Hi All,

 

Thought I’d give this one more try.

 

Has anyone used ExtenDB?  Our company is going to be putting a database server cluster in the coming months and we would like some feedback from anyone who has used ExtenDB as to what their experience with it has been like.

Haven't had any experience with it myself, and haven't heard anything
from them apart from a couple of announcements. There is another company
doing something similar called "greenplum" who I don't think offer a
free download of their multi-node system, but do have
manuals/white-papers etc. available for download after you register.

Both systems seem to be using the same partition-and-replicate system to
distribute queries across multiple nodes. This is straightforward enough
in theory but a lot of work in practice. The two things that will make a
difference are efficient use of the interconnect (gigabit ethernet for
both by the look of it) and the quality of the management tools.

Anyone from ExtendDB like to step forward and point Gary towards some
existing users?

Thanks for the reply Richard.  I will take a look at greenplum also.
