Kotlin: Split Sequence&lt;T&gt; by N items into Sequence&lt;Sequence&lt;T&gt;&gt;?
How to "take(N)" iteratively - get a Sequence, each inner sequences having next N elements?
I am writing a high-load application in Kotlin.
I have tens of thousands of entries to insert to a database.
I want to batch them by, say, 1000.
So I created a loop:
val itemsSeq = itemsList.iterator().asSequence()
while (true) {
log.debug("Taking $BATCH_SIZE from $itemsSeq")
val batchSeq = itemsSeq.take(BATCH_SIZE)
val squareBatch = applySomething(batchSeq, something)...
