public interface MutationApi<T>

The API for creating mutations for a single row.

Type Parameter
Name Description
T

Methods

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

public abstract T 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
T

addToCell(String familyName, ByteString qualifier, long timestamp, long input)

public default T addToCell(String familyName, ByteString qualifier, long timestamp, long input)

Adds an int64 value to an aggregate cell. The column family must be an aggregate family and have an "int64" input type 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 ByteString
timestamp long
input long
Returns
Type Description
T

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

public default T addToCell(String familyName, String qualifier, long timestamp, long value)

Adds an int64 value to an aggregate cell. The column family must be an aggregate family and have an "int64" input type or this mutation will be rejected.

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

qualifier String
timestamp long
value long
Returns
Type Description

Returns
Type Description
T

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

public abstract T 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.

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.

qualifier Value
timestamp Value
input Value
Returns
Type Description
T

mergeToCell(String familyName, ByteString qualifier, long timestamp, ByteString input)

public default T mergeToCell(String familyName, ByteString qualifier, long timestamp, ByteString input)

Merges a ByteString accumulator value to a cell in an aggregate column family.

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
input ByteString
Returns
Type Description
T
