Automatic database sharding with Alibaba Cloud Table Store
At some point in your application’s lifecycle, there might come a time when you need to start scaling your data storage. If you are storing media files or other blobs that have no relations between them, you can easily add storage capacity to solve the problem. For (semi-)structured data in a database however, scaling is a whole different story. Simply adding database instances is not enough. You will need to reconsider the usage patterns and decide what solution solves the problem you have. If your database is hitting resource limits because it is accessed very frequently, adding an asynchronous read replica might be the way to go. If the size of the data is the issue and lookups become very slow, you might consider sharding your database.
