This might be a public service listing records of public companies. This tutorial uses the use code of listing a number of companies. However, because of the lower memory usage, this solution is also more scalable and that is typically a more important consideration when it comes to web applications. This means that a new query will be run each time the user moves between pages so there is a performance overhead with this approach. This is easy to implement but does not scale well as it could potentially use a lot of memory on the server, limiting the number of users that can be supported at any time.Īn alternative approach is to implement pagination in the data services layer so that only a single page of information is loaded from the database at any time. One simple aproach is simply to run the query against the database and store all of the results in memory in the user's session and have the view render a subset of those results. There are some different approaches to implementing pagination. Typically, web applications return the data one page at a time and allow the user to navigate between those pages. When users of web applications request data, such as a list of bank transactions, it is usually not a good idea to return all of that data in a single page as there could be hundreds or thousands of records. This short tutorial provides sample code for implementating pagination with the Spring Framework.
