Webb7 okt. 2024 · Sharding With Azure Database for PostgreSQL Hyperscale. As I mentioned earlier in this guide, “sharding” is the process of distributing rows from one or more tables across multiple database instances on different servers. The advantage of such a distributed database design is being able to provide infinite scalability. WebbMongoDB Documentation
Webb2 apr. 2024 · Range sharding allows for efficient shard key range scans but can result in “hot” chunks if the shard value is monotonically increasing. Hash sharding: In hash-based sharding, keys are distributed based on a hash function applied to the shard key. The balancer: MongoDB tries to keep the data and workload attributed to each shard equal.

For such keys, ranged sharding causes a particular shard to get a bulk of read and write operations and mitigates the benefits of sharding. sid thompsonWebbSo, 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, sid thomson photography
