Question: Is DynamoDB good for analytics?
Answered by Rafal Wilinski
Answer
It is true that because you cannot run arbitrary queries against DynamoDB tables (technically speaking you can but it's extremely inefficient due to Scan nature), you cannot perform ad-hoc reports of your data. That might be disappointing. However, there are solutions to that:
- You can stream your data from DynamoDB to Redshift or some other relational database built for reporting and analytics purposes
- You can build aggregation functions on your own. These functions plugged to the DynamoDB Streams will be automatically recalculating your composite statistics or rollups providing always the most up-to-date state of some aggregate.
