we have requirement to have grouping feature in UI so we used pyTableToolbar Section. but after implementation we are facing slowness and hitting the performance a lot after we apply grouping as we have lots of records. So do we have any other alternate to achieve this without performance issue and Could help me with what is the limitation that while using grouping feature in pega like what is maximum number of records we can fetch and apply group operations without affecting performance and maximum number of columns we can have in table layout section for grouping feature.
