Amazon Neptune Engine Version 1.0.1.2 (2020-06-10)

IMPORTANT: THIS ENGINE VERSION IS NOW DEPRECATED

Starting from 2021-04-27, no new instances using this engine version will be created.

Improvements in This Engine Release

• Neptune now raises an IllegalArgumentException if you try to access a non-existent property, vertex, or edge. Previously, Neptune raised an UnsupportedOperationException in that situation.

  For example, if you try to add an edge referencing a nonexistent vertex, you will now raise an IllegalArgumentException.

Defects Fixed in This Engine Release

• Fixed a bug where dictionary and user transaction commits were out of order when two value->id mappings were being inserted concurrently.

• Fixed a bug in load-status serialization.

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

• Fixed a cursor leak.

Before upgrading a DB cluster to version 1.0.1.2, make sure that your project is compatible with these query-language versions:

• Gremlin version: 3.4.1
