http_source

http_source is a source plugin that supports HTTP. Currently, http_source only supports the JSON UTF-8 codec for incoming requests, such as [{"key1": "value1"}, {"key2": "value2"}]. The following table describes options you can use to configure the http_source source.

Option	Required	Type	Description
port	No	Integer	The port that the source is running on. Default value is `2021`. Valid options are between `0` and `65535`.
health_check_service	No	Boolean	Enables the health check service on the `/health` endpoint on the defined port. Default value is `false`.
unauthenticated_health_check	No	Boolean	Determines whether or not authentication is required on the health check endpoint. Data Prepper ignores this option if no authentication is defined. Default value is `false`.
request_timeout	No	Integer	The request timeout, in milliseconds. Default value is `10000`.
thread_count	No	Integer	The number of threads to keep in the ScheduledThreadPool. Default value is `200`.
max_connection_count	No	Integer	The maximum allowed number of open connections. Default value is `500`.
max_pending_requests	No	Integer	The maximum allowed number of tasks in the `ScheduledThreadPool` work queue. Default value is `1024`.
authentication	No	Object	An authentication configuration. By default, this creates an unauthenticated server for the pipeline. This uses pluggable authentication for HTTPS. To use basic authentication define the `http_basic` plugin with a `username` and `password`. To provide customer authentication, use or create a plugin that implements ArmeriaHttpAuthenticationProvider.
ssl	No	Boolean	Enables TLS/SSL. Default value is false.
ssl_certificate_file	Conditionally	String	SSL certificate chain file path or Amazon Simple Storage Service (Amazon S3) path. Amazon S3 path example `s3://<bucketName>/<path>`. Required if `ssl` is set to true and `use_acm_certificate_for_ssl` is set to false.
ssl_key_file	Conditionally	String	SSL key file path or Amazon S3 path. Amazon S3 path example `s3://<bucketName>/<path>`. Required if `ssl` is set to true and `use_acm_certificate_for_ssl` is set to false.
use_acm_certificate_for_ssl	No	Boolean	Enables a TLS/SSL using certificate and private key from AWS Certificate Manager (ACM). Default value is false.
acm_certificate_arn	Conditionally	String	The ACM certificate Amazon Resource Name (ARN). The ACM certificate takes preference over Amazon 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, that ACM takes to get certificates. Default value is 120000.
aws_region	Conditionally	String	AWS region used by ACM or Amazon S3. Required if `use_acm_certificate_for_ssl` is set to true or `ssl_certificate_file` and `ssl_key_file` is the Amazon S3 path.
