reliability of asset moves and scales</li> <li>Updating the placement or replication factor midway through an existing scale/move operation, cancelling an in-flight scale/move, or peer-removing is now much safer</li> <li>ADR: <a

and any consumers on those streams, from a node</li> <li>The new <code>$JS.API.STREAM.PEER.EVACUATE.*</code> endpoint can safely evacuate a peer, and any consumers on that peer, from a stream</li> <li>These operations combined allow for maintenance operations with full transfer of data and state without having to peer-remove first</li> <li>ADR: <a

lower the quorum-needed for the metalayer, in order to facilitate the recovery of a system where nodes have been permanently lost and the metalayer cannot reach quorum</li> <li>ADR: <a

snapshots which reads out per-message rather than per-block</li> <li>The new backup format also now correctly includes non-replicated consumers on follower nodes</li> <li>ADR: <a

source stream recreation (<a href="https://redirect.github.com/nats-io/nats-server/issues/8384";>#8384</a>) <ul> <li>The server now detects a source stream being recreated, restarting the sourcing back from the beginning, ensuring new messages are sourced</li> </ul> </li> <li>Stream source indexing (<a href="https://redirect.github.com/nats-io/nats-server/issues/8282";>#8282</a>, <a

previously required expensive backward scans through the stream to find the last sourced indices. These are now persisted in an index for instant lookup.</li> </ul> </li> <li>Domain-prefixed JS API in system account (<a href="https://redirect.github.com/nats-io/nats-server/issues/8429";>#8429</a>) <ul> <li>When a system account is bridged between the hub and a leaf node, the domain-prefixed JS API can now be used to operate on the leaf node while directly connected to the hub</li> </ul> </li> </ul> <h3>Changed</h3> <p>JetStream</p> <ul> <li>Streams now have a default limit of 1000 consumers, unless <code>max_consumers</code> is specified in the stream config or account limits (<a href="https://redirect.github.com/nats-io/nats-server/issues/8337";>#8337</a>, <a href="https://redirect.github.com/nats-io/nats-server/issues/8566";>#8566</a>) <ul> <li>Applications planning to use a large number of consumers on a stream should configure <code>max_consumers</code> in the stream config or account limits to an appropriately high number</li> <li>The server-wide default of 1000 can be overridden by setting <code>default_max_consumers</code> in the JetStream limits, or can be disabled by setting to <code>-1</code></li> <li>This limit does not affect existing consumers and will not result in consumer deletions, only the creation of new consumers is prevented</li> </ul> </li> <li>Sync changes for replicated streams (<a href="https://redirect.github.com/nats-io/nats-server/issues/8447";>#8447</a>) <ul> <li>When the <code>sync_interval</code> is set to <code>always</code>, replicated streams now sync their WAL entries but no longer sync upper stream layer writes</li> <li>The synced log allows the stream to recover safely, but removing unnecessary syncs from the upper stream layer dramatically improves performance</li> </ul> </li> </ul> <!-- raw HTML omitted --> </blockquote> <p>...
