示例1: connect
# 需要导入模块: import contextlib [as 别名]
# 或者: from contextlib import AbstractContextManager [as 别名]
def connect(self) -> contextlib.AbstractContextManager:
"""Context manager to connect to a given database and clean up on exit.
This allows you to pool interactions with the database to prevent possibly
expensive reconnects, or to roll back several interactions if one of them fails.
Note:
Make sure to call :meth:`create` on a fresh database before using this method.
Example:
>>> import terracotta as tc
>>> driver = tc.get_driver('tc.sqlite')
>>> with driver.connect():
... for keys, dataset in datasets.items():
... # connection will be kept open between insert operations
... driver.insert(keys, dataset)
"""
