Please free us of kdb
Why? I'm genuinely curious, since I've never worked with kdb but I've often heard great things about it (regardless of the weird query language).
Kdb is like oracle db that somehow won’t die. It could use some competition

#12We switched from Datomic to Timescale and haven’t looked back.

Good old HN with its healthy skepticism :)
Re: TimescaleDB raises $40M
#14I'm pretty stoked for this. Timescale ability to use time series on a subset of tables (hypertables) really makes it an interesting choice. I've just dabbled with it but seeing that they'll finally be improving their hosted solution make me want to dive in deeper! Anyone has experience running large DB on timescale, would you recommend it?
If you end up transitioning to multinode deployments from a single node deployment, there are a bunch of tradeoffs to consider.
A good reference point for this to check out the `multinode` label in their github issues. https://github.com/timescale/timescaledb/labels/multinode
One of the big items that stood out to me is the inability to be able to migrate data from an existing table when creating a distributed hypertable. There were also some significant query performance reports as well.
These all may improve with time of course, so watching the dev cycles will give you a good sense of that I think.

#15Very happy with our choice to use TimescaleDB. The idea to simply make it a Postgres extension was brilliant. The compression release was one of the cooler features I've seen in recent times. Row database for recent transactional data, columnar compressed database for historical OLAP workloads - pretty much automagically.
Curious how large a dataset you're using?

#16I was in Grand Central Tech with the Timescale folks, became friends with both Ajay and Mike. Ajay gave me a lot of good thoughts on building my startup(thanks!), and Mike is..well.. just hyper smart. That is to say, I'm not surprised to read this and for what it's worth: they deserve it, really great humans! :)

TimescaleDB isn't an alternative to KDB+. KDB+ is more a programming platform than a database.
Re: TimescaleDB raises $40M
#18This is awesome. In certain industries (manufacturing, energy, etc) there are companies (really 1 company) that essentially have monopolies on time series databases / historians. There has been 0 competition in that space and as a result the databases and surrounding client tools are just so awful. It'll be interesting to see if timescaledb can really enter that market and force those companies to adapt.

I think it goes to show how impossible it is to judge an idea. YC itself doesn't pretend to do this with the ~15,000 applications they go through each cohort. They try instead to look at the team, look at their progress, imagine what would need to happen for the company to succeed at the level required for them to get the returns they seek.
Founders should have a thick skin when it comes to criticism on HN, because we don't know either.

#20We used TimescaleDB for a flood prediction tool, works really well, kudos.
