Hi Vinicius,
We are aware of this problem and came up a while back with several
solution ideas such as caching the metadata or storing it in a local/
remote repository. Changing the schema format, though, also requires
changes in the query builder. Due to tight schedules and higher
priorities we never had the time/man power to get to it. We always
look forward to new Kepler contributors and would be happy if someone
could dig into it.
Cheers,
Efrat
