AFAIK, Java UDFs is a idea of Jim Starkey, but since I don't
read the development mailing list, I have no idea if it is a pro-
ject running and if will release something to IB 7.
Search http://firebird.sourceforge.net on how to get this info
on development mailing lists.

I heard the largest C/S app knew to the moment is something
like 600 concurrent connections on the same server.
Webapps normally have a connection lifetime very shorter than
normal C/S application. So,
with 600 concurrent connections you can do much more than
this. A connection (considering a connection pooling capable
server and app) can easily multiply it to 3 or 4 times. This is a
rather poor estimative, anyway - it could be much more.

Transaction logs... Not build on engine, but available on third-party
products. See www.ibphoenix.com or www.interbase2000.org for
links on third-party tools.

1 million? No. This is not a "table barrier", it was discussed
A LOT on Mers and IB-Support also. Synthesis of the opera:
db files larger than 2Gb must be partitioned to Firebird work
ok There are a bug on IB that makes 2Gb the safe limit FOR FILE.
Since you can have 65536 of these files... See if the firebird
development leaders if they corrected THIS. Ib-Support group
would be a nice place to ask. Anyone can confirm this?
Multi-file databases are explained very detailed in documentation.

>because i have some blobs there

Except very little blobs, they are not stored on the table pages -
they heve it's own pages. Not a problem - and no need to have
a separite table for the blobs (as in MSSQL).

A connection pooling mechanism can multiply the number of
connections available.

4.3 billion (2^32) rows is enough for you?

Netfras*.* is Jim personal project. He seems to
want to make Firebird follow the right steps of
Netfras*.*...

In servers, it's ok... Embedded on another apps.... hmmmm...

the actual scheme it will be not a problem...)
