DynamoDbAction
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()}"
