The Confluent Schema Registry provides several compatibility modes to enforce these rules when updating schemas.</p> </div> <div class="paragraph"> <p>There are two key directions of compatibility:</p> </div> <div class="ulist"> <ul> <li> <p><strong>Backward Compatibility (Upward Compatibility)</strong>: Old consumers can read data produced with a newer schema.</p> </li> <li> <p><strong>Forward Compatibility (Downward Compatibility)</strong>: New consumers can read data produced with an older schema.</p> </li> </ul> </div>
