I think Rust's slow builds are still killing adoption, but there is hope. I have just read Rust compiler performance survey 2025. Build performance averaging 6/10 satisfaction with 55% waiting 10+ seconds for rebuilds proves this is still Rust's #1 problem. What frustrates me is…

VictoriaLogs gained support for useful features during the last two weeks: 1. Pattern matching - allows searching for logs that match the given patterns (it is easier to use and is much faster than regexp matching). 2. Ability to calculate running stats and total stats, such as…

"S3 is cheaper than EBS". This is the top reason why people want using S3 as a persistent storage for databases such as VictoriaMetrics and VictoriaLogs. They are correct - S3 costs $23/TB/month, while EBS gp3 costs $80/TB/month (but there is st1 at $45/TB/month and sc1 at…

Every read from S3 takes 100ms-200ms on average. So reading a single byte takes roughly the same time as reading 10MB of data from S3 at 100MB/s speed. This complicates designing high-performance databases with S3 storage. If the query needs reading a million of 1KB data blocks…

Scaling the pod vertically without restarting is now feasible from Kubernetes v1.33. Normally, if you wanted to give an app (a Pod in Kubernetes) more memory or CPU, you had to restart it. That works fine if the app doesn’t care about restarts, but some apps really don’t like…
