Adobe Exam AD0-E123 Topic 1 Question 10 Discussion

When using a Network File System (NFS) for AEM, CachingFileDataStore is recommended because it caches binary data on the file system and stores only references to the binaries in the repository. This can be beneficial for performance, as it reduces the latency associated with reading binaries over the network, especially when NFS is being used. The caching layer helps in optimizing read operations by keeping a local cache of frequently accessed data.

S3DataStore is used when integrating with Amazon S3 for storage.

FileDataStore does not provide caching capabilities and would not be as efficient as CachingFileDataStore when using NFS.
