Description

The persistent cache currently stores binaries up to one MB by default. However most of the BlobStore implementations already provide some form of caching. E.g. for S3 a cache on the local filesystem is maintained and when using a Jackrabbit FileDataStore the persistent cache is actually unnecessary.

Support for documents in the persistent cache should also be removed. In contrast to other cache entries, documents are mutable and may cause consistency issues when enabled with the persistent cache.
