Sharding on a … WebbA shard key on a value that increases or decreases monotonically is more likely to distribute inserts to a single chunk within the cluster. This occurs because every cluster has a chunk that captures a range with an upper bound of maxKey. maxKey always compares as higher than all other values. grand rapids flight to floridaWebbSo, a good shard key should not be monotonically increasing. In case of compound shard key, since it includes "_id" field it would be unique for each document. Therefore, it makes a bad choice for shard key as all the chunks would be dumped on one shard.
