Since the Timescale License is not an open source license, it is a closed source license. You are right, it is source available, but source available is also closed source. It is closed because it is not open. And it might be free as in beer, but it is not free as in freedom.
My recollection is that the TS license simply has protection against using the TS code to compete with TS, ala Amazon RDS. While some people on HN feel that this is an impurity they can’t live with, I personally think it’s a small price to pay to enable development of TS to continue. In my opinion, claiming that it’s closed source is somewhat dogmatic. Many open source licenses have some kind of restrictions on use;…
I have always been more on the pragmatic side of the FOSS movement (open source versus the philosophical/moral stance of the FSF, but still have tremendous respect for the FSF). For pragmatic reasons I reject the Timescale License. It doesn't just prevent Amazon (that alone would be misguided enough, though) but also prevent anyone other than Timescale from hosting the software for me. That means even if Timescales current offerings lined up perfectly with my business, I would be locked into whatever decisions they make in the future which may not align. The chances for a successful community fork are greatly reduced under the restrictions of the Timescale license. It makes it impossible for the community to make contributions on equal footing to Timescale, thus anyone making contributions are just doing free work for a corporation, rather than contributing to a product the community benefits from just as much as the corporation.

Ah, I suppose you'd prefer they switched to Affero GPL v3 (which BTW IS open source and written by FSF itself) - check it out here: https://www.gnu.org/licenses/agpl-3.0.en.html This license turns out to be very difficult to use for almost developer.
I prefer the Apache or Mozilla Public Licenses myself. But I accept the AGPL and the GPL family of licenses will consider useing software licensed under them in limited ways (it isn't clear how the AGPL interacts with infrastructure software).

What did you use to collect and injest the metrics?
Re: TimescaleDB 2.7 vs. PostgreSQL 14
#56Whenever I see these posts from TimescaleDB, I always want to ask them how it compares in performance to alternative extensions that implement the same features, rather than just comparing TimescaleDB to vanilla PostgreSQL. For example, they mention their automated data retention and how it's achieved with one SQL command, and how DELETEing records is a very costly operation, and how "even if you were using Postgres…
Seconded. I understand that Timescale extends Postgres, but I'd still like to see performance comparisons relative to other time-series databases such as InfluxDB or even TiDB. Shameless self-plug: we're also building database technology, but for embedding vectors ( https://milvus.io ) rather than time-series data - when doing query performance comparisons, we get several orders of magnitude of performance improvemen…
Once I've read this, I never had to think twice on what to use.
