Active-Active Geo replication of hashes in Redis Enterprise

I am planning active-active geo replicated Redis Cache. If I update existing key, then how replication works for hashes.
I could not able to find any resource except https://docs.redis.com/latest/rs/databases/active-active/data-types/hashes-active-active/

I am storing Key and around 5KB Object as value in Hashes. If I update this hash, then what data will be replicated to other region? I am trying to calculate bandwidth between regions, however I am not sure CRDTs replicate complete object in case of update or just difference.

Any help would be appreciable!
Thanks in advance.

    @Chintan Patel Thank you your clarification.

    When using Active Geo Replication, the caches only need to send the delta, not the entire contents of the data structure. The cache only needs to replicate the differences in the hash data structure, not the complete object.

    Please let us know if you have any additional questions.
