Which techniques do you use to increase your trust in model generated code? Submitting the same task to multiple models can produce interesting results.

Secure & Low-Latency Queries at scale with Raft Data Platform - [R]DP - Raft | Operationalize Data & Agentic AI Raft is a DefenseTech Product company on a mission to connect humans with data at the edge. One of our products is the Raft Data Platform -[R]DP. Weโ€™ve built the [R]DP and operationalized it in severa...

For this demo I generated a 100TB data set (50GB/min) and maintained sub-second query latencies

Perfect Polish smile. Just need a black and white copy for your passport.

With @apachepinot.bsky.social I can query a 100TB data set and using itโ€™s Star-tree index can get 20ms query latency!

Has anyone used DuckDB for TB or PB scale data sets? Asking for a friend.

I was reading this book recently and stumbled across this handy formula for calculating Kafka partitions:

Max(target tp / producer tp, target tp / consumer tp)

@startreedata.bsky.social Thank you and Merry Christmas! My community box arrived last night and with my winnings from the MI competition I recently purchased a pair of skis. #startree

Iโ€™m planning to use ST to generate 100TB of data

What is the graph trying to show? Do you have any examples of virtual threads from prod?

Last night, I was exploring thread safety issues with ChatGPT. It only took two attempts to generate a test that exposed the lack of a synchronized block for a section that updates multiple member variables. #java

Assuming refs could handle the new rule it would prevent goals from offside situations, but it would hurt counter attacking.

Itโ€™s been a while since weโ€™ve had this discussion. Could you remind me when you would call offsides?

Correct! Thanks for playing! This was based on an example from โ€œJava Concurrency in Practiceโ€.

@thegeeknarrator.bsky.social thanks for the book recommendation. This one is much easier to read

Great point! Perhaps โ€œperformance over precisionโ€ is a more appropriate phrase for this trade off.

Another example that comes to mind is from Kafka Streams where you define the grace period for windows with late arriving events.

In which cases is performance more important than correctness?

Approximations. Like Pinotโ€™s DISTINCTCOUNTHLL which returns an approximate distinct count using HyperLogLog.

Does anyone else have a good example?

And your data model can be only as good as the query patterns it was designed to support

04.11.2024 21:53 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 1    ๐Ÿ“Œ 0

Both if possible. But if not, then correctness over performance. And all other key benefits of the Responsive platform itself (above and beyond Kafka Streams)

03.11.2024 22:45 โ€” ๐Ÿ‘ 1    ๐Ÿ” 0    ๐Ÿ’ฌ 0    ๐Ÿ“Œ 0

How does Responsive support calls to external services while processing the stream?

What are the current and future benefits of using SlateDB?
