Daniel Petisme updated DRILL-6012:
----------------------------------
Priority: Minor (was: Major)
Description:
Oracle backups are stored under a RMAN (Recovery Manager) format.
https://docs.oracle.com/cd/E11882_01/backup.112/e10642/rcmquick.htm
With the raise of BigData, we want to query all possible data. Nevertheless, is
sometimes hard to get access to actual living data where backups are often easy
to get but hard to restore properly.
The aim of this feature would be to query the RMAN file without actually
restoring the database. I don't know if it's even feasible but would be a great
help to ease the data access.
As far as I know, RMAN are binary formats (I guess propriatary) which contains
some structure meta-data (indices, for instance) and the actual data.
IMHO, in that context performance is not a first-class constraint is more an
exploration tool I have in mind.
Does make sense? What's you thoughts on this idea ?
