Class AppendRowsRequest (3.4.0)

public final class AppendRowsRequest extends GeneratedMessageV3 implements AppendRowsRequestOrBuilder

Request message for AppendRows.

Because AppendRows is a bidirectional streaming RPC, certain parts of the AppendRowsRequest need only be specified for the first request before switching table destinations. You can also switch table destinations within the same connection for the default stream.

The size of a single AppendRowsRequest must be less than 10 MB in size. Requests larger than this return an error, typically INVALID_ARGUMENT.

Methods

containsMissingValueInterpretations(String key)

public boolean containsMissingValueInterpretations(String key)

A map to indicate how to interpret missing value for some fields. Missing values are fields present in user schema but missing in rows. The key is the field name. The value is the interpretation of missing values for the field.

For example, a map {'foo': NULL_VALUE, 'bar': DEFAULT_VALUE} means all missing values in field foo are interpreted as NULL, all missing values in field bar are interpreted as the default value of field bar in table schema.

If a field is not in this map and has missing values, the missing values in this field are interpreted as NULL.

This field only applies to the current request, it won't affect other requests on the connection.

Currently, field name can only be top-level column name, can't be a struct field path like 'foo.bar'.

getDefaultMissingValueInterpretation()

public AppendRowsRequest.MissingValueInterpretation getDefaultMissingValueInterpretation()

Optional. Default missing value interpretation for all columns in the table. When a value is specified on an AppendRowsRequest, it is applied to all requests on the connection from that point forward, until a subsequent AppendRowsRequest sets it to a different value. missing_value_interpretation can override default_missing_value_interpretation. For example, if you want to write NULL instead of using default values for some columns, you can set default_missing_value_interpretation to DEFAULT_VALUE and at the same time, set missing_value_interpretations to NULL_VALUE on those columns.

.google.cloud.bigquery.storage.v1.AppendRowsRequest.MissingValueInterpretation default_missing_value_interpretation = 8 [(.google.api.field_behavior) = OPTIONAL];

Returns
TypeDescription
AppendRowsRequest.MissingValueInterpretation

The defaultMissingValueInterpretation.

getWriteStream()

public String getWriteStream()

Required. The write_stream identifies the append operation. It must be provided in the following scenarios:

  • In the first request to an AppendRows connection.

  • In all subsequent requests to an AppendRows connection, if you use the same connection to write to multiple tables or change the input schema for default streams.

    For explicitly created write streams, the format is:

  • projects/{project}/datasets/{dataset}/tables/{table}/streams/{id}

    For the special default stream, the format is:

  • projects/{project}/datasets/{dataset}/tables/{table}/streams/_default.

    An example of a possible sequence of requests with write_stream fields within a single connection:

  • r1: {write_stream: stream_name_1}

  • r2: {write_stream: /*omit*/}

  • r3: {write_stream: /*omit*/}

  • r4: {write_stream: stream_name_2}

  • r5: {write_stream: stream_name_2}

    The destination changed in request_4, so the write_stream field must be populated in all subsequent requests in this stream.

string write_stream = 1 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

Returns
TypeDescription
String

The writeStream.

getWriteStreamBytes()

public ByteString getWriteStreamBytes()

Required. The write_stream identifies the append operation. It must be provided in the following scenarios:

  • In the first request to an AppendRows connection.

  • In all subsequent requests to an AppendRows connection, if you use the same connection to write to multiple tables or change the input schema for default streams.

    For explicitly created write streams, the format is:

  • projects/{project}/datasets/{dataset}/tables/{table}/streams/{id}

    For the special default stream, the format is:

  • projects/{project}/datasets/{dataset}/tables/{table}/streams/_default.

    An example of a possible sequence of requests with write_stream fields within a single connection:

  • r1: {write_stream: stream_name_1}

  • r2: {write_stream: /*omit*/}

  • r3: {write_stream: /*omit*/}

  • r4: {write_stream: stream_name_2}

  • r5: {write_stream: stream_name_2}

    The destination changed in request_4, so the write_stream field must be populated in all subsequent requests in this stream.

string write_stream = 1 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

Returns
TypeDescription
ByteString

The bytes for writeStream.

hasOffset()

public boolean hasOffset()

If present, the write is only performed if the next append offset is same as the provided value. If not present, the write is performed at the current end of stream. Specifying a value for this field is not allowed when calling AppendRows for the '_default' stream.

.google.protobuf.Int64Value offset = 2;

Returns
TypeDescription
boolean
