Summary
In this chapter, we learned important NoSQL and HBase design principles, that is,
consistent denormalization and creation of new (index) tables any time we were
presented with an additional query. That's the rule—define the queries first and then
design the tables to answer these queries efficiently. If you can't answer a query with
the current table structure, you might be faced with a dilemma of having queries that
will run quite slow or have the additional burden of maintaining index tables.
In the next chapter, we will conclude our journey of the advanced NoSQL design
principles, that is, many-to-many relationships, time-related events (not to be
confused with time series data), and dealing with transactions in NoSQL (where
I need to remind you that transactions are not provided).
