issue: #46087 The previous implementation checked if the total number of ready delegators >= replicaNum per channel. This could cause target updates to block indefinitely when dynamically increasing replicas, because some replicas might lack nodes while the total count still met the threshold. This change switches to a replica-based check approach: - Iterate through each replica individually - For each replica, verify all channels have at least one ready delegator - Only sync delegators from fully ready replicas - Skip replicas that are not ready (e.g., missing nodes for some channels) This ensures target updates can proceed with ready replicas while replicas that lack nodes during dynamic scaling are gracefully skipped. --------- Signed-off-by: Wei Liu <wei.liu@zilliz.com>
