Is there a more idiomatic way to do the following operation? Thank you!
it.receiver can either be of type ABC or DEF. If its ABC, collect to the first list, if its DEF, collect to the second list

val payments = findOpenPayments.get()
                .groupBy { it.receiver == "ABC" }

        val somePayments = payments.filter { it.key }.flatMap { it.value }
        val otherPayments = payments.filter { !it.key }.flatMap { it.value }

You can do something like this,

val payments = findOpenPayments.get()
                .groupBy { it.receiver }

This will result in a HashMap of 2 keys ABC and DEF , from which you can obtain the value. Hope this helps

perfect. Thanks!

if there are only two possible values for receiver, you can do

val (somePayments, otherPayments) = openPayments
    .partition { it.receiver == "ABC" }

Yep this works as well

That's also a great one. Thank you!
