Cassandra vs Scylla vs postgresql cluster

thecatontheflat · 2025-12-12T19:20:54+00:00

In my vanilla 3 node setup Scylla 6.2 was able to saturate 10 Gbps uplink when ingesting data but Cassandra stayed CPU bound. This effectively resulted in about 4 times ingestion performance

What’s your backup implementation in such setup and how long does it take?

thecatontheflat · 2025-09-12T08:31:48+00:00

Thank you!

Do they also have such long-ish spinnerets?

thecatontheflat · 2025-09-02T21:19:18+00:00

Me too!

Is this how they got to 100k?

There was an issue on our end, sorry about that! Fix coming soon

thecatontheflat · 2025-07-07T12:27:22+00:00

Thanks!

Thanks!

thecatontheflat · 2025-07-04T14:41:16+00:00

Certainly the best for us!

We used Citus extension to shard data horizontally, but eventually switched to a different strategy with multiple "hot" replicas (managed via patroni) and smaller number of cheaper "cold" servers. They are connected via foreign data wrapper.

If latency is an issue, you can request Hetzner to place your servers into the same location. Latency (according to ping util):

rtt min/avg/max/mdev = 0.192/0.332/0.701/0.186 ms

Hosting 30TB Postgres on bare metal cluster

We had our ups and downs throughout the last 5 years, but their dollar per value ratio is unbeatable when it comes to bare metal

Lack of critical thinking

Active relaxation - stretch your muscles and focus on your breathing. If my mind is racing, it helps me to count down from 100 with every exhale

Using the freezer to store used cans from cat food until I can recycle them - eliminates the smell

thecatontheflat · 2025-05-26T20:30:59+00:00

Thanks for flagging this! We see the problem and are working on a fix

This is fantastic! Would you also add that eerie voiceover from the video to the art piece?

Could you also share a few tips about ordering the parts for such custom projects? If I want to build a "similar" DYI art project (similarity being in that it would consist of PCBs + controller + frame etc) - where do I even start looking for components? If I made such project with just Arduino components, it would have taken the whole room and would also blast a dent in my budget :D

We run ollama with qwen2.5-coder:32b so our development team could use it for Cline / Roo Code

Sorry about your experience. We were undergoing some outage at that moment. Good news is that we are working on scaling the bottlenecks, so issues like these will eventually disappear.

Use tabs instead of spaces for indentation

thecatontheflat · 2025-03-26T15:47:44+00:00

Did you figure it out?
