Postgres-XC is a write-scalable clustering solution based on PostgreSQL and uses a synchronized multi-master architecture. Postgres-XC is designed to make a cluster of multiple nodes seen as one unique transparent database to external applications. It uses a shared-nothing architecture and provides write-scalability by distributing data among nodes of the cluster. It is under PostgreSQL license.

Structure of Postgres-XC makes possible to build viable database clusters with commodity hardwares, transparently to the applications. It provides a PostgreSQL-like interface to the applications, making it easy for porting the applications. The high-availability features that are currently being developed are based on PostgreSQL synchronous streaming replication and HOT Standby. Postgres-XC has built in algorithms to avoid any single point of failure in the cluster. Postgres-XC has demonstrated a 3.6 scalability in a cluster of 5 nodes. Development team is currently working on integrating Postgres-XC functionalities within the core engine of PostgreSQL so that they can later be merged in the core PostgreSQL.

We will present Postgres-XC's core architecture, key-algorithms, the achievements of the projects till date, high-availability features (HA) as well as the next steps of development and the road map of the project leading to version 1.0.
