04/25/2019 - 470-8654.1 - Compute, Storage, and Query Group Update
Note Our Cloud Formation templates use node.js lambdas to create support functions for Cloud Formation. April 30th 2019 is the end of life date for AWS Lambda node.js runtime that we currently use.
Effective May 1, 2019, Datomic Cloud CloudFormation templates older than 4/25/2019 will no longer execute. Datomic systems launched with those templates will continue to run, but any template operations (launching or upgrading CloudFormation stacks) will fail.
For more information see the AWS runtime support policy.
- Critical: Updated to Node.js 8.10 runtime. All Datomic Cloud users should upgrade at their earliest convenience.
02/22/2019 - 470-8654 - Compute Template Update
Note If you have created a VPC Endpoint using the provided CloudFormation Template, you will need to delete that CloudFormation Stack prior to upgrading to this version of Datomic Cloud.
Attempting to upgrade to or past this release without deleting the Stack will result in a failed update with the message:
Export <SystemName>-VpcEndpointServiceName cannot be deleted as it is in use by <SystemName>-vpc-endpoint
See the troubleshooting documentation for more information.
