hello, I have a project that uses a datagrid to handle millions of data, and the datasource I use is an array-converted from JSON APIs from our backend, if I use an array, the memory exhausted error message always appears. I've seen and tried examples of handling big data using serverside and fastrender with datasources directly from PDO, but we don't think it's suitable. the question is how to handle a large array of data sources when using a datagrid without sacrificing a lot of memory? is there a way for asynchronously processing or some kind of lazyload?
