Sharding monotonic

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. WebbAvoid Monotonic Throttling If your shard key increases monotonically during an insert, then all inserted data goes to the last chunk in the collection, which will always end up on a …

Webbthe second shard will have 10M - 20M nodes, third shard will have 20M - 30M nodes, and so on. Date-based queries may produce results from only a subset of shards as DBID increases monotonically over time. Date/Datetime (DATE) This method is available in all versions of Search and Insight Engine. WebbSo, 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. This can be overcome by using hashed keys as follows,
