Open-Source C++ Apache Iceberg Client with Write Support
Existing OSS C++ projects like ClickHouse and DuckDB support reading from Iceberg tables. Writing requires Spark, PyIceberg, or managed services. In this PR https://github.com/timeplus-io/proton/pull/928, we are open-sourcing a C++ implementation of Iceberg integration. It's an MVP, focusing on REST catalog and S3 read/write(S3 table support coming soon). You can use Timeplus to continuously read data from MSK and stream writes to S3 in the Iceberg format. No JVM. No Python. Just a low-overhead, high-throughput C++ engine. Docker/K8s are optional. Demo…

What it does
The Fastest Unified Streaming SQL Engine in a Single C++ Binary. ⚡ Millisecond latency. 100+ GB/s throughput. Continuously compute real-time context from streams, logs, metrics, events, and CDC. - Add Apache Iceberg Streaming Writes and Batch Reads (MVP) by zliang-min · Pull Request #928 · timeplus-io/proton
This PR introduces MVP-level support for streaming writes and batch reads with Apache Iceberg tables, fully implemented in C++ (no JNI). While existing C++ projects like ClickHouse and DuckDB focus on read-only Iceberg integration, this implementation adds native write capabilities, enabling end-to-end data pipelines directly from SQL. -- Connect to a Iceberg database managed by AWS Glue, using AK/SK/IAM from the host CREATE DATABASE demo SETTINGS type = ' iceberg ' , warehouse = ' (aws-12-id) ' , catalog_type = ' rest ' , catalog_uri = ' https://glue.us-west-2.amazonaws.com/iceberg ' , storage_endpoint = ' https://bucket.s3.us-west-2.amazonaws.com ' , rest_catalog_sigv4_enabled = true,…from github.com

C++ AWS MSK IAM Auth Implementation – Goodbye Kafka Passwords2025 · github.com · ▲50In 2023, AWS announced[1] IAM authentication for MSK Kafka clusters with support for "all programming languages"… except C++. While Java[2], Python[3], Go[4], and others got official SDKs, C++ developers/vendors were stuck hardcoding SCRAM-SHA credentials in code/configs or relying on heavier Java-based tools like Kafka Connect or Apache Flink. Later, community projects added Rust[5] and Ruby[6] support. Why no C++? Rust might be the new favorite, but C++ is still king for high-performance data systems: minimal dependencies, lean resource use, and raw speed. At Timeplus, we needed…

Open-source, browser-local data exploration using DuckDB-WASM and PRQL2024 · github.com · ▲227Hey HN! We’ve built Pretzel, an open-source data exploration and visualization tool that runs fully in the browser and can handle large files (200 MB CSV on my 8gb MacBook air is snappy). It’s also reactive - so if, for example, you change a filter, all the data transform blocks after it re-evaluate automatically. You can try it here: https://pretzelai.github.io/ (static hosted webpage) or see a demo video here: https://www.youtube.com/watch?v=73wNEun_L7w You can play with the demo CSV that’s pre-loaded (GitHub data of text-editor adjacent projects) or upload…

OpenObserve – Elasticsearch/Datadog alternative2023 · github.com · ▲198Hello folks, We are launching OpenObserve. An open source Elasticsearch/Splunk/Datadog alternative written in rust and vue that is super easy to get started with and has 140x lower storage cost compared to elasticsearch. It offers logs, metrics, traces, dashboards, alerts, functions (run aws lambda like functions during ingestion and query to enrich, redact, transform, normalize and whatever else you want to do. Think redacting email IDs from logs, adding geolocation based on IP address, etc). You can do all of this from the UI, no messing up with configuration files. OpenObserve…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
