Stork cannot connect large Kea installation
name: Stork cannot connect large Kea installation about: Stork 0.10 is unable to connect to agent when there a large number of subnets defined in Kea (1.8).
KEA 1.8.0 today and installed Stork 0.10, I noticed that Stork server can't connect to my large instances (with ~4500 subnets) and I see the following errors logged in Events tab:
grpc manager is unable to re-establish connection with the agent 192.168.1.5:8080: rpc error: code = ResourceExhausted desc = grpc: received message larger than max (4607854 vs. 4194304)
According to the gRPC doc there are two functions to set maximum sizes:
The default seems to be 4MB (confirmed by the error message).
Another idea is to use compression: JSON should be very easy to compress efficiently...
