against specific branch: Upload a patch to a JIRA in the following format
HIVE-.patch, HIVE-.XX.patch, HIVE-.D.XX.patch

The read replicas doc mentions something a little more intrusive in the 3

Relatedly just as another strawman, for the mostly read only use case and
bulk load only usecases, why not use normal replication against two

A separate branch similar to that for snapshot is great. +1.
For wal tailing, we can just skip those edits not for the shadow regions,
right?
To tail the wal, we need to wait till the wal block is available. There
seems to be a hard latency. Is it better to have a pool of daemon threads
to ship
We don't have to ship the edits one by one. We can use a configurable
batch to control the impact on network.
