v.23.4Experimental Feature

Implement zero-copy-replication on encrypted disks

Implement zero-copy-replication (an experimental feature) on encrypted disks. #48741 (Vitaly Baranov).
Implemented zero-copy replication for tables stored on encrypted disks as an experimental feature.

Why it matters

This feature addresses the challenge of efficiently replicating data on encrypted disks by enabling zero-copy replication. It improves performance and reduces resource usage during replication by avoiding unnecessary data copying, while maintaining encryption security.

How to use it

To use zero-copy replication on encrypted disks, enable the experimental feature in the server configuration and create replicated tables on encrypted storage disks as usual. Ensure the experimental flags related to zero-copy replication and encrypted disks are set according to the documentation.
