squawk VS patroni

that is definitely the goal, both a formatter and a linter. we want to add something like squawk directly to the language server, so you get eslint-like dx. with the ast and the database schema in the data model, you can basically add any rule you like.

You can use a linter for PostgreSQL migrations https://squawkhq.com/

We've had good success with https://github.com/sbdchd/squawk to lint migrations. It tells you if a query is going to lock your table (as long as it's written in SQL, not some ORM DSL)

> I think etcd is basically a k8s only project now

I hate etcd with the best of them, but etcd is used in a lot more places than just kubernetes:

https://github.com/apache/apisix/blob/master/docs/en/latest/...

https://github.com/traefik/traefik#:~:text=Etcd,

https://github.com/zalando/patroni#patroni-a-template-for-po...

https://github.com/purpleidea/mgmt/tree/0.0.26/etcd (this one shows up on HN quite a bit)

https://github.com/sorintlab/stolon#features

It's actually one of the major reasons I wouldn't touch those projects

Citus doesn't provide fault tolerance. Each shard is a monolithic PostgreSQL. To reduce downtime on failures, you can protect each shard with a standby database. As this is a complex configuration, Patroni can help. For this lab I'll use the Citus+Patroni docker-compose-citus.yml from https://github.com/zalando/patroni.git:

We have been using stolon + consul for years without issue in our swarm environments. It may also be possible with patroni.

one of the solutions which made it pretty simple for us to run postgresql in a ha environment (mostly in k8s, but works standalone as well) is zalandos patroni: https://github.com/zalando/patroni it's really solid and worked for us for a few years already.

or for k8s their operator: https://github.com/zalando/postgres-operator (docker image: https://github.com/zalando/spilo) we've also tried other operators which were easier to get started, but they failed miserably (crunchyrolls operator is basically based on the zalando one)

Hello. I am currently using this docker-compose model from Zalando repository. It does not include PgBouncer in its architecture by default. I've been trying to find a containerized implementation involving Patroni, HAProxy, Etcd and PgBouncer. I didn't find anything solid so far.

General purpose: Patroni - Set up your own etcd + HAProxy + Patroni + Postgres components and it'll generally manage itself after that.

I don't have a great answer for you except that it sounds like you are trying to create your own version of patroni. Is there a good reason to not just use patroni?

git clone https://github.com/zalando/patroni.git cd patroni docker build -t patroni . docker-compose up -d
