MessageAttributeValue¶
Structure Class¶
dataclass
¶
The user-specified message attribute value. For string data types, the value attribute has the same restrictions on the content as the message body. For more information, see Publish.
Name, type, and value must not be empty or null. In addition, the
message body should not be empty or null. All parts of the message
attribute, including name, type, and value, are included in the message
size restriction, which is 256 KiB (262,144 bytes) by default and is
determined by the topic's MaximumMessageSize attribute. For more
