Hi all, co-founder of Timeplus here. One of our community users tried the 1brc. At the core, Timeplus is a streaming processor, powered by ClickHouse. So it can leverage thousands of powerful SQL functions from ClickHouse, including `file(f

Love ClickHouse and Kafka? Let Timeplus Proton take it to the next level. Proton is an open-source streaming processor, written in C++. We’re thrilled to introduce a major upgrade of Proton, which you can now read or write ClickHouse with s

I've been using Arc since June 2023. I really like it as a product. But the communication is a bit overwhelming. Their CEO and team are fairly good to make noise (in the good way) on YouTube, twitter. But I guess I cannot catch up with

Glad to hear that. In the Timeplus Cloud UI, there is a way to visualize the query plan/DAG. Sorry it's not available in command line yet.

SQL is so flexible. When I put myself as a user, I also prefer those tools that provide nice UI for filter/reporting, but also give me SQL interface to do advanced query, such as PostHog, Resmo, JIRA(?)

it's a spicy question.. The full comparison deserves one or a series of blogs In short, data streaming is getting popular. Apache Flink, Apache Spark, ksqlDB are traditional players. They work well in some cases, but have challenges on

Nice intro, but I am a bit worried not seeing SOC2 or something similar.

Thanks for the feedback (I am part of the Timeplus team) https://docs.timeplus.com/showcases lists a few real world use cases we solve with our customers. Proton is core engine of Timeplus Cloud, which adds extra UI, source

Yes, that's a cool project. I won't miss any Proton update on my Steam Deck, and sometimes we got signups from proton mail too

Thanks for letting us know. Technically it's not Apache Proton. The link is the Proton component in Apache Qpid. Maybe we should setup a list for awesome Proton(s)

How about "Timeplus Proton"? Yes, I know there are good game engine and mail service with that name. At Timeplus, component is named after the particles, e.g. https://github.com/timeplus-io/chameleon , our dat

yes, it's more an alternative to FlinkSQL. SQL is the main interface, and you can also build User-Defined Function with JavaScript, running in sandbox with V8. While Flink DataStream or Table API are powerful and flexible, you can easi

500MB is the binary size, when you download proton from the GitHub release page. Also available as a docker image. The memory consumption can be 200MB or a few GB, depending on the workload. Comparing to setup Flink/ksqlDB with JVM, Pr

The overall setup process was great. I can simply use the latest Grafana docker image, and use the environment variable to install the extra plugin (timeplus-proton-datasource) and load pre-defined data source and dashboards as yaml. Grafan

Python + SQL, a match made in heaven! You can run `docker compose up` to get everything up running within few minutes. Or check this public demo server at http://hn.demo.timeplus.com/d/d299c092-7bda-4a37-ba1d-5f484f...

It's not hard to guess the pricing page URL. It seems that MotherDuck is not ready to announce it. Cold Storage is $40 per TB (close to many S3 based offering). But I have problem to understand the Hot Storage: $0.02 per GB per hour. I
