Everything in Oracle ZFS is great and it's easy to use, making it very user-friendly. I have used Oracle ZFS Snapshot and Rollback capabilities, and everything has worked well. The Snapshot and Rollback features in Oracle ZFS are awesome - that's one word to describe it. It's cool, very easy, and stress-free. Without doing benchmarks with other products, I can rate data compression in Oracle ZFS about an eight or nine out of ten, and I have noticed some deduplication and indexing features. Regarding how Oracle ZFS handles demanding workloads, such as online transaction processing and complex query executions, most of these aspects depend on your configuration setup. For instance, if you are using virtualization and have enterprise solutions on these servers, you can route or place database servers on SSDs or flash disks to enable better throughput from these systems. You can run your operating system on flash disks, or alternatively save ordinary data on SATA disks, depending on where you place your valuable data. The structure will affect performance, so if you plan it properly, you can achieve the best performance, even if the systems are aging or if you don't have the compute power, you can still balance it.
