DynamoDB provides the ability to supply additional attributes, a local secondary index and a global secondary index. These additional attributes consumed by the DynamoDB AWS Provider as maps/lists.
In addtion to the consumption as maps/lists there are additional requirements that the range/hash keys be added to the additional attributes if declared. They are not added if undeclared.
The module will use a null_resource to manage the secondary indexes. Creating
them from the existences of appropriate maps/lists.
Properties related to these resources will consume a list of maps as input. These will them be mapped to the appropriate resource within in the module.
The range/hash key will be added automatically to the additional attributes by the module, reducing the load on the consumer with implementation detail.
This provides a huge amount of flexibility for the module. Enabling secondary indexes to be fully configured by consumers and additional attributes to be added. In addition the consumer does not have to add the range/hash keys to attributes as this is done automatically.
