Shard Key Indexes. All sharded collections must have an index that supports the shard key. The index can be an index on the shard key or a compound index where the shard key is a prefix of the index. If the collection is empty, sh.shardCollection() creates the index on the shard key if such an index does not already exists.

After that command you have three chunks: min_value -> 0. 0 -> 1000. 1000 -> max_value. The three following commands moves these chunks to separate shards. The docs say that the command will move the chunk containing ...
Feb 14, 2024 · Database sharding is a data architecture strategy that increases database performance by splitting up data into chunks and then spreading these chunks “intelligently” across multiple database servers (or database instances). These chunks of data are called shards, while each shard contains a subset of our data.
Jul 6, 2023 · Only performance testing different numbers of shards, and by association different shard sizes, can determine the ideal number of shards for your index. This given, a good place to start is with a number of shards that gives your index shard sizes between 10–50 GB per shard. Specifically, 10–30 GB per shard is preferred for workloads that ...
