- Filesystem federation is currently read-only (though we plan to enable writable filesystem federation soon once a few outstanding issues are resolved).
- Access control can currently only be applied to an entire federated filesystem, not different access controls for different directories/files.
- Transactions are not available.
- Versioning is not available.
- Querying using the internal search functionality (including calculating object and byte counts in the repository root) results in every file and directory being accessed each time the caching timeout expires (this is set with the
cacheTtlSecondsparameter). For federations with large numbers of files, this can take a long time and result in "Too many open files" errors as files are opened faster than Java garbage-collects them.
