@@ -59,6 +59,7 @@ password | No | String | Password for HTTP basic authentication.
 aws_sigv4 | No | Boolean | Default value is false. Whether to use AWS Identity and Access Management (IAM) signing to connect to an Amazon OpenSearch Service domain. For your access key, secret key, and optional session token, Data Prepper uses the default credential chain (environment variables, Java system properties, `~/.aws/credential`, etc.).
 aws_region | No | String | The AWS region (for example, `"us-east-1"`) for the domain if you are connecting to Amazon OpenSearch Service.
 aws_sts_role_arn | No | String | IAM role that the plugin uses to sign requests sent to Amazon OpenSearch Service. If this information is not provided, the plugin uses the default credentials.
+max_retries | No | Integer | The maximum number of times the OpenSearch sink should try to push data to the OpenSearch server before considering it as failure. Defaults to `Integer.MAX_VALUE`. If not provided, the sink will try to push data to the OpenSearch server indefinitely because the default value is high and exponential backoff would increase the waiting time before retry.
 socket_timeout | No | Integer | The timeout, in milliseconds, waiting for data to return (or the maximum period of inactivity between two consecutive data packets). A timeout value of zero is interpreted as an infinite timeout. If this timeout value is negative or not set, the underlying Apache HttpClient would rely on operating system settings for managing socket timeouts.
 connect_timeout | No | Integer | The timeout in milliseconds used when requesting a connection from the connection manager. A timeout value of zero is interpreted as an infinite timeout. If this timeout value is negative or not set, the underlying Apache HttpClient would rely on operating system settings for managing connection timeouts.
 insecure | No | Boolean | Whether or not to verify SSL certificates. If set to true, certificate authority (CA) certificate verification is disabled and insecure HTTP requests are sent instead. Default value is `false`.
