Amazon Neptune Engine Updates 2019-09-19

IMPORTANT: THIS ENGINE VERSION IS NOW DEPRECATED

No new instances using this engine version will be created, beginning 2021-04-27.

Version: 1.0.1.0.200457.0

Amazon Neptune 1.0.1.0.200457.0 is generally available. All new Neptune DB clusters, including those restored from snapshots, will be created in Neptune 1.0.1.0.200457.0 after the engine update is complete for that Region.

Existing clusters can be upgraded to this release immediately using the DB cluster operations on the console or by using the SDK. You can use the following CLI command to upgrade a DB cluster:

aws neptune apply-pending-maintenance-action \ --apply-action system-update \ --opt-in-type immediate \ --resource-identifier arn:aws-cn:rds:<region>:<account number>:<resourcetype>:<name>

Updates are applied to all instances in a DB cluster simultaneously. An update requires a database restart on all instances in a DB cluster, so you will experience downtime ranging from 20–30 seconds to several minutes, after which you can resume using your DB cluster or clusters. You can view or change your maintenance window settings on the Neptune console.

If you have any questions or concerns, the Amazon Support team is available on the community forums and through Amazon Premium Support.

Defects Fixed in This Engine Release

  • Fixed a Gremlin correctness issue introduced in the previous engine release (1.0.1.0.200369.0) by removing the performance improvement to conjunctive predicate handling that caused it.

  • Fixed a SPARQL bug that caused queries with DISTINCT and a single pattern wrapped into OPTIONAL to generate an InternalServerError.
