I think that your main issue here is not retrieval but storage. You say that you have a sizeable array of segments (> 100K). Are these all held in memory? If they are, it's a simple matter of using a slice, as in @foo[50000..100000].

Assuming that your data is not in memory, it must be on disk somewhere, in a flat file, or possibly a database. n the latter case, your retrieval then becomes a matter of SQL, as in: 

select * from foo where ID between 50000 and 1000000
