Suggested Answer:ADE🗳️
E: In connection pooling, after a connection is created, it is placed in the pool and it is used over again so that a new connection does not have to be established. D: Connection pooling often improves application performance, concurrency and scalability. A: Connection pooling also cuts down on the amount of time a user must wait to establish a connection to the database.
D. improved scalability is right. It's used to close old connections and open new ones as needed, so more users can use the same limit of connections just by handling who is needed at the time.
I thought ACE too, I think we are right, from google "Establishing a connection to database is a costly process and has impact to the performance of application. To reduce this connection time to database a pool is maintained so that it can be re-used. " .. If it's expensive, it means that it's expensive on the server, and therefore connection pools is used to reduce server load.
It's expensive in terms of time and resources.With conection pooling you can have the same server load, but with reduced times, better scalability and better performance, so ADE.
By using connection pooling, won't the load on the server be reduced?
