HI.
Thanks, Heikki, for the answer on google-melange. For some reason i didn't
receive email notification, so I saw this answer only today.
Do you have access to a server you can use to perform those tests? (...)
Yes, i have. I am maintaining MPI cluster in my university, so it is not a

* Don't do cube with type support
Eventually, there is different ways of reducing R-Tree size. For
example we can store relative coordinates with dynamic size of MBR (VRMBR),
instead of absolute coordinates with

Sounds promising. Did you examine how this technique can fit into GiST? In
current GiST interface methods don't have access to parent entries.
No, i didn't examine it yet. Anyway in this technique lots of changes should be
performed to

I think we have at least 3 data types more or less similar to cube.
1) array of ranges
2) range of arrays
3) 2d arrays
Semantically cube is most close to array or ranges. However array of
ranges have huge storage

Hi, Jey!
I remember I've started couple of threads related to cube extension:

Could you provide some feedback to GSoC proposal of Stas?

Hello,
some time ago I started working on the data search system (about 100-200M of
records) with queries consisted of several diapason and equality conditions,
e.g.:
WHERE dim1 BETWEEN 128 AND 137 AND
WHERE dim2 BETWEEN 4815 AND 162342 AND
WHERE dim3 = 42
ORDER BY dim1 ASC
There are
10 matches
