public class JsonStreamWriter implements AutoCloseable

A StreamWriter that can write JSON data (JSONObjects) to BigQuery tables. The JsonStreamWriter is built on top of a StreamWriter, and it simply converts all JSON data to protobuf messages then calls StreamWriter's append() method to write to BigQuery tables.

Static Methods

newBuilder(String streamOrTableName, TableSchema tableSchema) (deprecated)

public static JsonStreamWriter.Builder newBuilder(String streamOrTableName, TableSchema tableSchema)

newBuilder that constructs a JsonStreamWriter builder with BigQuery client being initialized by StreamWriter by default.

Parameters
Name	Description
`streamOrTableName`	`String` name of the stream that must follow "projects/[^/]+/datasets/[^/]+/tables/[^/]+/streams/[^/]+" or table name "projects/[^/]+/datasets/[^/]+/tables/[^/]+"
`tableSchema`	`TableSchema` The schema of the table when the stream was created, which is passed back through `WriteStream`

Returns
Type	Description
`JsonStreamWriter.Builder`	Builder

Methods

append(JSONArray jsonArr) (deprecated)

public ApiFuture<AppendRowsResponse> append(JSONArray jsonArr)

Writes a JSONArray that contains JSONObjects to the BigQuery table by first converting the JSON data to protobuf messages, then using StreamWriter's append() to write the data.

Parameter
Name	Description
`jsonArr`	`org.json.JSONArray` The JSON array that contains JSONObjects to be written

Returns
Type	Description
`ApiFuture<AppendRowsResponse>`	`ApiFuture<AppendRowsResponse>` returns an AppendRowsResponse message wrapped in an ApiFuture

append(JSONArray jsonArr, long offset) (deprecated)

public ApiFuture<AppendRowsResponse> append(JSONArray jsonArr, long offset)

Writes a JSONArray that contains JSONObjects to the BigQuery table by first converting the JSON data to protobuf messages, then using StreamWriter's append() to write the data.

Parameters
Name	Description
`jsonArr`	`org.json.JSONArray` The JSON array that contains JSONObjects to be written
`offset`	`long` Offset for deduplication

Returns
Type	Description
`ApiFuture<AppendRowsResponse>`	`ApiFuture<AppendRowsResponse>` returns an AppendRowsResponse message wrapped in an ApiFuture

close() (deprecated)

public void close()

Closes the underlying StreamWriter.
