Yifan Cai commented on CASSSIDECAR-394:
---------------------------------------
Trying to understand the problem. "delay=10ms" is way too frequent. The default
delay is 5 minutes when active in production. It should not be configured to
run every 10 milliseconds.
The log provides useful summary of the discovery round. Given it is logged
every several minutes. Do you think it is still too verbose?
