notification_type | Yes | String | Must be `sqs`
compression | No | String | The compression algorithm to apply: `none`, `gzip`, or `automatic`. Default is `none`.

on_error | No | String | Determines how to handle errors in Amazon SQS. Can be either `retain_messages` or `delete_messages`. If `retain_messages`, then Data Prepper will leave the message in the SQS queue and try again. This is recommended for dead-letter queues. If `delete_messages`, then Data Prepper will delete failed messages. Default is `retain_messages`.

records_to_accumulate | No | Integer | The number of messages that accumulate before writing to the buffer. Default is 100.
metadata_root_key | No | String | Base key for adding S3 metadata to each Event. The metadata includes the key and bucket for each S3 object. Defaults to `s3/`.
disable_bucket_ownership_validation | No | Boolean | If `true`, the S3Source will not attempt to validate that the bucket is owned by the expected account. The expected account is the same account that owns the SQS queue. Defaults to `false`.

maximum_messages | No | Integer | The maximum number of messages to receive from the SQS queue in any single request. Default is `10`.
