Step 1: Introduction to the Architecture and Components of a Query Optimizer for Distributed Databases:

A query optimizer plays a role in improving the performance of distributed database management systems (DDBMS).

Its main aim is to find a way to execute queries from a range of available options.

When dealing with distributed environments, where data is spread across nodes or sites perfecting query execution becomes more complex.

Let us look at the architecture and components of a query optimizer designed specifically for distributed databases.
