Connection pooling and bulk heads
- [Narrator] Now a common pattern used with database applications is something called bulkheads and we do that when we need to kind of isolate sets of resources and this is commonly used when we're working with connections, so a common problem, as we've noted, is connection pool exhaustion, and here the idea is that we have a lot of clients or database clients attempting to connect to the database and to make connections, you have access to a data structure called a connection, and oftentimes, those connections are maintained in pools and if we have a single pool of connections, then any client that attempts to access the database has to allocate a connection from that pool.
