…vus-io#34096) issue: milvus-io#34095 When a new query node comes online, the segment_checker, channel_checker, and balance_checker simultaneously attempt to allocate segments to it. If this occurs during the execution of a load task and the distribution of the new query node hasn't been updated, the query coordinator may mistakenly view the new query node as empty. As a result, it assigns segments or channels to it, potentially overloading the new query node with more segments or channels than expected. This PR measures the workload of the executing tasks on the target query node to prevent assigning an excessive number of segments to it. --------- Signed-off-by: Wei Liu <[email protected]>
