public final class Mutation implements MutationApi<Mutation>, Serializable

The concrete implementation of MutationApi that can be used to create and represent a list of mutations. It used by RowMutation and ConditionalRowMutation to encapsulate a list of mutations that will to be applied to a single row.

Static Methods

create()

public static Mutation create()

Creates new instance of Mutation object.

Returns

Type	Description
Mutation

createUnsafe()

public static Mutation createUnsafe()

Creates new instance of Mutation object which allows setCell operation to use server side timestamp. This is dangerous because mutations will no longer be idempotent, which might cause multiple duplicate values to be stored in Bigtable. This option should only be used for advanced usecases with extreme care.

Returns

Type	Description
Mutation

fromProtoUnsafe(Iterable<Mutation> protos)

public static Mutation fromProtoUnsafe(Iterable<Mutation> protos)

Wraps the List of protobuf com.google.bigtable.v2.Mutation. This methods, like #createUnsafe(), allows setCell operation to use server side timestamp. This is dangerous because mutations will no longer be idempotent, which might cause multiple duplicate values to be stored in Bigtable. This option should only be used for advanced usecases with extreme care.

Parameter

Name	Description
protos	Iterable<Mutation>

Returns

Type	Description
Mutation

fromProtoUnsafe(List<Mutation> protos)

public static Mutation fromProtoUnsafe(List<Mutation> protos)

Wraps the List of protobuf com.google.bigtable.v2.Mutation. This methods, like #createUnsafe(), allows setCell operation to use server side timestamp. This is dangerous because mutations will no longer be idempotent, which might cause multiple duplicate values to be stored in Bigtable. This option should only be used for advanced usecases with extreme care.

Parameter

Name	Description
protos	List<Mutation>

Returns

Type	Description
Mutation

Methods

deleteCells(String familyName, ByteString qualifier)

public Mutation deleteCells(String familyName, ByteString qualifier)

Adds a mutation which deletes cells from the specified column.

Parameters

Name	Description
familyName	String
qualifier	ByteString

Returns

Type	Description
Mutation

deleteCells(String familyName, ByteString qualifier, Range.TimestampRange timestampRange)

public Mutation deleteCells(String familyName, ByteString qualifier, Range.TimestampRange timestampRange)

Adds a mutation which deletes cells from the specified column, restricted to a given timestamp range.

Parameters

Name	Description
familyName	String
qualifier	ByteString
timestampRange	Range.TimestampRange

Returns

Type	Description
Mutation

deleteCells(String familyName, String qualifier)

public Mutation deleteCells(String familyName, String qualifier)

Adds a mutation which deletes cells from the specified column.

Parameters

Name	Description
familyName	String
qualifier	String

Returns

Type	Description
Mutation

deleteFamily(String familyName)

public Mutation deleteFamily(String familyName)

Adds a mutation which deletes all cells from the specified column family.

Parameter

Name	Description
familyName	String

Returns

Type	Description
Mutation

deleteRow()

public Mutation deleteRow()

Adds a mutation which deletes all cells from the containing row.

Returns

Type	Description
Mutation

setCell(String familyName, ByteString qualifier, ByteString value)

public Mutation setCell(String familyName, ByteString qualifier, ByteString value)

Adds a mutation which sets the value of the specified cell.

Uses microseconds since epoch as the timestamp.

Parameters

Name	Description
familyName	String
qualifier	ByteString
value	ByteString

Returns

Type	Description
Mutation

setCell(String familyName, ByteString qualifier, long value)

public Mutation setCell(String familyName, ByteString qualifier, long value)

Adds a mutation which sets the value of the specified cell.

Uses microseconds since epoch as the timestamp.

Parameters

Name	Description
familyName	String
qualifier	ByteString
value	long

Returns

Type	Description
Mutation

setCell(String familyName, ByteString qualifier, long timestamp, ByteString value)

public Mutation setCell(String familyName, ByteString qualifier, long timestamp, ByteString value)

Adds a mutation which sets the value of the specified cell.

Note: The timestamp values are in microseconds but must match the granularity of the table(defaults to MILLIS). Therefore, the given value must be a multiple of 1000 (millisecond granularity). For example: 1571902339435000.

Parameters

Name	Description
familyName	String
qualifier	ByteString
timestamp	long
value	ByteString

Returns

Type	Description
Mutation

setCell(String familyName, ByteString qualifier, long timestamp, long value)

public Mutation setCell(String familyName, ByteString qualifier, long timestamp, long value)

Adds a mutation which sets the value of the specified cell.

Note: The timestamp values are in microseconds but must match the granularity of the table(defaults to MILLIS). Therefore, the given value must be a multiple of 1000 (millisecond granularity). For example: 1571902339435000.

Parameters

Name	Description
familyName	String
qualifier	ByteString
timestamp	long
value	long

Returns

Type	Description
Mutation

setCell(String familyName, String qualifier, String value)

public Mutation setCell(String familyName, String qualifier, String value)

Adds a mutation which sets the value of the specified cell.

This a convenience method that converts Strings to ByteStrings and uses microseconds since epoch as the timestamp.

Parameters

Name	Description
familyName	String
qualifier	String
value	String

Returns

Type	Description
Mutation

setCell(String familyName, String qualifier, long value)

public Mutation setCell(String familyName, String qualifier, long value)

Adds a mutation which sets the value of the specified cell.

This a convenience method that converts Strings to ByteStrings and uses microseconds since epoch as the timestamp. Also it accepts long value.

Parameters

Name	Description
familyName	String
qualifier	String
value	long

Returns

Type	Description
Mutation

setCell(String familyName, String qualifier, long timestamp, String value)

public Mutation setCell(String familyName, String qualifier, long timestamp, String value)

Adds a mutation which sets the value of the specified cell.

This is a convenience override that converts Strings to ByteStrings.

Note: The timestamp values are in microseconds but must match the granularity of the table(defaults to MILLIS). Therefore, the given value must be a multiple of 1000 (millisecond granularity). For example: 1571902339435000.

Parameters

Name	Description
familyName	String
qualifier	String
timestamp	long
value	String

Returns

Type	Description
Mutation

This is a convenience override that converts Strings to ByteStrings.

Note: The timestamp values are in microseconds but must match the granularity of the table(defaults to MILLIS). Therefore, the given value must be a multiple of 1000 (millisecond granularity). For example: 1571902339435000.

Parameters

Name	Description
familyName	String
qualifier	String
timestamp	long
value	long
