Query Optimization using PostgreSQL Profiler смотреть онлайн

In this video, we will see how the PostgreSQL Query Profiler works. It's a functionality built into dbForge Studio for PostgreSQL that helps DBAs and developers troubleshoot slow-running queries to optimize performance.

The Query Profiler has a graphical interface that shows each step of a Postgres query’s execution plan.

The Query Profiling information includes:
? The date and time of the query
? The total execution time and planning time
? A plan tree
? A graphical plan diagram
? The top operations within the query plan, and
? An XML version of the query plan

As we will see, the plan diagram has an extensive set of information that helps you identify potential bottlenecks.
