在BigQuery中,每个项目都有固定的流式表创建速率配额。当创建流式表的请求超过配额限制时,系统会返回“Exceeded rate limits: exceeded quota for Streaming Table Creation Rate in bigquery”错误信息。
要解决这个问题,可以考虑采取以下步骤:
#导入BigQuery库
from google.cloud import bigquery
#设置要修改的配额限制名称和值
quota_name = "streaming-buffer-size"
quota_value = 15 * 1024 * 1024 * 1024
#设置要修改的项目ID
project_id = "your-project-id"
#实例化BigQuery客户端
client = bigquery.Client(project=project_id)
#获取项目的当前配额限制
quotas = client.query(
"""
SELECT *
FROM `project_id.region-bigquery.quotaLimits`
"""
).to_dataframe()
#检查要修改的配额限制是否存在
if quota_name not in quotas["quota_id"].tolist():
print(f"Quota {quota_name} not found.")
#修改配额限制
quota_index = quotas.index[quotas["quota_id"] == quota_name].tolist()[0]
quotas.at[quota_index, "limit"] = str(quota_value)
client.update_table(quotas, "region-bigquery.quotaLimits")
print(f"Updated {quota_name} quota to {quota_value}")
运行这个代码示例将修改配额限制名称为“streaming-buffer-size”的配额限制值(默认限制为10 GB)到15 GB。
