-------------------------------------------------------------------
[~lvfangmin] It's understandable that this should be a configurable (on/off)
feature, however, I still advocate that it should be on by default. The snap
shot file contains Strings representing the ZNode paths and that path data is
almost certainly highly compressible. So even if there is compressed payload,
the metadata still will gain from compression.
Edit: That is to say, how common is it to store data in ZNodes or is the more
commons use case to simply use ZNodes paths to encode some sort of state...
i.e., service discovery or locking recipes.
