Summary
Optimize the performance of Discover when showing the default document view. So far we returned a new reference of
['_source']in every render, which made e.g. toggling checkboxes in this case really slow (~500ms), because data grid thought it got completely new columns. Keeping the reference around improves that significantly and toggling checkboxes in the default document view, is now not feeling laggy anymore.To test: Compare performance of toggling checkboxes in a new discover search using data grid (without any columns, just the "Document") before and with this change.
