  • Using ClickHouse to scale an events engine
    5 projects | news.ycombinator.com | 11 Apr 2024
    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
    6 projects | news.ycombinator.com | 19 Sep 2023
    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.

    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
