Hi!
Since I came into this topic while writing a script: What does
DBD::Oracle know about bulk operations?
In PL/SQL you can speed up your cursor loops by using bulk fetches
and/or bulk updates/inserts. Instead of operating on single rows you use
arrays of rows. Since DBI does not support it directly (from what I
know), it could be used when doing select_all_xxx calls. Sounds simple,
and, yes, I know, it is not as easy as it sounds. But I think it would
speed up this calls. PL/SQL gets a boost by 5 to 10, depending on
hardware, OS and other things.
When you search for DBD::Oracle and bulk, google only comes up with
rather old documents dating back to 2004 and 2003. In one of those (from
this mailinglist) I found:
"It is not part of DBD::Oracle yet, though there are plans to include
it in a future version."
I'm a regular reader of this mailing list and I wonder that this topic
did not come up again in recent years - or I just missed it ...
