Talking to the right shard

In this chapter, we have chosen to represent database shards as PostgreSQL schema names. So, if our basic schema is named myapp, shard 1 would be myapp1, shard 15 would be myapp15, and so on. This is what we call the logical shard name.

Beyond this, shards should be independent of each other such that they can be relocated to another PostgreSQL server arbitrarily. However, if shards can be moved at will, how do we find them? Much like LVM has a physical drive, logical shards have a corresponding physical shard. The physical shard is the server where the logical shard currently resides. Think of it like this diagram:

Elements such as clients, products, and vendors are shared resources that all PostgreSQL shard servers can use. This is where our foreign tables would be beneficial. The logical shards (schemas) myapp1 through myapp4 all reside on PG Server 1, and myapp5 through myapp8 live on PG Server 2. In this architecture, we have eight logical shards distributed...

Shaun Thomas

Shaun M. Thomas has been working with PostgreSQL since late 2000. He is a frequent contributor to the PostgreSQL Performance and General mailing lists, assisting other DBAs with the knowledge he's gained over the years. In 2011 and 2012, he gave presentations at the Postgres Open conference on topics such as handling extreme throughput, high availability, server redundancy, and failover techniques. Most recently, he has contributed the Shard Manager extension and the walctl WAL management suite. Currently, he serves as the database architect at PEAK6 Investments, where he develops standard operating procedure (SOP) guidelines to facilitate reliable server architecture among many other tasks. Many of the techniques used in this book were developed specifically for this extreme environment. He believes that PostgreSQL has a stupendous future ahead, and he can't wait to see the advancements subsequent versions will bring. https://www.linkedin.com/in/bonesmoses
