Method Details

create

public static RowMutation create(@Nonnull
 String tableId,
 @Nonnull
 String key)

Creates a new instance of the mutation builder.

create

public static RowMutation create(@Nonnull
 String tableId,
 @Nonnull
 com.google.protobuf.ByteString key)

Creates a new instance of the mutation builder.

create

public static RowMutation create(@Nonnull
 String tableId,
 @Nonnull
 String key,
 @Nonnull
 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);
 

create

public static RowMutation create(@Nonnull
 String tableId,
 @Nonnull
 com.google.protobuf.ByteString key,
 @Nonnull
 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);
 

setCell

public RowMutation setCell(@Nonnull
 String familyName,
 @Nonnull
 String qualifier,
 @Nonnull
 String value)

Description copied from interface: MutationApi

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<RowMutation>

setCell

public RowMutation setCell(@Nonnull
 String familyName,
 @Nonnull
 String qualifier,
 long timestamp,
 @Nonnull
 String value)

Description copied from interface: MutationApi

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<RowMutation>

setCell

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

Description copied from interface: MutationApi

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

Uses microseconds since epoch as the timestamp.

Specified by:

setCell in interface MutationApi<RowMutation>

setCell

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

Description copied from interface: MutationApi

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`.

Adds a mutation which deletes cells from the specified column.

Specified by:

toProto

@InternalApi
public MutateRowRequest toProto(com.google.cloud.bigtable.data.v2.internal.RequestContext requestContext)

toBulkProto

@InternalApi
public MutateRowsRequest toBulkProto(com.google.cloud.bigtable.data.v2.internal.RequestContext requestContext)

Creates a single entry bulk MutateRowsRequest, which will be merged by the batching logic in the callable chain.

fromProto

@BetaApi
public static RowMutation fromProto(@Nonnull
 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.
