Hi,

I have been doing a lot of reading on Ancestor queries because we are 
currently trying to transfer from Master / Slave to the High Replication 
datastore.

We have noticed while testing on the HRDS, that sometimes when adding an 
entity and redirecting the view to show that entity (or maybe a list 
containing others as well), it can take a while for it to update because it 
is eventually consistent. (which is sometimes inconvenient)

I understand that you can not put an entity into an entity group once 
already created, the process of creating that entity so it is in a group 
has to be done the first time round.

I was just wondering that if we kept our older entities and started doing 
ancestor queries to insert new ones, can we merge the results to produce 
and output? I think if we can, it will have to be done in 2 queries, and if 
it can, will we no longer see a delay in data being updated?

Thanks,
Mark
