How tolerant of schema changes is the dump and load process? If a column is gone from the DB on load or a column has been added (that's probably simple), will this process succeed?
If so, I can see this tool being useful even in the fully hosted mode for some kinds of schema modifications. Appreciate your thoughts. I've had problems in the past getting schema changes to be applied without having to dump and rebuild my database so I'm looking for ways to modify the schema without wiping out all my beta activity. Thanks, and I'll be bookmarking the OS page in general :-) On May 6, 9:14 pm, "Adam Wiggins" <[EMAIL PROTECTED]> wrote: > We've got a new version of yaml_db online which has some substantial > optimizations contributed by Ricardo Chimal.
