@gunnarmorling There are multiple ways to handle reads, each with its own trade-off space. Many of the recent Paxos read optimizations apply to Caspaxos as well. But if a system handles reads as writes to avoid staleness, then yes - those reads inherit the same issues as writes
@gunnarmorling That said, some systems naturally have an organic single writer/reader per labeled register (e.g., a user working with their own data). In those cases, dueling isn’t really a concern for Caspaxos, especially if the system is modeled as a set of independent, rewritable registers
@gunnarmorling In general I’m not a fan of broad generalizations :) but yeah, it’s nice when a system has a weak leader or a mostly single-writer pattern to guarantee liveness
Spent some time digging into the #CASPaxos paper ("Replicated State Machines without logs"), by @rystsov. It's really easy to follow; do I get it right though that two competing writers could block each other from ever moving beyond the prepare phase? arxiv.org/abs/1802.07000
@gunnarmorling So overall, I think weak-leader election should stay modular and not be bound to any specific replication protocol, as long as the protocol can support it
@gunnarmorling And during outages, it can make sense to let SREs override leader election entirely and pin a static leader to reduce variability and stabilize the cluster
Well, always has been.. Grep is essential for coding — AI or not
turns out that the backbone of agentic AI coding is grep
@_0x5d What do you think made the difference today? Was it a new use case, workflow, or something else gave the boost?
@alenkacz Now I’m working hard on something I need as a surfer—and I believe other surfers need it too! 🏄♂️
@alenkacz When you know how to code, have full-stack experience, and have passions outside of programming, the opportunities are endless. I had an idea for an app, and with fewer responsibilities at the time, I decided to take a leap of faith
@alenkacz Just pursuing the dream of becoming a lifestyle entrepreneur! 😊
Surprising how wrestling with JavaScript years ago helped me onboard with modern C++ & Seastar (cooperative concurrency within core-pinned threads) to develop Redpanda, a distributed streaming platform
Now it's paying off again with SwiftUI, which feels a lot like React
Took me 4 months to get proficient in SwiftUI & iPhone development
@justinjaffray You’re inspiring me to experiment and start writing again! I’ve been itching to write a book for a while now 😅
