Postgres-XC Google Summer of Code 2010

Postgres-XC (previously also known as Postgres-2) is applying for Google Summer of Code 2010.

The idea list for contributions include:

  • Support for multiple coordinators. Secondary coordinators register with the primary coordinator. DDL (CREATE TABLE, etc.) goes first through primary coordinator, which synchronizes changes amongst the nodes. Long term we also allow for tracking if secondary coordinators are out of date, and for copying over catalog information to the secondaries.
  • Add support for cursors, first for forward only without ORDER BY.
  • Backup & Restore
  • Expand capability of pooler to handle session parameters.

We prefer to focus on the first item, support for multiple coordinators
