The interval for each retry is a random value between 10 and 20 seconds. EXPONENTIAL_DECAY_RETRY: Exponential decay retry. Retries up to 176 times. The interval for each retry increases exponentially to 512 seconds. The total retry time is 1 day. The specific interval for each retry is: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 512, ..., 512 seconds (a total of 167 retries at 512 seconds).

ParamList	List<Param>	Yes		The parameters passed by the event.
resourceKey	String	Yes	body	The parameter of the destination service.
form	String	Yes	TEMPLATE	The format for event transformation. Four types are available: ORIGINAL: Complete event. You do not need to define value and template. EventBridge routes the complete structure of the original CloudEvents event to the event target without transformation. For more information, see Complete event. JSONPATH: Partial event. You do not need to define template. You only need to define value. EventBridge extracts parameters from the CloudEvents event using JSONPath and routes the specified event content to the event target. For more information, see Partial event. The following is a sample value. `$.data.name` CONSTANT: Constant. You do not need to define template. You only need to define value. Regardless of the event content, EventBridge routes only the constant defined in value to the event target. For more information, see Constant. The following is a sample value. `"test1"` TEMPLATE: Template. You must define value and template. EventBridge extracts parameters from the CloudEvents event using JSONPath, stores the parameter values in value, and then routes them to the event target in the format defined by template. For more information, see Template. The following is a sample value. `{ "name":"$.data.name", "constant":"Please deal with it timely." }` The following is a sample template. `The instance is broken, which name is ${name}, ${constant}`
value	String	Yes	`{\"key\"=\"value\"}`	The value of the transformed event.

Simple Log Service

If you select Simple Log Service (SLS) as the event target, the value of the Type parameter in the metadata is acs.sls and the Endpoint parameter is the configured URL in the acs:sls:${regionId}:${accountId}:project/${project}/logstore/${logstore} format. The following table describes the resourceKey field in the ParamList parameter.

resourceKey	Required	form	value	template
Project	Yes	CONSTANT	The name of the log project.	None
LogStore	Yes	CONSTANT	The name of the Logstore.	None
Topic	No	CONSTANT TEMPLATE JSONPATH	The log topic.	The format for event transformation. Four types are available: ORIGINAL: Complete event. You do not need to define value and template. EventBridge routes the complete structure of the original CloudEvents event to the event target without transformation. For more information, see Complete event. JSONPATH: Partial event. You do not need to define template. You only need to define value. EventBridge extracts parameters from the CloudEvents event using JSONPath and routes the specified event content to the event target. For more information, see Partial event. The following is a sample value. `$.data.name` CONSTANT: Constant. You do not need to define template. You only need to define value. Regardless of the event content, EventBridge routes only the constant defined in value to the event target. For more information, see Constant. The following is a sample value. `"test1"` TEMPLATE: Template. You must define value and template. EventBridge extracts parameters from the CloudEvents event using JSONPath, stores the parameter values in value, and then routes them to the event target in the format defined by template. For more information, see Template. The following is a sample value. `{ "name":"$.data.name", "constant":"Please deal with it timely." }` The following is a sample template. `The instance is broken, which name is ${name}, ${constant}`
Body	No	CONSTANT ORIGINAL JSONPATH TEMPLATE	The log content.	See the template for Topic.
ContentType	Yes	CONSTANT	The content type.	Valid values: JSON and KeyValue. Default value: JSON. If you select JSON, the index field of the log delivered to SLS is `content`, and its value is the event content defined in the Body parameter. If you select KeyValue, the index field and value of the log delivered to SLS are determined by the structure defined by ContentSchema.
RoleName	Yes	CONSTANT	The role configuration.	None
ContentSchema	No	CONSTANT	A custom content template for the indexes and values of logs that are written to SLS.	`{ "Key_1":{ "form":"CONSTANT", "value":"myKey01" }, "Value_1":{ "form":"JSONPATH", "value":"$.data.myValue01" } }` The field names "Key_1" and "Value_1" represent an index-value pair.

The following is a JSONPath example:

{
    "id":"MwOpn5yyemTlQjE5JwYjme****",
    "type":"acs.sls",

If you select CloudFlow as the event target, the value of the Type parameter in the metadata is acs.fnf and the Endpoint parameter is in the acs:fnf:${region}:${AccountId}:flow/${flow} format. The following table describes the resourceKey field in the ParamList parameter.

resourceKey	Required	form	value	template
FlowName	Yes	CONSTANT	The flow name.	None
ExecutionName	No	JSONPATH CONSTANT TEMPLATE	The execution name.	The format for event transformation. Four types are available: ORIGINAL: Complete event. You do not need to define value and template. EventBridge routes the complete structure of the original CloudEvents event to the event target without transformation. For more information, see Complete event. JSONPATH: Partial event. You do not need to define template. You only need to define value. EventBridge extracts parameters from the CloudEvents event using JSONPath and routes the specified event content to the event target. For more information, see Partial event. The following is a sample value. `$.data.name` CONSTANT: Constant. You do not need to define template. You only need to define value. Regardless of the event content, EventBridge routes only the constant defined in value to the event target. For more information, see Constant. The following is a sample value. `"test1"` TEMPLATE: Template. You must define value and template. EventBridge extracts parameters from the CloudEvents event using JSONPath, stores the parameter values in value, and then routes them to the event target in the format defined by template. For more information, see Template. The following is a sample value. `{ "name":"$.data.name", "constant":"Please deal with it timely." }` An example value for template is as follows. `The instance is broken, which name is ${name}, ${constant}`
