Location in filedatastore doesn't match with dam:sha1 value

Dear Experts,

When a bunch of images are uploaded to AEM instance with 6.3.3 version having separated datastore, all images are uploaded successfully and proper jcr content fields are allocated. But, when I tried to locate the image(file) specified in dam:sha1 field in filedatastore, I neither found the image nor folder taxonomy.

Could you please point me in the right direction?

Kind regards

Sid

Had a session with Daycare support, content saved in jcr is with sha1 value and format with which folder taxonomy/ file saved in datastore is with sha256 value. Unfortunately, we can't track it unless we make any additional customizations out of adobe's scope.

Thanks

Anyway, this information is an implementation detail of AEME (or Oak, to be more precise). It may change without further announcement. Do not rely on it.

(and I am quite sure, that the presenter mentioned it at some point, but did not refer to it as feature which can be used at will.)

Ok, might be good to follow up on this. Can you start an conversation with the presenter (or the AEM gems team), point out your problem and also give the link to this forum thread. Would be good to have this resolved.

Thanks,

Jörg

This is for validations. In the AEM Gems presentation, the presenter mentioned that filedatastore follows the pattern of folder names extracted from the sha value of the blob.

Try calculating sha256 and look up that path. I am not sure if this applies to file datastore, but for S3 it now uses sha256 instead of sha1

Sure,

Configurations for "org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore.config", file we specified are as below:

path="/app/datastore/current_datastore"

service.pid="org.apache.jackrabbit.oak.plugins.blob.datastore.FileDataStore"

minRecordLength="1024"

Now when the image is uploaded jcr content says: f17de40d1a85c8b822f81cd87b3dd04f1d31f394

dam:sha1

String

f17de40d1a85c8b822f81cd87b3dd04f1d31f394

As per sha value "f17de40d1a85c8b822f81cd87b3dd04f1d31f394", when I navigate to filedatastore, I should see folders

f1--> 7d-->e4-->f17de40d1a85c8b822f81cd87b3dd04f1d31f394. But, I could only see folder f1 there is no 7d sub-folder.

Thanks
