using java to create a key-value database for high-performance
computing, is it a stupid idea?
thanks

Yes, a little. There are lots of databases already available, use one
of them.

Depending on what one means by "database" and its projected size, one
might need no more than a standard 'Map'.

If that's not quite enough, use Derby (a.k.a. "Java DB", included with
the JDK) or PostgreSQL.

Some large internetsites use this idea. Maybe
http://hadoop.apache.org/hbase/ is what your looking for.

No. That is quite common.

But if you have to ask here, then I don't think a multi
billion dollar company has hired you to design their
new PB size databse.

For ordinary computing a relational database is
ready to be used.

If you like the key-value API, then use a table with
a key field and a BLOB value field.
