This is the reference for Data Prepper configuration files (data-prepper-config.yaml). These are general Data Prepper configurations independent from pipelines.
Data Prepper server options
| Option | Required | Type | Description |
|---|---|---|---|
| ssl | No | Boolean | Indicates whether TLS should be used for server APIs. Defaults to true. |
| keyStoreFilePath | No | String | Path to a .jks or .p12 keystore file. Required if ssl is true. |
| keyStorePassword | No | String | Password for keystore. Optional, defaults to empty string. |
| privateKeyPassword | No | String | Password for private key within keystore. Optional, defaults to empty string. |
| serverPort | No | Integer | Port number to use for server APIs. Defaults to 4900. |
| metricRegistries | No | List | Metrics registries for publishing the generated metrics. Currently supports Prometheus and CloudWatch. Defaults to Prometheus. |
| metricTags | No | Map | Key-value pairs as common metric tags to metric registries. The maximum number of pairs is three. Note that serviceName is a reserved tag key with DataPrepper as default tag value. Alternatively, administrators can set this value through the environment variable DATAPREPPER_SERVICE_NAME. If serviceName is defined in metricTags, that value overwrites those set through the above methods. |
| authentication | No | Object | Authentication configuration. Valid option is http_basic with username and password properties. If not defined, the server does not perform authentication. |
| processorShutdownTimeout | No | Duration | Time given to processors to clear any in-flight data and gracefully shut down. Default is 30s. |
| sinkShutdownTimeout | No | Duration | Time given to sinks to clear any in-flight data and gracefully shut down. Default is 30s. |
| peer_forwarder | No | Object | Peer forwarder configurations. See Peer forwarder options for more details. |
Peer forwarder options
The following section details various configuration options for peer forwarder.
General options for peer forwarding
| Option | Required | Type | Description |
|---|---|---|---|
| port | No | Integer | The peer forwarding server port. Valid options are between 0 and 65535. Defaults is 4994. |
| request_timeout | No | Integer | Request timeout for the peer forwarder HTTP server in milliseconds. Default is 10000. |
| server_thread_count | No | Integer | Number of threads used by the peer forwarder server. Default is 200. |
| client_thread_count | No | Integer | Number of threads used by the peer forwarder client. Default is 200. |
| max_connection_count | No | Integer | Maximum number of open connections for the peer forwarder server. Default is 500. |
| max_pending_requests | No | Integer | Maximum number of allowed tasks in ScheduledThreadPool work queue. Default is 1024. |
| discovery_mode | No | String | Peer discovery mode to use. Valid options are local_node, static, dns, or aws_cloud_map. Defaults to local_node, which processes events locally. |
| static_endpoints | Conditionally | List | A list containing endpoints of all Data Prepper instances. Required if discovery_mode is set to static. |
| domain_name | Conditionally | String | A single domain name to query DNS against. Typically, used by creating multiple DNS A Records for the same domain. Required if discovery_mode is set to dns. |
| aws_cloud_map_namespace_name | Conditionally | String | Cloud Map namespace when using AWS Cloud Map service discovery. Required if discovery_mode is set to aws_cloud_map. |
| aws_cloud_map_service_name | Conditionally | String | Cloud Map service name when using AWS Cloud Map service discovery. Required if discovery_mode is set to aws_cloud_map. |
| aws_cloud_map_query_parameters | No | Map | Key-value pairs to filter the results based on the custom attributes attached to an instance. Only instances that match all the specified key-value pairs are returned. |
| buffer_size | No | Integer | Max number of unchecked records the buffer accepts. Number of unchecked records is the sum of the number of records written into the buffer and the num of in-flight records not yet checked by the Checkpointing API. Default is 512. |
| batch_size | No | Integer | Max number of records the buffer returns on read. Default is 48. |
| aws_region | Conditionally | String | AWS region to use ACM, S3 or AWS Cloud Map. Required if use_acm_certificate_for_ssl is set to true or ssl_certificate_file and ssl_key_file is AWS S3 path or discovery_mode is set to aws_cloud_map. |
| drain_timeout | No | Duration | Wait time for the peer forwarder to complete processing data before shutdown. Default is 10s. |
TLS/SSL options for peer forwarder
| Option | Required | Type | Description |
|---|---|---|---|
| ssl | No | Boolean | Enables TLS/SSL. Default is true. |
| ssl_certificate_file | Conditionally | String | SSL certificate chain file path or AWS S3 path. S3 path example s3://<bucketName>/<path>. Required if ssl is true and use_acm_certificate_for_ssl is false. Defaults to config/default_certificate.pem which is the default certificate file. Read more about how the certificate file is generated here. |
| ssl_key_file | Conditionally | String | SSL key file path or AWS S3 path. S3 path example s3://<bucketName>/<path>. Required if ssl is true and use_acm_certificate_for_ssl is false. Defaults to config/default_private_key.pem which is the default private key file. Read more about how the default private key file is generated here. |
| ssl_insecure_disable_verification | No | Boolean | Disables the verification of server’s TLS certificate chain. Default is false. |
| ssl_fingerprint_verification_only | No | Boolean | Disables the verification of server’s TLS certificate chain and instead verifies only the certificate fingerprint. Default is false. |
| use_acm_certificate_for_ssl | No | Boolean | Enables TLS/SSL using certificate and private key from AWS Certificate Manager (ACM). Default is false. |
| acm_certificate_arn | Conditionally | String | ACM certificate ARN. The ACM certificate takes preference over S3 or a local file system certificate. Required if use_acm_certificate_for_ssl is set to true. |
| acm_private_key_password | No | String | ACM private key password that decrypts the private key. If not provided, Data Prepper generates a random password. |
| acm_certificate_timeout_millis | No | Integer | Timeout in milliseconds for ACM to get certificates. Default is 120000. |
| aws_region | Conditionally | String | AWS region to use ACM, S3 or AWS Cloud Map. Required if use_acm_certificate_for_ssl is set to true or ssl_certificate_file and ssl_key_file is AWS S3 path or discovery_mode is set to aws_cloud_map. |
Authentication options for peer forwarder
| Option | Required | Type | Description |
|---|---|---|---|
| authentication | No | Map | Authentication method to use. Valid options are mutual_tls (use mTLS) or unauthenticated (no authentication). Default is unauthenticated. |
