Data Types

AWS service descriptions define a number of data types for use in :request maps passed to cognitect.aws.client.api/invoke and responses. aws-api supports them as follows:

AWS type	Clojure/java input type	Clojure/java output type (if different)
structure	map with keyword keys
map	map with arbitrary types for keys
list	sequence
string	string
character	character
boolean	boolean
double	double
float	double
long	long
integer	long
blob	byte[] or java.io.InputStream*	java.io.InputStream
timestamp	java.util.Date

• for the time being, if you submit a java.io.InputStream for a blob, it must fit in memory.

You can validate that your request maps conform to these types by enabling clojure.spec-backed request validation during development:

(cognitect.aws.client.api/validate-requests client true)
