I have a test greenplum cluster, it supports postgres 8.3 SQL language/functions etc,
I have a query that it should finish in about 30 minutes but instead it just keeps running on end, it fills the filesystem and then die
I need someone that knows SQL very well, has experience with columnar database and how they work (example no indexes etc) and that it can properly read and understand query plans
I will provide the query and more details later
My apologies for being blunt, but it appears that many providers are not reading the requirements
This is not a web project, so please unless you have years of SQL experience and you know GreenPlum or similar columnar databases (Vertica etc), you are wasting your time and my time
