It is common for free node services to aggressively rate limit requests. This impacts both backfill and incremental indexing.

For backfilling, it is advisable to use low values for batch_size and concurrency. For example: batch_size=10 and concurrency=1.

For incremental indexing, it is now advisable to increase the poll_duration for a source. For example: poll_duration=1s

Both of these knobs will reduce the amount of requests that are sent to a hosted node.
