What is the best way to implement paging and r

Answer 1

There's literature about it:

• Optimized Pagination using MySQL, making the difference between counting the total amount of rows, and pagination.

• Efficient Pagination Using MySQL, by Yahoo Inc. in the Percona Performance Conference 2009. The Percona MySQL team provides it also as a Youtube video: Efficient Pagination Using MySQL (video),

The main problem happens with the usage of large OFFSETs. They avoid using OFFSET with a variety of techniques, ranging from id range selections in the WHERE clause, to some kind of caching or pre-computing pages.

There are suggested solutions at Use the INDEX, Luke:

• "Paging Through Results".

• "Pagination done the right way".
