'Jonathan Corbet, writing at LWN: In the fast-moving open-source world, programs can come and go quickly; a tool that has many users today can easily be eclipsed by something better next week. Even in this environment, though, some programs endure for a long time. As an example, consider the PostgreSQL database system, which traces its history back to 1986. Making fundamental changes to a large code base with that much history is never an easy task. As fundamental changes go, moving PostgreSQL away from its process-oriented model is not a small one, but it is one that the project is considering seriously. A PostgreSQL instance runs as a large set of cooperating processes, including one for each connected client. These processes communicate through a number of shared-memory regions using an elaborate library that enables the creation of complex data structures in a setting where not all processes have the same memory mapped at the same address. This model has served the project well for many years, but the world has changed a lot over the history of this project. As a result, PostgreSQL developers are increasingly thinking that it may be time to make a change.' -- source: https://tech.slashdot.org/story/23/06/19/1723259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
