Struct rusoto_iot::DynamoDBAction
[−]
[src]
pub struct DynamoDBAction { pub hash_key_field: String, pub hash_key_type: Option<String>, pub hash_key_value: String, pub operation: Option<String>, pub payload_field: Option<String>, pub range_key_field: Option<String>, pub range_key_type: Option<String>, pub range_key_value: Option<String>, pub role_arn: String, pub table_name: String, }
Describes an action to write to a DynamoDB table.
The tableName
, hashKeyField
, and rangeKeyField
values must match the values used when you created the table.
The hashKeyValue
and rangeKeyvalue
fields use a substitution template syntax. These templates provide data at runtime. The syntax is as follows: ${sql-expression}.
You can specify any valid expression in a WHERE or SELECT clause, including JSON properties, comparisons, calculations, and functions. For example, the following field uses the third level of the topic:
"hashKeyValue": "${topic(3)}"
The following field uses the timestamp:
"rangeKeyValue": "${timestamp()}"
Fields
hash_key_field: String
The hash key name.
hash_key_type: Option<String>
The hash key type. Valid values are "STRING" or "NUMBER"
hash_key_value: String
The hash key value.
operation: Option<String>
The type of operation to be performed. This follows the substitution template, so it can be ${operation}
, but the substitution must result in one of the following: INSERT
, UPDATE
, or DELETE
.
payload_field: Option<String>
The action payload. This name can be customized.
range_key_field: Option<String>
The range key name.
range_key_type: Option<String>
The range key type. Valid values are "STRING" or "NUMBER"
range_key_value: Option<String>
The range key value.
role_arn: String
The ARN of the IAM role that grants access to the DynamoDB table.
table_name: String
The name of the DynamoDB table.
