Which strategy prevents data misalignment when using server-side processing with high-frequency updates?

Data Synchronization in Server-Side Mode
When DataTables is configured with serverSide: true, the plugin relies on the draw parameter to synchronize asynchronous AJAX responses. This mechanism ensures that if multiple requests are pending, only the response corresponding to the most recent request is rendered.
In environments where the underlying dataset changes rapidly between page requests, there is a risk that the recordsTotal and recordsFiltered values returned in the JSON response may shift, potentially causing records to be skipped or duplicated across page boundaries during offset-based pagination.
What is the recommended approach to maintain a consistent view for the user without forcing a full table redraw on every update? Does DataTables provide a native way to handle shifting offsets, or must this be managed via a custom server-side cursor?
