Hello, it is possible do parallel filter via collection stream?

Are you talking about Java streams?

Okey, thx guys. I think mb in kotlin we have another way for it)

Another way is to use sequences, which is more idiomatic to Kotlin (or so I think), and achieves the same function as streams

If you use java streams there is no other way. You can achieve it using coroutines

Andrey, some samples? How i can make it with coroutines? Interesting

Depends on your case, there are different ways, I would recommend to check coroutines guides first

If you feel adventurous, you can take a look at flows: https://medium.com/@elizarov/cold-flows-hot-channels-d74769805f9 https://medium.com/@elizarov/kotlin-flows-and-coroutines-256260fb3bdb

Okay, thx now i have some ideas)

Just want to mention that Flow is not the only way, but yes Flow is most suitable abstraction for this. But again, I would recommend to read official guides first, to have understanding of coroutines
