Summary

This pre-release is optional for users and operators to upgrade.

Notable changes

  • Performance improvement: Zero serialization of chunks after being encoded in the dispersal flow, eliminating 20s to minutes overhead on dispersal latency
  • Performance observability: Added metrics for blob age, blob encoding latency and system throughput
  • Robustness fixes:
    • Added blob state transition invariant checking to make sure blob state changes are correct
    • Added blob state recovery for handling failed blobs stuck in DISPERSING state
