Static Methods

create(TargetId targetId, ByteString key)

public static RowMutation create(TargetId targetId, ByteString key)

Creates a new instance of the mutation builder for the given target with targetId. See Also: TableId, AuthorizedViewId

Parameters
Name Description
targetId TargetId
key ByteString
Returns
Type Description
RowMutation

create(TargetId targetId, ByteString key, Mutation mutation)

public static RowMutation create(TargetId targetId, ByteString key, Mutation mutation)

Creates new instance of mutation builder for the given target with targetId 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(TableId.of("[TABLE]"), [BYTE_STRING_ROW_KEY], mutation);

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

addToCell(String familyName, Value qualifier, Value timestamp, Value input)

public RowMutation addToCell(String familyName, Value qualifier, Value timestamp, Value input)

Adds a Value to an aggregate cell. The column family must be an aggregate family and have an input type matching the type of Value or this mutation will be rejected.

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 Value
timestamp Value
input Value
Returns
Type Description
RowMutation

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)

mergeToCell(String familyName, Value qualifier, Value timestamp, Value input)

public RowMutation mergeToCell(String familyName, Value qualifier, Value timestamp, Value input)

Merges a Value accumulator to an aggregate cell. The column family must be an aggregate family or this mutation will be rejected.
