Hi Maxence, This is really really good. Hopefully we will have a fruitful summer, and make MADlib a better product. Thanks Hai -- *Pivotal * A new platform for a new era On Sat, Apr 5, 2014 at 7:14 AM, Maxence Ahlouche wrote: > Hi all, > > 2014-04-03 9:04 GMT+02:0

[HACKERS] GSoC 2014 proposal

Hello, hackers! This is my GSoC proposal. *Short description:* Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than to those in other groups (clusters)

Hi Greg, pgsql-advocacy, and pgsql-hackers, I'm interested in doing my GSoC project on this idea. I'm new to indexing and WAL, which I haven't encountered in my classes, but it sounds interesting and valuable to Postgresql. So here's my draft proposal. Do you mind giving your opinion and correc
