Storage and Compute upgrade
06/18/2019 - 0.8.78 - Client-Cloud Update
06/04/2019 - ion-dev 0.9.231
- Improvement: Fixed issue where some older Java libraries could not be loaded in an ion application
05/16/2019 - 477-8741 - Compute Template Update - HTTP Direct
The 477-8741 release contains fixes, enhancements, and dependency updates:
- Enhancement: HTTP Direct integration for ions.
- Enhancement: Improved integration between ions and AWS Network Load Balancers. This eliminates transient errors during rolling deployments.
- Enhancement: Improved integration between ions and AWS Lambda. This also eliminates transient errors.
- Fix: Issue where cluster nodes could become unresponsive when serving multiple databases or a burst of `tx-range` queries.
- Fix: Nested queries could deadlock the query pool on Solo nodes.
- Fix: Increased direct memory on Production nodes to prevent out-of-direct-memory errors.
- Update: Version 1.7.26 of org.slf4j libraries.
05/15/2019 - 0.9.229 - ion-dev && 0.9.34 - ion
- New Feature: HTTP Direct
- Enhancement: Improved integration between ions and AWS NLBs
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 informaton.
The 470-8654 release contains fixes, enhancements, and dependency updates:
- Fix: Production nodes now use the documented -Xss values for starting the JVM, preventing stack overflow when compiling complex ion applications.
- Fix: Fixed bug where ion connections could fail to become aware of recent transactions in a timely manner.
- Fix: Allow bigint values in transaction data.
- Fix: Corrected whitelist handling of function calls from datalog rules.
- Enhancement: New AWS Region - ap-southeast-1.
- Enhancement: Improved valcache cleanup algorithm.
- Enhancement: Reduce storage overhead of transactions.
- Enhancement: Defer creation of VPC Endpoint Service until specifically needed for cross-VPC client access.
- Update to version 2.9.8 of Jackson.
- Update to version 1.11.479 of the AWS SDK for Java.
12/10/2018 - 454-8573 - Compute Template Update
