Postgres-XL is an all-purpose fully ACID open source scale-out SQL database solution.
There are a wide variety of use cases for Postgres-XL:
- Business Intelligence / Big Data Analytics
Postgres-XL has built-in MPP (Massively Parallel Processing) capability, with intelligent query planning, allowing you to use the familiar SQL language for handling queries over large data sets.
- Web 2.0
The data tier is typically the hardest part in scaling infrastructure. Postgres-XL allows for database scaling while preventing the database from becoming a bottleneck for applications, whether for Content Management Systems, or eCommerce websites.
- Legacy Applications
If hardware limits what a database can handle on a single server, Postgres-XL enables scale out across multiple nodes.
- New Applications
Right-scale new applications to plan for future growth by using Postgres-XL. One could also use regular PostgreSQL, and migrate to Postgres-XL later as the database activity increases.
