A Range
represents a range of keys in a database. The keys themselves
are encoded in "sortable string format", also known as ssformat. Consult
Spanner's open source client libraries for details on the encoding.
Each range represents a contiguous range of rows, possibly from multiple
tables/indexes. Each range is associated with a single paxos group (known as
a "group" throughout this API), a split (which names the exact range within
the group), and a generation that can be used to determine whether a given Range
represents a newer or older location for the key range.

getGeneration
()
generation
indicates the freshness of the range information contained
in this proto. Generations can be compared lexicographically; if generation
A is greater than generation B, then the Range
corresponding to A is
newer than the Range
corresponding to B, and should be used
preferentially.

within the database. References Group.group_uid

A group can store multiple ranges of keys. Each key range is named by an
ID (the split ID). Within a group, split IDs are unique. The split_id
names the exact split in group_uid
where this range is stored.
