An experimental wrapper around aiochclient to use it with SQLAlchemy

Project description

An experimental 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()
    )

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)
