What's New

RPC error handling improves; cluster adds metrics and span naming changes

Breaking Changes

  • Drop the entity id from server-side entity RPC span names to keep span name cardinality bounded.

New Features

  • Add ClusterMetrics.shardReleaseDuration timer to track runner release times.
  • Deliver client interrupts to draining entities during shard handoff.
  • Keep the effect_cluster_shards gauge accurate when shards are released or locks are lost.

Improvements

  • Handle interrupts and acknowledgements after RPC EOF.
  • Fail in-flight RPC requests on a missed pong when retryTransientErrors is enabled.
  • Drop the entity id from server-side entity RPC span names to keep cardinality bounded.

Bug Fixes

  • Fail the RPC server span when a response Exit cannot be encoded.

Upgrade Notes

If you parse the entity ID from server-side RPC span names for observability, it has been removed to reduce cardinality. Ensure your monitoring tools can handle the new span naming scheme. The RPC library updates improve error handling and interrupt propagation during handoffs.
