Clickhouse Python/asyncio library for use with SQLAlchemy core
Project description
Clickhouse Python/asyncio library for use with SQLAlchemy core
Example
import aiochsa
import sqlalchemy as sa
table = sa.Table(
'test', sa.MetaData(),
sa.Column('id', sa.Integer),
sa.Column('name', sa.String),
)
async with aiochsa.connect('clickhouse://127.0.0.1:8123') as conn:
await conn.execute(
table.insert(),
[
{'id': 1, 'name': 'Alice'},
{'id': 2, 'name': 'Bob'},
],
)
rows = await conn.fetch(
table.select()
)To add FINAL modifier use with_hint(table, 'FINAL') (see SQLAlchemy docs for details).
Configure logging to show SQL:
logging.getLogger('aiochsa.client.SQL').setLevel(logging.DEBUG)Custom type converters
Here is an example of installing converter for ClickHouse’s DateTime type that requires and returns timezone-aware Python’s datetime object and stores it as UTC:
from datetime import datetime
import aiochsa
from aiochsa.types import DateTimeUTCType, TypeRegistry
types = TypeRegistry()
types.register(DateTimeUTCType, ['DateTime'], datetime)
conn = aiochsa.connect(dsn, types=types)Change log
