Putting json format records to kinesis, it runs for some time and then start producing warning for retry.
No idea what's going wrong behind the scene.

This warning message means that PutRecords API of Kinesis Data Streams or PutRecordBatch API of Kinesis Data Firehose returned failed records because of some kind of error, such as ProvisionedThroughputExceeded.

Gem code:

aws-fluent-plugin-kinesis/lib/fluent/plugin/kinesis_helper/api.rb

Lines 89 to 109 in d5d7c69

def batch_request_with_retry(batch, retry_count=0, backoff: nil, &block)
backoff ||= Backoff.new
res = yield(batch)
if failed_count(res) > 0
failed_records = collect_failed_records(batch, res)
if retry_count < @retries_on_batch_request
backoff.reset if @reset_backoff_if_success and any_records_shipped?(res)
wait_second = backoff.next
msg = 'Retrying to request batch. Retry count: %3d, Retry records: %3d, Wait seconds %3.2f' % [retry_count+1, failed_records.size, wait_second]
log.warn(truncate msg)
# TODO: sleep() doesn't wait the given seconds sometime.
# The root cause is unknown so far, so I'd like to add debug print only. It should be fixed in the future.
log.debug("#{Thread.current.object_id} sleep start")
sleep(wait_second)
log.debug("#{Thread.current.object_id} sleep finish")
batch_request_with_retry(retry_records(failed_records), retry_count+1, backoff: backoff, &block)
else
give_up_retries(failed_records)
end
end
end

Kinesis API reference:
https://docs.aws.amazon.com/kinesis/latest/APIReference/API_PutRecords.html
https://docs.aws.amazon.com/firehose/latest/APIReference/API_PutRecordBatch.html

Can you check your cloud side metrics by CloudWatch?

Also wondering can we do firehose put directly with aggregated records

Currently, we cannot put aggregated records directly into firehose. Appreciate your feedback. See also this issue #193.
