I was wondering the same, but I'm not sure if it would make a major change in the graphs. MySQL and MariaDB have both been unpopular on Hacker News for many years. Submissions on either topic rarely get much traction, which then leads to fewer submissions.

> MySQL trending downwards would make sense as people upgrade and switch over.

No, most large MySQL users are still using MySQL; there hasn't been a widespread migration to MariaDB. They're both actively developed and have grown in slightly different directions. Among corporations, MySQL's usage still far outstrips MariaDB by a significant degree. Lately MariaDB has better product velocity though, and their commercial enterprise finally seems to have stable footing.

It's really fantastic. Continuously updated and fast anonymous queries. Big kudos to ClickHouse.

There are some people here who are interested in corporate Europe or <insert Microsoft foothold place/industry here>, but most are aligned with Silicon Valley hackers.

Something that I’ve been thinking about a lot recently is that all of the proprietary vendors are quietly strangling their flagship products.

Free and open source database engines were always “nipping at their heels” but weren’t a serious threat for decades. Only other proprietary engines were.

Now that PostgreSQL has more features than SQL Server and better performance, it’s a serious competitor.

But Microsoft is holding MSSQL’s face under water with core-based licensing. It means that per dollar you get dozens of times less compute available for your data than with open-source systems. That ratio is growing exponentially, because they haven’t redone their pricing in… ever.

Oracle and DB2 are being similarly choked off at the same rate, so looking left and right at their direct competition their respective product managers haven’t noticed the problem, which is akin to Fuji and Kodak raising film prices in lockstep just as digital photography is taking off.

We’re entering the era of “kilocores”: single servers becoming available that have over a thousand cores. You can’t imagine what per-core licensing costs for something like that!

PS: I saw a similar dynamic play out in the network space with load balancers and “web accelerators” like NetScaler sold “by bandwidth” with a starter SKU as small as 2 Mbps. I kept trying to politely explain to the reps that the smallest cloud VMs can cheerfully put out 10 Gbps, and hence their product is a 500x decelerator. They eventually listened to someone and made it bandwidth-unlimited. Too late. Everyone uses NGINX now.

Does play.clickhouse contain all the HN data so that we can play with it?

It doesn't though, all it tells you is that it's missing from the headlines in the submissions.

"Enterprise" is discussed on HN too, but inside submissions that aren't exclusively about MS Sql Server. Try searching for some terms on the Algolia HN search, order by date and filter by comments and you'll find the subthreads/submissions where it's discussed :)
