Description
In this commit: https://github.com/scylladb/scylla-cdc-java/commit/77abc2358678809d08b3084aafc57d49cd6559df, getUnsafeBytes was introduced back. This API could make the replicator source code easier, eliminating the need to translate between different representations.
Additionally, the replicator now manually groups delta rows with pre/post-image. When a new API is introduced that performs this pairing automatically, the replicator should be switched to use this API.

Research direction
Read commit 77abc2358678809d08b3084aafc57d49cd6559df and inspect the replicator source code to identify the representation translations and manual grouping of delta rows with pre/post-image. Confirm that the referenced APIs support both changes, then migrate the replicator and verify that its output remains equivalent.
