Integration with other AWS components
As we have discussed earlier, we will use AWS CloudSearch to give search functionality to
the user. We can create a domain for the same as we have learned in Chapter 6 , Integrating
DynamoDB with Other AWS Components . We can use auto index generation options
provided by the AWS CloudSearch console to get seamless integration. As seen earlier, for
already existing data in DynamoDB, we can use the CloudSearch console tool to upload
the data, and for each new entry, you can write a CloudSearch API call to upload the topic
data in SDF format to CloudSearch.
You can also integrate a query API from CloudSearch to help users search in the topic data-
base. For more details, check out the CloudSearch API documentation at ht-
tp://aws.amazon.com/documentation/cloudsearch/ .
In the architecture diagram, we have also shown that we can use AWS EMR to process
batch jobs to get more information about the data stored. We can go ahead and implement a
rating/review system for the topics and authors and can also implement a recommendation
engine that recommends topics to users as per their likes.
