Buffer memory management #1

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
R-tree framework v1 used managed memory to store buffered data. It's not
good for performance at all. Using unmanaged system memory pages pinned
onto phisical memory frames is not jast faster, it allows to use system
"dirty" watch. And it's much more easy to use overlapped, async and
"lift-like" io.

Also, i'd like to say about dimension`s count. I'm using R-tree in
olap-like db for multidimensional aggregating of data. 2d-data case is
realy seldom, in most of cases system works with 10d - 12d data.

Most of my code devoted to indexing is not property of my employer, i'd
like to share it.

PS. I'm sorry, my English is still very poor to explain clearly what i'm
talking about.

what if the data is table or tuple in the database it adds to the futher 
complications i definatly need to know the indexing in R* tree for those 
objects

Can't get the point. Couldn't you use punctuation to split text to sentences?
