Interesting! Thanks for that, good to know. Looks like they use a redo log read mechanism along the same lines as Delphix and likely inspired by Goldengate. Only way to ensure synch without internals and shared memory peeking.

We been looking at the whole Hortonworks stack and it looks very good. But the problem with all these BigData products is always the same: they require a fully dedicated person who ends up being the only one who can mine and extract data. Mostly because of the absence of any schema metadata. While with relational dbs anyone with basic knowledge of SQL can pop-down and start producing consistent reports and logic in a very short time.

Yes, we're back to the bad old days of hierarchical and network db data lockdown...

Cool! Thanks for sharing that - it's quite relevant to us as well. CLOBs - and LOBs in general - are the Achilles Heel of Oracle. High time Oracle development got the clear message to fix the blessed things and make *LOBs truly usable instead of a source of easy consultant contract work to clean-up/re-organize/control/manage. But unfortunately - and this is IMHO one of the abysmal failures of the entire ACE program - they totally ignored user and ACE feedback on possible improvements and directions for the product. I know from talking with various ACEDs they asked for a lot of improvements over the years which never got the light of day. Most unfortunate.

Ah well, I'm quite sure Larry's announcement on the 1st June is going to change the entire cloud.
