Values_0.DynamoDBActionSourceDescribes 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()}"
type nonrec t = {tableName : TableName.t;The name of the DynamoDB table.
*)roleArn : AwsArn.t;The ARN of the IAM role that grants access to the DynamoDB table.
*)operation : DynamoOperation.t option;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.
*)hashKeyField : HashKeyField.t;The hash key name.
*)hashKeyValue : HashKeyValue.t;The hash key value.
*)hashKeyType : DynamoKeyType.t option;The hash key type. Valid values are "STRING" or "NUMBER"
*)rangeKeyField : RangeKeyField.t option;The range key name.
*)rangeKeyValue : RangeKeyValue.t option;The range key value.
*)rangeKeyType : DynamoKeyType.t option;The range key type. Valid values are "STRING" or "NUMBER"
*)payloadField : PayloadField.t option;The action payload. This name can be customized.
