Overview

Type represents the type of data that is written to, read from, or stored in Bigtable. It is heavily based on the GoogleSQL standard to help maintain familiarity and consistency across products and features. For compatibility with Bigtable's existing untyped APIs, each Type includes an Encoding which describes how to convert to/from the underlying data. Each encoding also defines the following properties: * Order-preserving: Does the encoded value sort consistently with the original typed value? Note that Bigtable will always sort data based on the raw encoded value, not the decoded type. - Example: BYTES values sort in the same order as their raw encodings. - Counterexample: Encoding INT64 as a fixed-width decimal string does not preserve sort order when dealing with negative numbers. INT64(1) > INT64(-1), but STRING("-00001") > STRING("00001). * Self-delimiting: If we concatenate two encoded values, can we always tell where the first one ends and the second one begins? - Example: If we encode INT64s to fixed-width STRINGs, the first value will always contain exactly N digits, possibly preceded by a sign. - Counterexample: If we concatenate two UTF-8 encoded STRINGs, we have no way to tell where the first one ends. * Compatibility: Which other systems have matching encoding schemes? For example, does this encoding have a GoogleSQL equivalent? HBase? Java?

#aggregate_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeAggregate

A value that combines incremental updates into a summarized value. Data is never directly written or read using type Aggregate. Writes will provide either the input_type or state_type, and reads will always return the state_type . Corresponds to the JSON property aggregateType

Returns:

# File 'lib/google/apis/bigtableadmin_v2/classes.rb', line 3610

def aggregate_type
  @aggregate_type
end

#array_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeArray

An ordered list of elements of a given type. Values of type Array are stored in Value.array_value. Corresponds to the JSON property arrayType

Returns:

# File 'lib/google/apis/bigtableadmin_v2/classes.rb', line 3616

def array_type
  @array_type
end

#bool_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeBool

bool Values of type Bool are stored in Value.bool_value. Corresponds to the JSON property boolType

Returns:

3622
3623
 
# File 'lib/google/apis/bigtableadmin_v2/classes.rb', line 3621

def bool_type
  @bool_type
end

#bytes_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeBytes

Bytes Values of type Bytes are stored in Value.bytes_value. Corresponds to the JSON property bytesType

Returns:



3626
3627
3628
 
# File 'lib/google/apis/bigtableadmin_v2/classes.rb', line 3626

def bytes_type
  @bytes_type
end

#date_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeDate

Date Values of type Date are stored in Value.date_value. Corresponds to the JSON property dateType

Returns:

3633
 
# File 'lib/google/apis/bigtableadmin_v2/classes.rb', line 3631

def date_type
  @date_type
end

#float32_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeFloat32

Float32 Values of type Float32 are stored in Value.float_value. Corresponds to the JSON property float32Type

Returns:



3636
3637
3638
 
# File 'lib/google/apis/bigtableadmin_v2/classes.rb', line 3636

def float32_type
  @float32_type
end

#float64_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeFloat64

Float64 Values of type Float64 are stored in Value.float_value. Corresponds to the JSON property float64Type

Returns:

end

#int64_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeInt64

Int64 Values of type Int64 are stored in Value.int_value. Corresponds to the JSON property int64Type

Returns:



3646
3647
3648
 
# File 'lib/google/apis/bigtableadmin_v2/classes.rb', line 3646

def int64_type
  @int64_type
end

#map_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeMap

A mapping of keys to values of a given type. Values of type Map are stored in a Value.array_value where each entry is another Value.array_value with two elements (the key and the value, in that order). Normally encoded Map values won't have repeated keys, however, clients are expected to handle the case in which they do. If the same key appears multiple times, the last value takes precedence. Corresponds to the JSON property mapType

Returns:

# File 'lib/google/apis/bigtableadmin_v2/classes.rb', line 3656

def map_type
  @map_type

#string_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeString

String Values of type String are stored in Value.string_value. Corresponds to the JSON property stringType

Returns:

# File 'lib/google/apis/bigtableadmin_v2/classes.rb', line 3661

def string_type
  @string_type
end

#struct_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeStruct

A structured data value, consisting of fields which map to dynamically typed values. Values of type Struct are stored in Value.array_value where entries are in the same order and number as field_types. Corresponds to the JSON property structType

Returns:

#timestamp_type ⇒ Google::Apis::BigtableadminV2::GoogleBigtableAdminV2TypeTimestamp

Timestamp Values of type Timestamp are stored in Value.timestamp_value. Corresponds to the JSON property timestampType
