Where do you draw the line between Python and a faster language?

<!-- SC_OFF -->I love Python for speed of development, readability, and libraries but I sometimes feel guilty when performance becomes a bottleneck. Curious how others decide when it’s time to switch to C++/Rust/Go instead of optimizing Python. Do you usually push Python as far as possible first, or do you switch early when performance matters? <!-- SC_ON --> submitted by /u/Creepy-Valuable-3685 (https://www.reddit.com/user/Creepy-Valuable-3685)

Learned about vendor lock-in the hard way during my internship. does anyone talk about this at school?
https://www.reddit.com/r/programming/comments/1p7mvxw/learned_about_vendor_lockin_the_hard_way_during/

<!-- SC_OFF -->Just finished my internship at a fintech company (think of Robinhood) and learned something they definitely don't teach you in school. So I was on the data platform team and there was this whole drama while I was there. Basically the company went all-in on one of the big cloud vendors for their data stuff a couple years ago. Everything was integrated, their catalog, governance, the whole stack. Then out of nowhere the vendor raised prices like 40% with barely any notice. The engineering managers were losing their minds. The problem? All the company's metadata was trapped in the vendor's proprietary system. Like literally years of data lineage, access policies, everything. They couldn't just switch because migrating would take almost a year of engineering time. So they just had to pay lol. One of the senior engineers told me this happens all the time. He called it "the walled garden trap." Big companies like Databricks, Snowflake, AWS all want you locked into their ecosystem. Once you're in, switching costs are insane. Made me start reading about open source alternatives. Found this article that explains it way better than I can: https://medium.com/datastrato/if-youre-not-all-in-on-databricks-why-metadata-freedom-matters-35cc5b15b24e](https://medium.com/datastrato/if-youre-not-all-in-on-databricks-why-metadata-freedom-matters-35cc5b15b24e (https://medium.com/datastrato/if-youre-not-all-in-on-databricks-why-metadata-freedom-matters-35cc5b15b24e%5D(https://medium.com/datastrato/if-youre-not-all-in-on-databricks-why-metadata-freedom-matters-35cc5b15b24e) There's this Apache project called Gravitino that's basically an open source metadata layer so you're not dependent on one vendor. Kinda interesting from a systems design perspective tbh. Anyway this whole experience made me think: Do companies actually consider vendor lock-in when choosing tech stacks or do they just go with whatever's easiest? For those who've worked at startups vs big tech, is this more of a startup problem? Is open source infra actually viable for most companies or is it too much ops overhead? Anyone else learn stuff like this during internships that completely changed how you think about tech decisions? Feels like we learn algorithms and data structures but nobody talks about the actual business/infrastructure tradeoffs you deal with in industry. <!-- SC_ON --> submitted by /u/Icy-Perception0 (https://www.reddit.com/user/Icy-Perception0)

I built a distributed message streaming platform from scratch that's faster than Kafka
https://www.reddit.com/r/programming/comments/1p7oqbc/i_built_a_distributed_message_streaming_platform/

<!-- SC_OFF -->I've been working on Walrus, a message streaming system (think Kafka-like) written in Rust. The focus was on making the storage layer as fast as possible. Performance highlights: 1.2 million writes/second (no fsync) 5,000 writes/second (fsync) Beats both Kafka and RocksDB in benchmarks (see graphs in README) How it's fast: The storage engine is custom-built instead of using existing libraries. On Linux, it uses io_uring for batched writes. On other platforms, it falls back to regular pread/pwrite syscalls. You can also use memory-mapped files if you prefer. Each topic is split into segments (~1M messages each). When a segment fills up, it automatically rolls over to a new one and distributes leadership to different nodes. This keeps the cluster balanced without manual configuration. Distributed setup: The cluster uses Raft for coordination, but only for metadata (which node owns which segment). The actual message data never goes through Raft, so writes stay fast. If you send a message to the wrong node, it just forwards it to the right one. You can also use the storage engine standalone as a library (walrus-rust on crates.io) if you just need fast local logging. I also wrote a TLA+ spec to verify the distributed parts work correctly (segment rollover, write safety, etc). Code: https://github.com/nubskr/walrus Would love to hear what you think, especially if you've worked on similar systems! <!-- SC_ON --> submitted by /u/Ok_Marionberry8922 (https://www.reddit.com/user/Ok_Marionberry8922)

Kafka Streams: The Complete Guide to Interactive Queries and Real-Time State Stores
https://www.reddit.com/r/programming/comments/1p83h3s/kafka_streams_the_complete_guide_to_interactive/

<!-- SC_OFF -->Hey all — I’ve been working on streaming systems lately (mostly for finance / real-time data pipelines), and one issue kept coming up: how do you efficiently query the state inside a streaming app while it’s running? So I wrote up a short guide to Kafka Streams’ interactive-query mode — how to store state via state-stores, and how to fetch current values at runtime (e.g. latest aggregates, sensor-level state, etc.). I tried to keep the write-up simple: minimal jargon, example code, and a clear walkthrough. If you’re building real-time dashboards, stateful event processing, or scalable microservices using Kafka Streams — I thought this might help.
