s/"this single homing the reads"/"this single homing of the reads"

s/becomes/become/ (the second becomes)

Its not MTTR, it is the recovery process that has 3 phases.

s/would not be/will not be/

What is 'High Available Reads'.  Is that this feature?  Its not called timeline 
consistent reads or some such? 

s/from the previous model/from the current model/ (should it be 'current' or 
'original'?)

s/still has to go/still have to go/

s/be thought as/be thought of as/

Remove '... where the client can read from. '

May be note that the async writes are to keep the secondary's in-memory state 
up-to-date (since they are sharing the region data files)

"..so that there is no extra storage overhead. " -- add note that there may be 
some extra memory consumption though?

Do I have to turn this on cluster-wide or by table?  If the latter, maybe 
caveat your 2-3X memstore usage....

s/ high available reads/ highly available reads/

Ain't stochastic balancer on by default?  If so, why mention it in your configs 
section?  Might confuse?

You don't say what the below does:

 {REGION_REPLICATION => 2} 


is it turning it on or setting replicas to 2.  Clarify?

Excellent doc [~enis]
