How to deal with a large amount of data when pagination in Django?

There are several ways to address the issue of handling large amounts of data in Django pagination.

1. Utilize the pagination feature of the database: when querying data, you can use the pagination feature of the database to limit the amount of data returned, instead of loading all data into memory and then performing pagination. Most databases support pagination query syntax such as LIMIT and OFFSET, which can greatly reduce the system’s memory consumption.
2. Utilizing Django’s built-in Paginator class: Django offers the Paginator class to handle pagination logic, allowing for the pagination display of query results. By using Paginator, it is easy to manage the pagination display of large amounts of data and customize the number of items displayed per page.
3. Using cache: You can store paginated data in cache to reduce the cost of querying and paginating each time. You can utilize Django’s built-in cache system or other third-party cache libraries to implement data caching.
4. Utilize Ajax loading: loading pagination data through Ajax can implement the function of loading more data without refreshing the front-end page, reducing page loading time and server pressure.
5. Utilizing asynchronous task queues: For processing large amounts of data, time-consuming operations can be placed in an asynchronous task queue to reduce blocking time on the main thread, improving system performance and concurrent processing capabilities. Libraries like Celery can be used to implement asynchronous task processing.
