This release focuses on scaling up Global Resource Service (GRS) to support total 5 million nodes come from different regions.

Highlights include:

  • In regular node status change scenario, GRS delivers 99% of node status changes to consumers (schedulers) within 90 milliseconds
  • In massive node outage scenario (5M nodes have status changes), GRS can deliver all events to consumers within 1 minute
  • Latency and throughput data:
Test Case Watch Latency (ms) List (ms) Register (ms) Throughput
(events/s)
P50 P90 P99
Regular changes 32 73 88 1,389 64 N/A
Massive outages 23,606 44,900 47,810 1,381 66 96,241

Detailed test configurations are listed here.
