Michael Dürig commented on OAK-5902:
------------------------------------

bq. memory consumption

Agreed, increasing the heap for the tests is problematic and we shouldn't do 
this. At least we need to understand where the memory requirements come from: 
is it the test or the code?

> Cold standby should allow syncing of blobs bigger than 2.2 GB

> 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.
