By vertical sharding we mean a process of increasing application scalability by separating out some number of tables from the main database, into a dedicated database instance to spread both read and write load. Vertical sharding is often contrasted with “horizontal” sharding, where higher scalability is achieved by adding servers with identical schema to host a slice of the available data. Horizontal sharding is generally a great long-term solution if the architecture supports it, but vertical sharding can often be done quicker and can buy you some time to implement a longer-term redesign.
