title: How to keep two tables in sync
body: <p>I want to keep a table in sync between various clients and I'm almost sure that this is a thing but I don't know the name of the service I need.</p>
  <p>User A and user B are visiting the same web page and the page shows a table with data queried from a DB.</p>
  <p>User B inserts a new record or updates a record.</p>
  <p><strong>Is there a way for me to update the table for user A without the need for user A to manually refresh?</strong> I can use pub/sub but it's some work and I was wondering if there is a simpler way...</p>
  <p><strong>Merci!</strong></p>
