I have been looking around for implementing pagination. Most of the literature point out to getting the whole records from the Database into the memory and display pagination. However I am looking at 2 level pagination, one at UI level and other at getting fix set of records from Database.
For example, I might want to show to the user only 10 records per page but would like to retrieve say about 100 records only from the database, even if the select query matches more that , say, 300 records. Getting all the 300 records at one go will be costly. So I was thinking of having another level of pagination where a parameter will specify how many records to be retrieved from the database.
I would be grateful for any help or pointers for best practices surrounding such requirement.
