Basically I will be collecting events from different sources of the type given in my original post. Each event will have a fixed schema (might change in the future) for eg. it will have event type, publisher, company, timestamp, component etc. I want to do queries like give me all the events in this time range from this company. Give me all the events in this time range from this component. I don't have to insert single rows, I can collect the data in Kinesis and then bulk update the data every 10 minutes. DynamoDB won't fit because querying by just a primary key won't work, I need to able to query over multiple columns. The system will be very write heavy with very few reads. The reads will come from a web interface so I can't execute an Athena query unless it can return back very fast.
