Thanks Richard. We came to the conclusion that leaving the data in the
Maria database, and not invoking the DB2 engine would be the best approach
in this case.
Reasons:
1) we don't really gain that much, we can access the data from other open
source projects on IBM i and move what's needed into/out of DB2 at will.
2) As Jon pointed out, the column names would become a nightmare. The
application we are using is open source with some modifications so changing
column names to be more sane is not reasonable or possible.
3) Performance is excellent at this point and I doubt that when the database
gets loaded up some it will vary by much if any at all.

If the MariaDb database is working fine I would not suggest moving it in to
DB2 storage engine unless you want to use the same data from an RPG
application.
I can't imagine the performance would really be noticed on a small site
unless you just want to do it as a technical exercise.
I haven't run in to any customers using the native DB2 engine and don't know
how much if any effort is still going in to it.

Yes default, which I believe is innodb.

I've never heard of a "native" storage engine for MariaDB. Do you mean the
"default" storage engine, which is supposedly
https://mariadb.com/kb/en/innodb/? Actually, I'm not sure what the default
storage engine is for PHP on IBM i. The phpMyAdmin dialog for creating
tables has a drop-down list of about eight possible storage engine options.

exactly what I'm asking. Yes, I would ordinarily agree with you but,
is it worth the extra work to move the data?

When you say "leaving it in Maria", what storage engine are you
referring to (i.e. MyISAM, InnoDB, CSV)? My intuition says that using
the IBMDB2i storage engine would perform better than a storage engine
that referenced a bulk IFS file. But I haven't seen any benchmarks to
prove it.
