v0.5.7-rc2
Pre-release
Pre-release
Issues Addressed
- Existing computations may starve initialization of new computations. See #1637
- Duchy mill writing output blob error should be transient. See #1644
- Avoid failing Measurements at Duchy due to stale ComputationParticipant state. See #1663
- Fix batch get metrics limit in reports service. See #1529
Highlights
- Mill horizontal autoscaling. See #1697
- This significantly reduces cost during low traffic periods.
- More performance improvements for Report creation. See #1641
- Improved Duchy fault tolerance.
- The HMSS EDP client library is published as a Maven artifact See #1710
Potentially Requiring Action
- As part of the Mill horizontal autoscaling feature, the K8s Deployment objects for Mills are replaced with PodTemplate objects.
- The PodTemplates are used by new MillJobScheduler Deployment to schedule Mill Jobs.
- The MillJobScheduler Deployment needs some permissions on K8s resources in the same cluster using K8s RBAC. For the
dev
configuration, this consists of a new Role and RoleBinding.
- Kubernetes object configuration changes for HMSS. Some of these are required even if HMSS is not enabled. See the updated deployment guides for GKE and EKS.
- There is a new HMSS Mill.
- The Kingdom internal API and public API servers have a new required
--hmss-protocol-config-config
option. In thedev
configuration, this comes from thehmss_protocol_config_config.textproto
file in thecerts-and-configs
Secret. - The Herald now needs access to blob storage. This means it needs to run under a K8s ServiceAccount that has access to the appropriate bucket, as well as the appropriate command line options.
- The Herald and the HMSS Mill have a new
--key-encryption-key-file
option for worker (non-aggregator) Duchies. In thedev
configuration, this comes from thecerts-and-configs
Secret. - The Duchy Requisition fulfillment server may need more heap space to handle HMSS Requisitions.
- The EDP simulator may need more heap space to fulfill HMSS Requisitions.
