Beefinon Ask HN: Do you still use MongoDB?

Atlas makes sharding easier, it's just one button where you define your partition key.

Beefinon Ask HN: Do you still use MongoDB?

why not just do a covered query with aggregate pipeline via $match and $project, hitting all your indexes, then pipe the results to $count.

Beefinon Ask HN: Do you still use MongoDB?

Yes, use it with Atlas for every one of my companies' projects.

- The document model is a no-brainer when working with JS on the front-end. I have JSON from the client, and Dictionaries on the backend (Flask), so it's as easy as dumping into the DB via the pymongo driver. No object relational mapping.

- Can scale up/down physical hardware as needed so we only pay for what we use

- Sharding is painfully easily, with one click

- Support has been incredible

Beefinon Ask HN: Do you still use MongoDB?

much of the anti-mongo sentiment is around people who used it in 2009-ish.

it's useful to point out that when using the early version of any software, there will be bugs. that's a trade-off early adopters always need to contend with. unfortunately, it hasn't sat well over time despite every one of the concerns being addressed since.

Beefinon Ask HN: Do you still use MongoDB?

jsonb is limited in it's querying capabilities. you're essentially casting the json as a string when storing and querying, it's not truly json. therein lies the advantage of document model, native secondary indexes, $<queries> for everry nested layer, etc.

because it defies first principles logic. you should know in some capacity what's going on behind the scenes, and Op's point is that Flask forces you to understand that.

threadlocals = app.context ?

Agreed, but that's the beauty of Flask you can just pass around the request context.

Glad to see Flask surpass Django, it's always been my favorite web framework regardless of language and forces users to learn their style of software architecture. I personally prefer MVC: https://github.com/esteininger/flask-mvc-boilerplate

Beefinon Build Software from Front-to-Back

all software is build for users, and users interact with the front end. it makes sense to define the requirements with the front end and iterate until its ideal before starting any backend.

Beefinon San Francisco Residents Are Leaving at an Unprecedented Rate

isn't one of the core tenants of buddhism to seek enlightenment through non-reaction? It'd be ironic if they were indeed offended by this name. I don't think the name or intent behind the name contains any malice either.

look beyond the surface and understand the intent. Are they intending malice? yes thats offensive, if not then carry on and stop signaling :)

Beefinon Instacart announces new Covid-19 policies and plans to hire 250k more shoppers

Beefinon Comparison of Joins: MongoDB vs. PostgreSQL

In an ideal world yes, you only manage one database but no such "jack of all trades" DB exists for the same reason the CAP theorem remains true.

If your Postgres JSON schema modified for new application requirements, the table is locked until existing data is copied into the new schema, requiring applications to be quiesced during schema migration.

Thats a key difference between the two and one area Mongo performs best in.

Beefinon Comparison of Joins: MongoDB vs. PostgreSQL

have you tried using the postgres json data type? it's a joke.

Beefinon Comparison of Joins: MongoDB vs. PostgreSQL

When you don't want to use an ORM, want to scale horizontally, want to use BSON data types and all the indexing capabilities around them, etc.

Beefinon Comparison of Joins: MongoDB vs. PostgreSQL

None of that matters because your data needs to be modeled around your application usage patterns. If you maintain inter-collection relationships via Joins in Mongo just as if you were in Postgres, you're not doing it right.

Beefinon Why Is the Stock Market Booming?

My thought is that the majority of the markets rely on high frequency trading algorithms, which base their models off historical data. Given this is unprecedented times, the models are going haywire because nothing fits.

Beefinon Comparison of Joins: MongoDB vs. PostgreSQL

this isn't always true there are plenty of schema designs for storing data based on your application's usage patterns.
