Can somebody explain what does connection pooling mean by simple samples? i want to learn it in simpler terms, google search gives results which makes me more confused.
Pooling means using some cache entries for the purpose of reusing. In particular for the connection pooling, it stores the connection (eg: database connection) in a 'pool' which is cached. With that case, we can reuse the same connection later without reconnecting.
Creating or opening the connection for each request is a costliest operation.Costliest in means of consuming the time for every request is a serious problem.to overcome this creating the set of connections(pool of connections) at server startup time and make them availble to the application is a good solution
