Accepted Google Summer of Code projects 2013
This year's accepted Google Summer of Code projects have been published . Among them are 3 accepted proposals for PostgreSQL which not only will be fine addition to PostgreSQL's set of features, but also helps introduce new students to our community for hopefully long-term contributions. The projects that will be worked on are: Cube extension improvement (Stas Kelvich) Indexes on the cube data type (in the "cube" extension) tend to be on the large size, meaning maintenance of and accessing these indexes is expensive. The improvements this project aims to implement are in reducing the cost of indexes on cube data by using r-tree structures. In addition to this, PostgreSQL's relatively new K-Nearest Neighbour framework would serve to allow the creation of ordering operators for retrieving sorted data directly from the index, and ordering operators for kNN with different spatial norms.
