How to handle flushing buffer behavior in Airbyte

[Vladislav Bakanov (vladislav-bakanov)]

Environment:
Source connector: Slack (3.1.6)
Destination: S3

Context:
I have a Slack connector, where I see that it makes flushing the buffer every 5 min, because my batches in the source are quite small (few kb).
I guess the mechanic of processing batches in Airbyte quite similar to what Kafka Connect, where you wait for duration to flush or you wait until the required volume of the buffer is reached and you can manage such behavior of buffer.

Question:
Is't possible somehow to manage buffer size / flush interval in Airbyte?
