Camera Raw/Bridge: 7.1 rebuilds Bridge cache

I just installed ACR 7.1 on my system. I used Bridge6 as my entire DAM system for my 700,000 images. For some reason, it now wants to reconstruct my "thumb nail extractions + cache". As far as I can see, there is no reason for this reconstruction.

I originally ran into this problem (and reported) with the 7.1 RC. I erroneously assumed that this was a bug in 7.1 RC but would be fixed in the final release.

I am in the process of reconstructing the cache file system to comply with SQLlight format requirements. Of my 700,000 images on my network drives, I have so far rebuilt the new cache system for 380,000 images and am waiting for the new release of Bridge which (I am told), will allow 1,000,000 or more entries in the cache structure. This has taken 10 elapsed days of 24 hours per day of processing on a dedicated second computer for the 380,000 images.

However, this update of ACR has, for practical purposes, negated my entire 10 days of system reconstruction - I effectively have to reprocess the cache yet again !!!!! I find this to be a very distressing and time consuming when new versions of ACR choose to capriciously reconstruct cache for no apparent gain.

I also surmise that the reconstruction will take even much longer since it seems that the raw files have to be completely reprocessed and thus negate the use of the BridgeCache files recorded in every image directory.

Imagine what would happen when I get to 1,000,000 images in the cache in the next (estimated) 18 months. A "neat new feature" of ACR would cause, on my system, 30 or many more days of continuous process.

To compound the problem, the new Fuji and two new Canon cameras are ones that I wish to use with the new ACR.

There is NO WAY to disable this unnecessary reconstruction from within Bridge.

What is the recommended way to return to ACR 7.0 so I can avoid this unnecessary processing (assuming that this will solve the problem). Can I download the 7.0 edition and install it? Do I have to re-install CS6 from the distribution disk?

Please please, make a Bridge option to not reprocess images due to changes in ACR. The only time the cache should need to be changed is when an image is actually "opened" in ACR for manual processing and/or passing to PS6. This would greatly assist those who use Bridge as a DAM and rely on its practical usability and stability.

I wonder if the new lightroom 4.1 has this problem of catalogue reconstruction? If it does not, it almost seems as though I should switch to Lightroom as my catalogue repository purely because of the performance penalty of Bridge/ACR.

After the 7.1 ACR update, I do see Bridge rebuilding the thumbnails/previews for previously cached folders. For me, the recompute is only happening when I go to that folder in Bridge the first time after the 7.1 ACR update.

It happens in CS5 Bridge too, it's quite disconcerting wasting all that time.

I agree Richard - I wish Adobe would allow US to control if the reconstruction is done. Maybe it does not matter if you have few images or if you visit your archives rarely. For me, my archive is very large, important, and in frequent use.

Dealing with the Cache in Bridge is the biggest problem with Photoshop, yet Adobe doesn't really seemed to be concerned with it.
