Re:Japan sees record drop in population on Monday April 14, 2025 @02:00PM (#43684249)
Hmm... US has 330 million. JP has 120 million in the size of california. They have a long way to go.
One company looking to capitalize on this is Onehouse, a three-year-old Californian startup founded by Vinoth Chandar, who created the open source Apache Hudi project while serving as a data architect at Uber. Hudi brings the benefits of data warehouses to data lakes, creating what has become known as a “data lakehouse,” enabling support for actions like indexing and performing real-time queries on large datasets, be that structured, unstructured, or semi-structured data.
The idea of running workloads on the cheapest compute platform is interesting.

About me:

My game is changing the world at warp speed. I've honed my skills across the board - sales engineer, developer advocate, lead developer, even infrastructure and operations maestro. Think of me as a multi-class strategist with 10 patents under my belt and 20+ certifications in my arsenal – Java, .net, you name it. I can build it, deploy it, talk the talk, and walk the walk, from bare metal to cloud-native code. So, what's the next challenge we'll tackle together?

I am looking for my next job in sales engineering or developer relations.

Data-warehousing becomes ubiquitous and open-source with Iceberg. Powerful open-source RTA (real-time-analytics) engines like ClickHouse are designed for crunching numbers as fast as possible. How can you use Iceberg and ClickHouse together to burn the rubber over glacially slow storage?

Ask HN: Looking for recommendations on Analytics tools for user behavior

Hello all, looking for recommendations on Analytics tools for user behavior. This would include link tracking and journeys where anonymous user data can be later tied to an account after sign-in. Common Room is an awesome tool and love to use it, but it doesn't do this at the moment.We have Amplitude, but didn't use it because the implementation costs, time and maintenance are too much.I know...

Ask HN: Tool to compare OSS communities to each other

I'm looking for help from the larger community. I'm looking for tools to help compare OSS communities to each other.I'll be even more specific. Say I'm an OSS OLAP database and I want to have as much mindshare as Trino. Is there a tool that can tell me how I compare my OSS product/community to theirs. I'm thinking along several dimensions.- Technical Parity: Focus on core functionality,...

intake of 450,000 entries per second, and a daily data volume of 12TB

* Query performance improved 4x. * Query P90 time improved from 500ms to 150ms. * The cluster size reduced from 60+ nodes to less than 10 nodes. * Data storage volume reduced by about 40%. * Overall cost reduced by more than 80%.

It is my belief that data lakehouse analytics will replace data warehouse analytics in the future. Data lakehouses offer a number of advantages over traditional data warehouses
Re: on Wednesday November 01, 2023 @06:48PM (#38106464)
Before we start, what is TPC-H and TPC-DS and why are they important?

TPC-H and TPC-DS are important because they are industry standard benchmarks for measuring the performance of data warehouse and big data systems. They are widely used by vendors and customers to evaluate the performance of different systems and to compare the performance of the same system over time.

It only works with Clickhouse... ugh.

Scale. DuckDB chokes at a certain point (just like sqlite isn't the same as mysql or postgresql in terms of scalability). That's why they're building a better/bigger version.

MongoDB did something similar. It's open source for you to extend and host yourself but you can't build a cloud service for it.

Lots of other competitors like Apache Pinot, Apache Druid and StarRocks are fighting in that default analytics space.
Re:Is ClickHouse Moving Away from Open Source? on Friday September 22, 2023 @03:38PM (#37616703)
All the main players in Clickhouse's space like Apache Pinot, Apache Druid, StarRocks, PrestoDB all have mindshare and unicorns using their products. It sounds like you haven't seen whats happening in this space.
Re:Is ClickHouse Moving Away from Open Source? on Friday September 22, 2023 @03:34PM (#37616656)
Here's a list of other open source OLAP systems out there. Clickhouse is on the list along with others like StarRocks. https://atwong.medium.com/top-open-source-alternatives-to-ol...
Re:The uses and abuses of Cloud Data Warehouses on Wednesday August 16, 2023 @12:35PM (#37149632)
There are other databases today that do real time analytics (ClickHouse, Apache Druid, StarRocks along with Apache Pinot). I'd look at the ClickHouse Benchmark to see who are the competitors in that space and their relative performance.

As a database engineer, people ask me all the time, “What is the hottest area of database design” right now. It’s using SIMD which stands for Single instruction, multiple data, to process a lot of data very, very fast.
Looking at https://landscape.cncf.io/card-mode?category=database, here’s a list of the online analytical processing (OLAP) that are CNCF members

Re:Neeva Acquired by Snowflake on Thursday May 25, 2023 @03:08PM (#36074740)
You could argue that it's an addon. OLAP databases just allow you to do SQL for analytical use cases.

Maybe not 100% but it did influence the decision on working for an open source company.
