Lago, Open-Source Stripe Alternative, banks $22M in funding
We shared a few thoughts about « why oss does not win by being cheaper », we are trying o find the balance between oss, quality, sustainability, indeed.

It got a fair share of comments on HN as well https://news.ycombinator.com/item?id=37682684

Lago Is Hiring to Scale the Open-Source Alternative to Stripe Billing

Reach out at [email protected] or directly through https://www.ycombinator.com/companies/lago/jobs
Last but not least: we’ve historically took a little bit too much time to answer applications (we’re still a small team), and I’d like to personally apologize for this.

Using ClickHouse to scale an events engine
Don't feel bad, lots of people get bitten by not reading all the way down to the bottom of their readme: https://github.com/hydradatabase/hydra/blob/v1.1.2/README.md... While Hydra may very well license their own code Apache 2, they ship the AGPLv3 columnar which to my very best IANAL understanding taints the whole stack and AGPLv3's everything all the way through https://github.com/hydradatabase/hydra/blob/v1.1.2/columnar/...

Moving a Billion Postgres Rows on a $100 Budget
Columnar store PostgreSQL extension exists, here are two but I think I’m missing at least another one:
https://github.com/citusdata/cstore_fdw
https://github.com/hydradatabase/hydra
You can also connect other stores using the foreign data wrappers, like parquet files stored on an object store, duckdb, clickhouse… though the joins aren’t optimised as PostgreSQL would do full scan on the external table when joining.

Show HN: Hydra - Open-Source Columnar Postgres
some previous discussions:
https://news.ycombinator.com/item?id=37247945
https://news.ycombinator.com/item?id=36987920
and a relevant observation is that there are actually multiple license files in the repo so the consumer should read their explicit licensing section of the readme <https://github.com/hydradatabase/hydra#license> since the GitHub sidebar is misleading

CDC from postgres to postgres.
Hydra DB Link to Github -> Worked well for aggregated query usecases but not for queries that build reports. Also, data insertion and updation is abyssmal on columnar dbs.

How Query Engines Work
There's a lot of experience about db operation and how to approach MVCC encoded in PostgreSQL that shouldn't be underestimated.

Hydra: Column-Oriented Postgres
And just like last time, watch out for the misleading GitHub license detector because it's not entirely Apache as the GitHub summary claims but rather *some* is Apache and buried in the interior is some AGPL stuff: https://github.com/hydradatabase/hydra#license
