如何在BigTable GCP中删除已筛选的行

from google.cloud import bigtable

# 连接到BigTable GCP实例
client = bigtable.Client(project='your-project-id', admin=True)
instance = client.instance('your-instance-id')
table = instance.table('your-table-id')

# 定义筛选条件
filter_condition = bigtable.RowFilterChain(
    filters=[
        bigtable.ColumnQualifierRegexFilter('your-column-qualifier-regex'),
        bigtable.TimestampRangeFilter(start_timestamp=your-start-timestamp, end_timestamp=your-end-timestamp)
    ]
)

# 执行删除操作
rows = table.read_rows(filter_=filter_condition)
for row in rows:
    row.clear()
    row.commit()

print('已删除满足筛选条件的行。')
