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

As of 2020-06-10, engine version 1.0.1.2 is being generally deployed. Please note that it takes several days for a new release to become available in every region.

This version is an update of older engine version 1.0.1.0.200457.0.

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:
