Class RowMutationEntry

java.lang.Object

com.google.cloud.bigtable.data.v2.models.RowMutationEntry

All Implemented Interfaces:

MutationApi<RowMutationEntry>, Serializable

public class RowMutationEntry
extends Object
implements MutationApi<RowMutationEntry>, Serializable

Represents a list of mutations targeted at a single row. It is meant to be used as an parameter for BigtableDataClient.newBulkMutationBatcher(String).

Note: The changes in the mutation will be applied atomically but the ordering between different RowMutationEntry instances is not guaranteed.

Method Details

create

public static RowMutationEntry create(@Nonnull
 String key)

Creates a new instance of the mutation builder.

create

public static RowMutationEntry create(@Nonnull
 com.google.protobuf.ByteString key)

Creates a new instance of the mutation builder.

createFromMutationUnsafe

@BetaApi
public static RowMutationEntry createFromMutationUnsafe(@Nonnull
 com.google.protobuf.ByteString key,
 @Nonnull
 Mutation mutation)

Creates a new instance from existing mutation.

createUnsafe

@InternalApi("For internal usage only")
public static RowMutationEntry createUnsafe(@Nonnull
 com.google.protobuf.ByteString key)

Creates new instance of mutation builder which allows server timestamp for setCell operations.

NOTE: This functionality is intended for advanced usage.

setCell

public RowMutationEntry setCell(@Nonnull
 String familyName,
 @Nonnull
 String qualifier,
 @Nonnull
 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.

Specified by:

setCell in interface MutationApi<RowMutationEntry>

setCell

public RowMutationEntry setCell(@Nonnull
 String familyName,
 @Nonnull
 String qualifier,
 long timestamp,
 @Nonnull
 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`.

Specified by:

setCell in interface MutationApi<RowMutationEntry>

setCell

public RowMutationEntry setCell(@Nonnull
 String familyName,
 @Nonnull
 com.google.protobuf.ByteString qualifier,
 @Nonnull
 com.google.protobuf.ByteString value)

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

Uses microseconds since epoch as the timestamp.

Specified by:

setCell in interface MutationApi<RowMutationEntry>

setCell

public RowMutationEntry setCell(@Nonnull
 String familyName,
 @Nonnull
 com.google.protobuf.ByteString qualifier,
 long timestamp,
 @Nonnull
 com.google.protobuf.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`.

Specified by:

setCell in interface MutationApi<RowMutationEntry>
