Package Classes (2.26.0)

Summary of entries of Classes for bigquerystorage.

Classes

BigQueryReadClient

Client for interacting with BigQuery Storage API.

The BigQuery storage API can be used to read data stored in BigQuery.

BigQueryWriteClient

BigQuery Write API.

The Write API can be used to write data to BigQuery.

For supplementary information about the Write API, see:

https://cloud.google.com/bigquery/docs/write-api

ReadRowsIterable

An iterable of rows from a read session.

ReadRowsPage

An iterator of rows from a read session message.

ReadRowsStream

A stream of results from a read rows request.

This stream is an iterable of ReadRowsResponse. Iterate over it to fetch all row messages.

If the fastavro library is installed, use the rows() method to parse all messages into a stream of row dictionaries.

If the pandas and fastavro libraries are installed, use the to_dataframe() method to parse all messages into a pandas.DataFrame.

This object should not be created directly, but is returned by other methods in this library.

AppendRowsRequest

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.

MissingValueInterpretation

An enum to indicate how to interpret missing values of fields that are present in user schema but missing in rows. A missing value can represent a NULL or a column default value defined in BigQuery table schema.

MissingValueInterpretationsEntry

ResponseCompressionCodec

Specifies which compression codec to attempt on the entire serialized response payload (either Arrow record batch or Avro rows). This is not to be confused with the Apache Arrow native compression codecs specified in ArrowSerializationOptions. For performance reasons, when creating a read session requesting Arrow responses, setting both native Arrow compression and application-level response compression will not be allowed - choose, at most, one kind of compression.
