is it worth calling the asSequence funtion like this kinesisEvent.records.asSequence() before calling foreach in this example:

// event: List<KinesisEvent.KinesisEventRecord>

 event.records.forEach {
            try {
                val putRecordsRequest = PutRecordsRequest()
                putRecordsRequest.streamName = "test-stream" 
                val putRecordsRequestEntryList = ArrayList<PutRecordsRequestEntry>()
                for (i in 0..499) {
                    val putRecordsRequestEntry = PutRecordsRequestEntry()
                    putRecordsRequestEntry.data = it.kinesis.data
                    putRecordsRequestEntry.partitionKey = it.kinesis.partitionKey
                    putRecordsRequestEntryList.add(putRecordsRequestEntry)
                }
                putRecordsRequest.setRecords(putRecordsRequestEntryList)
                val putRecordsResult = kinesisClient.putRecords(putRecordsRequest)

            } catch (e: InterruptedException) {
                //log error here
            }

No. I don't think so since foreach is just getting an Iterator and calling next() so no transform like when mapping etc..

Afaik asSequence will only be beneficial when doing multiple processing steps in between

Or dealing with an infinite stream.
