/1.3.0/con…
Andrej Karpathy is a legendary researcher who helped start OpenAI and created Stanford's first deep learning class. @karpathy's advice on how to learn AI: (1) 10,000 hours of deliberate practice will make you an expert. You can iterate as you work. Only compare yourself to the past, not to others. (2) Don't worry about making mistakes. You build intuitions on what is useful vs. not useful- they are not dead work. (3) Teach to strengthen your understanding and find gaps in knowledge. Similar to "If you can't explain it to a six-year-old, then you don't understand it yourself" - Albert Einstein.
@jaykreps Won't this put Kafka in the critical request path for all business services writing to it? Also, even high latency across the 2PC can cause issues for business services. That's probably one advantage for using CDC to capture your data through a business database.
How to become expert at thing: 1 iteratively take on concrete projects and accomplish them depth wise, learning “on demand” (ie don’t learn bottom up breadth wise) 2 teach/summarize everything you learn in your own words 3 only compare yourself to younger you, never to others
Anyone know if there is some upcoming training with #ApacheFlink?
@sap1ens Excellent write up, thanks for sharing Yaroslava!
Any presentations or blog posts that do a deep dive comparison between Apache Flink and Kafka streams/ksqlDB? So far, here is what I've found: developer.confluent.io/podcast/flink-…
"This commit allows to optimize performance by providing a new optional mode of TLS sendfile(), in which the extra copy is skipped. Removing this copy improves performance significantly, as TLS and TCP sendfile perform the same operations" git.kernel.org/pub/scm/linux/…
@JSchabowsky Thanks, yes, that does make sense. I guess once you go down the route of offering Kafka as a service you'll need to enforce quotas to manage capacity between the different tenants. That can get mess though if a critical service needs more capacity and it's not available.
When using Kafka for event driven architecture and Kafka is a shared service between multiple teams/services, how do you define ownership?
@MacroAlf I’d love to understand better the risks around owning ADRs specifically for emerging markets.
If you build streaming services based on Change Data Capture (CDC), how do you ensure an upstream DB migration doesn't break the downstream consumer logic? Seems like domain events create a more decoupled architecture, what am I missing? debezium.io/blog/2020/02/1…
@gwenshap Does that also mean you would transfer all the data in the partitions to another broker as well?
@gwenshap As far as I could tell (last time I checked) quotas were still not supported in the Admin/Client API, any plans on adding that functionality?
@jaykreps @confluentinc It would great if Confluent went public so I could invest directly :-)
@amendt @AG1L1S @GamerGeekNews Awesome, thanks guys.
Any laptop recommendations for running Ubuntu for dev work? I'm currently using a Macbook and the keyboard still feels awkward and annoying 😐
