Description

Currently there is a limitation for the maximum binary size (in bytes) to be synced between primary and standby instances. This matches Integer.MAX_VALUE (2,147,483,647) bytes and no binaries bigger than this limit can be synced between the instances.

Per comment at [1], the current protocol needs to be changed to allow sending of binaries in chunks, to surpass this limitation.
