Static Methods

create(String tableId, ByteString key)

public static RowMutation create(String tableId, ByteString key)

Creates a new instance of the mutation builder.

Parameters
Name	Description
tableId	String
key	ByteString

Returns
Type	Description
RowMutation

create(String tableId, ByteString key, Mutation mutation)

public static RowMutation create(String tableId, ByteString key, Mutation mutation)

Creates new instance of mutation builder by wrapping existing set of row mutations. The builder will be owned by this RowMutation and should not be used by the caller after this call. This functionality is intended for advanced usage.

Sample code:

 Mutation mutation = Mutation.create()
     .setCell("[FAMILY_NAME]", "[QUALIFIER]", [TIMESTAMP], "[VALUE]");
 RowMutation rowMutation = RowMutation.create("[TABLE]", [BYTE_STRING_ROW_KEY], mutation);
 

Parameters
Name	Description
tableId	String
key	ByteString
mutation	Mutation

Returns
Type	Description
RowMutation

create(String tableId, String key)

public static RowMutation create(String tableId, String key)

Creates a new instance of the mutation builder.

Parameters
Name	Description
tableId	String
key	String

Returns
Type	Description
RowMutation

create(String tableId, String key, Mutation mutation)

public static RowMutation create(String tableId, String key, Mutation mutation)

Creates new instance of mutation builder by wrapping existing set of row mutations. The builder will be owned by this RowMutation and should not be used by the caller after this call. This functionality is intended for advanced usage.

Sample code:

 Mutation mutation = Mutation.create()
     .setCell("[FAMILY_NAME]", "[QUALIFIER]", [TIMESTAMP], "[VALUE]");
 RowMutation rowMutation = RowMutation.create("[TABLE]", "[ROW_KEY]", mutation);
 

Parameters
Name	Description
tableId	String
key	String
mutation	Mutation

Returns
Type	Description
RowMutation

fromProto(MutateRowRequest request)

public static RowMutation fromProto(MutateRowRequest request)

Wraps the protobuf MutateRowRequest.

This is meant for advanced usage only. Please ensure that the MutateRowRequest does not use server side timestamps. The BigtableDataClient assumes that RowMutations are idempotent and is configured to enable retries by default. If serverside timestamps are enabled, this can lead to duplicate mutations.

WARNING: when applied, the resulting mutation object will ignore the project id and instance id in the table_name and instead apply the configuration in the client.

Parameter
Name	Description
request	com.google.bigtable.v2.MutateRowRequest

Returns
Type	Description
RowMutation

Methods

deleteCells(String familyName, ByteString qualifier)

public RowMutation 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
RowMutation

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

public RowMutation 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
RowMutation

deleteCells(String familyName, String qualifier)

public RowMutation 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
RowMutation

deleteFamily(String familyName)

public RowMutation deleteFamily(String familyName)

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

Parameter
Name	Description
familyName	String

Returns
Type	Description
RowMutation

deleteRow()

public RowMutation deleteRow()

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

Returns
Type	Description
RowMutation

setCell(String familyName, ByteString qualifier, ByteString value)

public RowMutation 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
RowMutation

setCell(String familyName, ByteString qualifier, long value)

public RowMutation 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
RowMutation

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

public RowMutation 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
RowMutation

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

public RowMutation 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
RowMutation
