Database Reference
In-Depth Information
The
Scan
radio button will not allow us to specify the condition for retrieving items, but
Query
will allow us to do that. Clicking on the
Go
button after selecting the
Query
radio
button will show all the indexes for the selected table. Selecting the index from the drop-
down will automatically update the
Hash Key
and
Range Key
dropdowns (as shown in
the following screenshots). The first index is the primary index and the rest are secondary.
There are only two
Hash Key
attributes (
BookTitle
and
Publisher
) involved in the three
indexes.
