Hi @malomz, I'm one of the maintainers of the
mongodbcrate. Thanks for writing up this tutorial!I wanted to point out that since you are writing an asynchronous application (as Actix is an async framework), it would be most appropriate to use the mongodb
asyncAPI here rather than the sync API. With the sync API, every time you interact with the database you will be running blocking code on the current thread and preventing the async runtime (Tokio) from scheduling any other async tasks on the thread while waiting for a response from the database. The end result is that your application is more resource-intensive and less performant, since threads cannot be shared as efficiently.With the async API, the thread can be "given up" to another task while you
awaitthe response from the database.This is a nice blog post on this subject.
The async API is identical to the sync one besides everything being
async; to adopt your example here I think you'd just need to mark the methods on yourMongoRepotypeasyncand call the equivalent async mongodb API methods.You can find a simple example of using the async mongodb API with actix here.
Feel free to get in touch with us via GitHub if you have any questions or run into any issues.
Hi @kmahar ,
Thanks for pointing this out 🙏🙏.
I have updated accordingly👍
Awesome! One more thing to note is that since Actix uses the tokio runtime, I'd suggest using the driver with tokio as well, rather than async-std, so that you do not need to have two separate runtimes going that cannot coordinate with one another.
By default the mongodb crate uses tokio, so to do this, you can just remove these lines from your Cargo.toml:
There's some documentation on all of the drivers' feature flags available here.
I expect to see more people start to use rust + postgres + an ORM, when they want something with a richer type system or more functional idioms than go, python, or node/ts. Do you think that emerge and possibly reach fourth place over ruby for web dev?
Well, rust is relatively new to the ecosystem as compared to others. Hopefully, it becomes mainstream! :)
hi there, just wanna collection ppl opinion but could I ask why you choose Postgres over Mongodb when stack with Rust or actix-web for more specific? TIA
As I understand, postgres will be easier to implement a wide variety of queries, while mongo will help keep inserts fast, so having more flexibility with queries may be a good default.
Thanks for putting the effort to write this amazing post definitely will try Actix Web soon 😁
Glad you enjoyed it.
Yea, you should give it a try!
Thank you for this tutorial
Thanks!
Good article, thank you.
AWESOME!! Thanks for this ammount of knowledge shared. I really appreciate it!
Glad you enjoyed it!
nice post thanks @malomz for the nice guide and thanks @kmahar for feedback.
Thanks for your article. I have a question. Suppose after creating the client if you want to store it in global variables for further use how I can do that?
How would you model the MongoRepo struct if you have multiple collections?
