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

[gildor]

Are you talking about Java streams?

[gildor]

There is parallel() operator for java streams

[Alexjok]

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

[Krotick]

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

[gildor]

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

[gildor]

Kotlin sequences is syncronous only abstraction, there is no way to make it parallel, at least in some easy way without some fork-join abstraction

[Alexjok]

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

[gildor]

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

[Krotick]

If you feel adventurous, you can take a look at flows:

Okay, thx now i have some ideas)

[gildor]

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
