Expand description
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 (Non-exhaustive)

syntax; cannot be matched against without a wildcard ..
; and struct update syntax will not work.table_name: Option<String>
The name of the DynamoDB table.
role_arn: Option<String>
The ARN of the IAM role that grants access to the DynamoDB table.
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
.
hash_key_field: Option<String>
The hash key name.
hash_key_value: Option<String>
The hash key value.
hash_key_type: Option<DynamoKeyType>
The hash key type. Valid values are "STRING" or "NUMBER"
range_key_field: Option<String>
The range key name.
range_key_value: Option<String>
The range key value.
range_key_type: Option<DynamoKeyType>
The range key type. Valid values are "STRING" or "NUMBER"
payload_field: Option<String>
The action payload. This name can be customized.
