Schema Update large refactoring

#1

Hello,

we want to perform a major refactoring of our package names and hence need to do an automatic schema update of our database using the objectdb.conf file.

The old package structure looks like this: "com.btc.ep.*, while the new one will be "ep.*", where "*" can be any number of "sub"-packages (e.g. com.btc.ep.details.viewer.impl" -> "ep.details.viewer.impl").

We are now wondering, if it is possible to perform some sort of wildcard schema update, instead of specifying all the thousands of packages that we have individually.

Furthermore, if we have to specify them individually, will there be any limit to the number of packages that we can specify? Will the number impact performance?

 

Thanks in advance :)

Wildcards are not supported.

No.

Probably not much (and only when the database is opened).
