Reference documentation and code samples for the Cloud Spanner V1 Client class Range.
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.

__construct
Constructor.
data
array
Optional. Data for populating the Message object.
↳ start_key
string
The start key of the range, inclusive. Encoded in "sortable string format" (ssformat).
↳ limit_key
string
The limit key of the range, exclusive. Encoded in "sortable string format" (ssformat).
↳ group_uid
int|string
The UID of the paxos group where this range is stored. UIDs are unique within the database. References Group.group_uid
.
↳ split_id
int|string
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.
↳ generation
string
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.
getStartKey
The start key of the range, inclusive. Encoded in "sortable string format" (ssformat).
string
setStartKey
The start key of the range, inclusive. Encoded in "sortable string format" (ssformat).
var
string
$this
getLimitKey
The limit key of the range, exclusive. Encoded in "sortable string format" (ssformat).
string
setLimitKey
The limit key of the range, exclusive. Encoded in "sortable string format" (ssformat).
var
string
$this
getGroupUid
The UID of the paxos group where this range is stored. UIDs are unique
within the database. References Group.group_uid
.
int|string
setGroupUid
The UID of the paxos group where this range is stored. UIDs are unique
within the database. References Group.group_uid
.
var
int|string
$this
getSplitId
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.
int|string
setSplitId
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.
