how to filter-rows dynamiclly and high effiently

[Nyx2022]

hello,i'm using this lib and like it more and more.
but i have a scene:
i will pass rows data from backend to frontend frequently,the data will more and more in frontend,so i provide some filters for user to show what they need,and i will do not control the data from backend,because user will change their filters in any time.
so ,when some new data from back,will call concat method to add into grid data,like:data = data_new.concat(data),then i will call "filter-rows" to determine which can show,which can not show,so you can get one conclusion:the old data will be calculated every time,it is very bad and low-effient,if the data from back is very frequently,it even worse:some rows will still show even if it should be hidden

so i wish get help from any experienced one
thank you in advance

Hello,

I see your pattern and understand your concerns. This is how you can improve it:

• (not so good) if data comes in small portions, than instead of recreating data, add new rows by executing the "add-row" action. In this case DataGrid will not have to process all the data to determine rendering bounds. Still, you have to filter the data afterwards, as by design we do not refilter grid data automatically when data changes. And even if we did this, the same performance issue would arise, but you would have less control of it
• (better, but less with the DataGrid) - do not filter data inside the grid, but filter you data array before parsing it to DataGrid. What it gives you: you can run your filtering function against new data only and then append or call "add-row" only for the data that should be visible

In the latter case you can create visual filters outside the DataGrid as separate input controls or you can still make use of header filters: set filterValues prop to define visible filter values (this alone does not trigger filtering) and, when users type, intercept the "filter-rows" action to filter the data array outside the DataGrid.
