Hi!
Small proposal for reducing the amount of
COUNT
queries when the result set is full already. Kinda hits performance.Currently, the paginator makes
COUNT
query for each request (unless the:count
option 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]
, theCOUNT
queries 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).
