Hi to all,
I'm a new ozone user and I'm trying to understand and solve the problems 
with
large lists (Balance between RAM cost and time performance).
I read in faqs that one solution to this problem -in case of  using 
standard java
collections- is to replace the collection with a linked list whose nodes 
are ozone objects.

Question1 : In case of such a linked list, how many ozone objects can I 
have without
affecting time performance?
           Question2 : I have a table of 300 million records(you see, I' 
m classic RDBMS developer)
and each record has a size of 10 bytes. How could I design the objects 
in order to use
ozone in this case?
           Request   : Please give me some hints or ideas on how to deal 
with the problems of large
lists in order to use ozone.
           Thanks in advance.

George Karousis
