Hi!
Small proposal for reducing the amount of
COUNTqueries when the result set is full already. Kinda hits performance.Currently, the paginator makes
COUNTquery for each request (unless the:countoption provided by user).On some big tables (millions records) with many filters it adds a lot to response time, as while the main result is limited by user defined limit params, like
page[:size], theCOUNTqueries are executed against the whole table.And it tends to be redundant if the amount of records returned for a query is already less than limit specified (as there won't be any more pages).
