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...
Is ClickHouse Moving Away from Open Source?

#52This would be a shame and also a mistake in my opinion. Clickhouse is instantly differentiated from Snowflake, Databricks, BigQuery and RedShift with the open source offering that you can deploy yourself. There are lots of other options but Clickhouse has the most mindshare and is the techies choice. I find myself rooting for them and recommending them for that before you even get into any technical comparison.
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.

i appreciate your work here man, altinity even wrote a lot of useful blog posts about clickhouse back then, love those stuff. this whole thing reminds me of elastic and hashicorp, and it's hard to pick sides given that the core maintainers also worked their assess of building it in public, and the community contributors also put their effort into it. i think this common theme is unlocking a new era of software where…
Thanks. That's exactly why we wrote the article. Beyond any commercial considerations, we have worked with ClickHouse for many years and are personally invested in seeing it become the default analytic database worldwide. I believe the best path to that goal is robust support for open source development and distribution.
Lots of other competitors like Apache Pinot, Apache Druid and StarRocks are fighting in that default analytics space.

#54The blog author founded altinity. Altinity's main product offering is a hosted clickhouse service. The top 10 committers to clickhouse all seem to be clickhouse employees. Looking at altinity on github, they contribute much less open source. If clickhouse the company are spending 40%+ of their money to build the product, then others including altinity spend 5% dev and 80% marketing, they will get more customers. That…
"A license that doesn’t allow reselling the service is good enough For example, I saw this with Tailwind UI" FYI, we discussed it in this thread https://github.com/ClickHouse/ClickHouse/issues/44767 . For the moment, the only way to get the new features is to use the cloud version (which is likely to be a no-go for most companies managing their own clickhouse infrastructure).
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.

#55As a user of clickhouse since 2018 I'm fully aligned with the content of this article. This technology is one of the best I've been using in my career. The choice of clickhouse for a new project in my company has always been a no-brainer, but the recent move from clickhouse.inc to a closed source version has made this choice less straightforward.

#56How do you chose between ClickHouse and DuckDB ? It feels like they solve the same problem
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.

ClickHoues is also faster than any of them if you know how to use it properly. It helps if you have some distributed systems background and an intuitive feel for map/reduce. For example ReplacingMergeTree uses a distributed algorithm to process changes without incurssing excessive INSERT time expense. It's quite elegant.
Insert should hav never been expensive in the first place. This was probably hard for clickhouse because they started with postgres as the base which is optimized for oltp. In apache Pinot/druid etc, insert is nothing more than a simple append and believe thats the case today with clickhouse as well... In other words, these things are table stakes today and are not differentiators.

This is a different problem. Update is expensive in distributed columnar data. ReplacingMergeTree translates updates into inserts which are very fast and always have been. It then updates rows in a lazy fashion.

#59Open Source doesn’t pay. Companies need to make money. Any open source product owned and developed by a for profit company is at danger of it moving away from open source.
If you want open source go fund non profit organisations and/or charities. The fact we don’t see developers do that tells me a lot.

Are you part of ClickHouse community, ever used that DBMS or participate in any activity related it? Just to make sure, we are on the same page.
Yes I am part of the community. Yes I have used clickhouse for many years now. Yes I have recommended clickhouse to a number of others and helped them personally get started. I think it's a great piece of technology.
In that case, you should know what is Altinity.
