I'm using the documentClient
to work with dynamodb
.
I have an array of the primary keys.
What method should I use, Scan
or Query
to get items?
If you have a list of primary key values, you should use the BatchGetItem
API. Query
does not really help you are, and a Scan
is unneeded because you already know the primary keys to index into.
The
BatchGetItem
operation returns the attributes of one or more items from one or more tables. You identify requested items by primary key.
