For some of our API requirements, we used Global Secondary Indexes (GSIs) as we need to query the data using a different attribute than the (transaction) Id. GSIs are sparse by default, meaning if the defined partition and sort keys for the GSI do not exist on the item, the item will not be written to the GSI. Sparse indexes are useful if we want to query only a subsection of the data from the table. In the example above, the attribute marketplace is only available for the account items. Creating a GSI with ‘amzChannel’ as the primary key and marketplace as the sort key allows us to quickly query every accounts belonging to a particular amzChannel and marketplace without querying transactional invoice items.
