This article mainly introduces "what are the advantages and disadvantages of ADO.NET connection pool". In daily operation, I believe many people have doubts about the advantages and disadvantages of ADO.NET connection pool. The editor consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful to answer the doubts about "what are the advantages and disadvantages of ADO.NET connection pool?" Next, please follow the editor to study!

ADO.NET connection pooling has been developed for a long time, and many users are familiar with ADO.NET connection pooling. Here I would like to make a point about ADO.NET connection pooling. Connection pooling allows an application to obtain a connection from a connection pool and use that connection without having to establish a new connection for each connection request. Once a new connection is created and placed in the connection pool, the application can reuse the connection without having to implement the entire database connection creation process.

When an application requests a connection, the connection pool allocates a connection to the application instead of re-establishing a connection; when the application finishes using the connection, the connection is returned to the connection pool rather than released directly.

How to implement connection pooling

Make sure you use the same connection string each time (the same as the connection pool); the connection pool works only if the connection string is the same. If the connection string is different, the application does not use the connection pool but creates a new connection.

Analysis of the advantages of ADO.NET connection Pool View

The main advantage of using connection pooling is performance. The time it takes to create a new database connection depends largely on the speed of the network and the distance between the application and the database server, and this process is usually a time-consuming process. After using the database connection pool, the database connection request can be satisfied directly through the connection pool without the need to reconnect and authenticate to the database server for the request, which saves time.

Analysis of the shortcomings of ADO.NET connection Pool View

There may be multiple unused connections to the database in the database connection pool (which means a waste of resources).

Tips and tips

1. Create a connection pool when you need a database connection, not in advance. Close the connection as soon as you finish using it, and don't wait for the garbage collector to deal with it.

two。 Ensure that all user-defined transactions are closed before closing the database connection.

3. Do not close all connections in the database and ensure that at least one connection is available in the connection pool. If memory and other resources are your first consideration, you can close all connections and create a connection pool when the next request arrives.

At this point, the study on "what are the advantages and disadvantages of ADO.NET connection pooling" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
