What is Query Plan?

A sequence of steps generated by the query optimizer from the SELECT query. A particular query can often translate to a lot of query plans. The task of query optimizer is to pick a performant query plan among them. Note it's often computational and time prohibitive to permutate all possible query plans and pick the best one. What query optimizer normally does is to strategically choose a subset of query plans and pick the best one among them.
