Amazon Neptune Engine Version (2020-04-02)

As of 2020-04-02, engine version is being generally deployed. Please note that it takes several days for a new release to become available in every region.

Improvements in This Engine Release

  • You can now queue up to 64 bulk-load jobs, rather than having to wait for one to finish before initiating the next one. You can also make execution of a queued load request contingent on the successful completion of one or more previously queued load jobs using the dependencies parameter of the load command. See Neptune Loader Command.

  • Full-text-search output can now be sorted (see Full-text search parameters).

  • There is now a DB cluster parameter for invoking Neptune streams, and the feature has been moved out of Lab Mode. See Enabling Neptune Streams.

Defects Fixed in This Engine Release

  • Fixed a stochastic failure in server startup which delayed instance creation.

  • Fixed an optimizer issue where BIND statements in the query made the optimizer start out with unselective patterns in join-order planning.

Query-Language Versions Supported in This Release

Before upgrading a DB cluster to version, make sure that your project is compatible with these query-language versions:

  • Gremlin version: 3.4.3

  • SPARQL version: 1.1

Upgrade Paths to Engine Release

Your cluster will be upgraded to this patch release automatically during your next maintenance window if you are running engine version

You can manually upgrade any previous Neptune engine release to this release.

Upgrading to This Release

Amazon Neptune is now generally available.

If a DB cluster is running an engine version from which there is an upgrade path to this release, it is eligible to be upgraded now. You can upgrade any eligible cluster using the DB cluster operations on the console or by using the SDK. The following CLI command will upgrade an eligible cluster immediately:

For Linux, OS X, or Unix:

aws neptune modify-db-cluster \ --db-cluster-identifier (your-neptune-cluster) \ --engine-version \ --apply-immediately

For Windows:

aws neptune modify-db-cluster ^ --db-cluster-identifier (your-neptune-cluster) ^ --engine-version ^ --apply-immediately

Updates are applied to all instances in a DB cluster simultaneously. An update requires a database restart on those instances, so you will experience downtime ranging from 20–30 seconds to several minutes, after which you can resume using the DB cluster.

For more information about upgrading your engine version, see Neptune engine updates. If you have any questions or concerns, the Amazon Support team is available on the community forums and through Amazon Premium Support.
