#version ⇒ Integer

Returns The version of the entity, a strictly positive number that monotonically increases with changes to the entity.

This field is set for +FULL+ entity results.

For Missing entities in +LookupResponse+, this is the version of the snapshot that was used to look up the entity, and it is always set except for eventually consistent reads.
