BigQuery BigLake是一个与BigQuery紧密集成的大规模数据存储解决方案,它可以提供更快的大规模数据分析。下面是几个重要的特点:
以下是创建模块并向其写入数据的Python示例:
from google.cloud import bigquery_storage_v1beta1
# TODO(developer): Set the ID of the project that contains the BigQuery dataset.
project_id = 'your-project-id'
# TODO(developer): Set the ID of the BigQuery dataset to write data to.
dataset_id = 'your_dataset_id'
client = bigquery_storage_v1beta1.BigQueryStorageClient()
# Set the table reference
table_ref = client.table_path(project_id, dataset_id, 'your_table_id')
# Set the write stream
stream = client.write_stream(Session(), table_ref)
# Open the stream
stream.open()
# Write rows to the stream
rows = [
("Row 1", 1),
("Row 2", 2),
("Row 3", 3)
]
stream.write_rows(rows)
# Close the stream
stream.close()
以下是使用BigQuery Storage API读取BigLake中的数据的Python示例:
from google.cloud import bigquery_storage_v1beta1
# TODO(developer): Set the ID of the project that contains the BigQuery dataset.
project_id = 'your-project-id'
# TODO(developer): Set the ID of the BigQuery dataset that contains the table to be read.
dataset_id = 'your_dataset_id'
# TODO(developer): Set the ID of the BigQuery table to be read.
table_id =
