This release is mainly for scalability improvements, with some functionality stabilization and build/test toolchain improvements.

Scalability scale-out architecture:

  • Introduce the new scale-out architecture in addition to the existing scale-up design. The new architecture supports multiple partitions, with each partition supporting the existing scale-up configuration.
  • Initial implementation of the scale-out architecture that:
    • Supports multiple tenant partitions and a single resource manager. Multiple resource manager will be supported in subsequent releases.
    • Passes 20K density scalability test with 2 tenant partitions and 1 resource manager.

Performance improvements ported from Kubernetes 1.18:

  • API Server cache index improvement
  • List and watch performance improvement
  • Fix watcher memory leak upon closing
  • Object serialization improvement
  • Reduce node status update frequency and pod patch update frequency

Upgrade to build/runtime golang 1.13 version

Test Improvements:

  • Make density test cases tenancy-aware
  • Improve scalability test suite for optimized configurations and better logging and tracing

Critical bug fixes:

  • Fix bugs about PV/PVC for multi-tenancy (#937)
  • Fix concurrent map write issue at AggregateWatcher stop (#825)
  • Fix memory leak in AggregatedWatcher (#787)
