</match>

Usage notes

If you'd like to retry failed requests, consider using fluent-plugin-bufferize. Or, specify appropriate recoverable_status_codes parameter.

To send events with bulk_request, you should specify bulk_request as true Note that when this parameter as true, Fluentd always send events as application/x-ndjson. Currently, application/x-ndjson is only supported MIME type for bulk_request.
