Each server is referred to as a database shard. Sharding a multi-tenant app with Postgres Whether you’re building marketing analytics, a portal for e-commerce sites, or an application to cater to schools, if you’re building an application and your customer is another business then a multi-tenant approach is the norm. On Google Cloud Platform, Cloud SQL and ProxySQL services can be used to shard PostgreSQL and MySQL databases. On AWS , Amazon RDS is a service that can implement a sharded database architecture. I can't see how that could be done transparently short of something like Oracle RAC. For sharding PostgreSQL, PL/Proxy, Postgres-XC/XL and Citus can be used. In version 11 (currently in beta), you can combine this with foreign data wrappers, providing a mechanism to natively shard your tables across multiple PostgreSQL servers. In this episode of Scaling Postgres, we discuss setting up active-active instances with federation, the impact of memory speed, the causes of table rewrites and the Postgres shibboleth. :) -- When fascism comes to America, it will be intolerance sold as diversity. Benefits of Sharding. Horizontal Scale via Sharding. Citus 6.1 brings several improvements, making scaling your multi-tenant app even easier. Sharding. I also know it is possible to just shard at the application layer (and I am doing so already) but the big limitation there is the inability to do joins across the nodes (linked servers are unusably slow for this). In this case, we’ll need to add a load balancer to distribute traffic to the correct node depending on the policy and the node state.

Segfault : PostgreSQL 9.0.0 and PgPool-II. pg_shard is a sharding extension for PostgreSQL. This is often contrasted with vertical scaling, otherwise known as scaling up, which involves upgrading the hardware of an existing server, usually by adding more RAM or CPU. Cheers, David. Horizontal Partitioning (sharding) stores rows of a table in multiple database clusters. [PROPOSAL] Effective storage of duplicates in B-tree index. It’s often not until over 100 GB of data that you need to think about sharding.

The technique for distributing (aka partitioning) is consistent hashing”. There are agents running on each of the nodes that handles the inter-node communication allowing it to be transparent to the calling application. Sharding or horizontal scalability is a popular topic, discussed widely on PostgreSQL mailing lists these days. Yes, but it depends on the SQL in your client code. If you use inheritance and therefore put the child tables on the same server, it's invisible to the client that the table is partitioned.

Existing PostgreSQL forks for Sharding. When to Use Citus. Horizontal Scaling In addition to scaling your master database vertically, you can also improve the performance of a read-heavy database by using read replicas to horizontally scale your database. We already have one database per client (an SaaS environment). All database shards usually have the same type of hardware, database engine, and data structure to generate a similar level of performance.
