btree page merging

Hello!

I recommend two good sources of information in English:

http://www.nist.gov/dads/ further look for balanced trees and kins

(BTW, there is some other interesting algorithms alike patricia).

and well-known Donald Knuth's monography, namely, volume 3. (I mean
"The Art of Computer Programming".)

its description can be found at
http://www-cs-faculty.stanford.edu/~knuth/taocp.htm

You can also look at how MUMPS (where B+trees is the "heart" of
DBMS) handles B+trees if curious:
