Operations on items
Items in DynamoDB are simply collections of attributes. Attributes can be in the form of
strings, numbers, binaries, or a set of scalar attributes. Each attribute consists of a name and
a value. An item must have a primary key. As we have already seen, a primary key can
have a hash key or a combination of hash and range keys. In addition to the primary key,
items can have any number of attributes except for the fact that item size cannot exceed 64
KB.
While doing various item operations, you should have be aware of following DynamoDB
features.
