We have a Reporting platform that heavily depends on aggregation (GROUP BYs) and JOINs.
It’s a single node MySQL instance, and scalability is becoming an issue, so we’re looking for for solutions.
In 3rdEdition of the book “High Performance MySQL”, page 550, it reads:
“NDB is a key-value data store, and it can’t do complex operations such as joins and aggregation”
Is this still true after NDB 7.2 and its performance improvements?
