Next in this trackOne app instance keeps flapping out of the load balancer pool, yet between bursts it serves traffic happily. Where do you look?Next in this trackRedis latency spikes for a few hundred milliseconds every couple of minutes, right around each background save. What is your hypothesis?Next in this trackWe doubled Kafka's partition count to fix growing lag, and lag grew instead. Walk me through what a rebalance does to a group.
