Get an introduction to connection pooling and management.
- [Instructor] The concept of Connection Pooling…is something that you'll run into when you're running…systems that actually receive multiple connections…at a given time and then connect to the database…across multiple threads.…This is very, very common, for instance,…in Java web applications where you have…a single web application that may have multiple…connections to the database as well as multiple…users connecting to it at the same time.…So connection pooling is a very common data access…pattern that allows you to reuse connections…from request to request.…
Now this sort of works as a cache, so you have a pool…or a cache of connections and each time you need…a connection, you go to the cache to get it instead…of creating it yourself and connecting to the database.…Now often this is managed by a pooling framework…so you don't write the cache itself,…you just reach out to the pooling framework…and say hey, I need a connection, give me one…and it will create one behind the scenes…if you don't have one.…
Now developers do often configure connection pooling…
