Alexey, Thanks for details! Common replication infra suggestion looks great! Agree with your points regarding per-page replication, but still have a feeling that this protocol can be made compact enough, e.g. by sending only deltas. As far as entry processors we can decide on what to send - if the serialized processor is of smaller size then we can send it instead of the delta. This can sound like an overcomplication, but still good to measure.
Regards, Yakov
