Hi Björn,

The database should persist "forever", even if the workflow is restarted.  I'm not sure about the distinction between forever and output data, but the database should remain in place until the user takes specific action to make it go away.

If you reload a tool, it will reload/extend the existing database.

If we have access to the user name, and can create user-specific data within one single database, that should address our needs.

Thanks!

Melissa

Good thing to clarify: this is a tool-specific database, created by tools
that are running inside Galaxy but that should persist after the individual
tools are done with their execution.

Should it persist as output data or forever even if I start my workflow from scratch?

What will happen to the db if I reload a tool and rerun it. Will it extend the database or will it use a new one from scratch?

You have access to the user name if you are running the tool. With that you can create a table for every user and store your data user-specific.

Cheers,
Bjoern

  Hi folks,

Hopefully this is a quick question.  I'm working on a set of tools that
will fire off a VM from within Galaxy and will then communicate with the
VM.  The VM will create a local database.


Are we talking here about a local Galaxy database or a tool specific
database?

best,
Bjoern


  The vision is that this won't be

a shared database; in a shared Galaxy instance, each user will have his or
her own database.  What is the best place to create this database under
the
Galaxy file system?

Thanks!

Melissa
