What are the benefits of data partitioning in a database?
Improve scalability. When you scale up a single database system, it will eventually reach a physical hardware limit. If you divide data across multiple partitions, each hosted on a separate server, you can scale out the system almost indefinitely. Improve performance.
How much data can be stored in a logical partition?
Each logical partition can store up to 20GB of data. Good partition key choices have a wide range of possible values. For example, in a container where all items contain a foodGroup property, the data within the Beef Products logical partition can grow up to 20 GB.
When to use only or drop constraints in PostgreSQL?
Using ONLY to add or drop a constraint on only the partitioned table is supported when there are no partitions. Once partitions exist, using ONLY will result in an error as adding or dropping constraints on only the partitioned table, when partitions exist, is not supported.
