Hi, We are noticing there is quite a bit of delay when we reload the config with traffic_ctl config reload. The delay is up to about 30 seconds, during which period we don't get any caching. We are using consistency hashing plugin. The number of nodes changes dynamically between 5 to 30.
Here is an example balancer (consistent hash) configuration in remap.config. map / http://127.0.0.1 @plugin=cachekey.so @pparam=--include-params=p0,p1 @pparam=--sort-params=true @plugin=balancer.so @pparam=--policy=hash,key @pparam=123.123.123.1 @pparam=123.123.123.2 @pparam=123.123.123.3 @pparam=123.123.123.4 ... Is this downtime normal? How do you guys avoid the service downtime while reconfiguring the cache nodes in the cluster? Hobin
