Patches and point releases for the Neo4j database are automatically applied to Neo4j Aura deployments when they become available.
While we cannot promise when a particular patch will be applied, we will make every effort to perform patching operations non-disruptively.
Old cluster members (the server addresses you see in sysinfo) will be replaced by new ones, one by one.
As a result, the routing table held by the driver will have to be updated to accommodate the new members.
This will happen automatically upon a new connection request or retry on failure of an existing connection.
Please note any active connection(connection performing a transaction) will be preserved during such restarts.
Due to how the Neo4j Aura clusters are managed, you should experience no downtime due to patching operations as long as you are using transaction functions.
