Successfully installed asyncdb

Can also install only drivers required like:

$ pip install asyncdb[pg] # this install only asyncpg

Or install all supported drivers as:

$ pip install asyncdb[all]

Requirements

• Python >= 3.8
• asyncio (https://pypi.python.org/pypi/asyncio/)

Currently AsyncDB supports the following databases:

• PostgreSQL (supporting two different connectors: asyncpg or aiopg)
• SQLite (requires aiosqlite)
• mySQL/MariaDB (requires aiomysql and mysqlclient)
• ODBC (using aioodbc)
• JDBC(using JayDeBeApi and JPype)
• RethinkDB (requires rethinkdb)
• Redis (requires aioredis)
• Memcache (requires aiomcache)
• MS SQL Server (non-asyncio using freeTDS and pymssql)
• Apache Cassandra (requires official cassandra driver)
• InfluxDB (using influxdb)
• CouchBase (using aiocouch)
• MongoDB (using motor and pymongo)
• SQLAlchemy (requires sqlalchemy async (+3.14))
• Oracle (requires oracledb)

Quick Tutorial

from asyncdb import AsyncDB

db = AsyncDB('pg', dsn='postgres://user:password@localhost:5432/database')

# Or you can also passing a dictionary with parameters like:
params = {
    "user": "user",
    "password": "password",
    "host": "localhost",
    "port": "5432",
    "database": "database",
    "DEBUG": True,
}
db = AsyncDB('pg', params=params)

async with await db.connection() as conn:
    result, error = await conn.query('SELECT * FROM test')

And that's it!, we are using the same methods on all drivers, maintaining a consistent interface between all of them, facilitating the re-use of the same code for different databases.

Every Driver has a simple name to call it:

• pg: AsyncPG (PostgreSQL)
• postgres: aiopg (PostgreSQL)
• mysql: aiomysql (mySQL)
• influx: influxdb (InfluxDB)
• redis: redis-py (Redis)
• mcache: aiomcache (Memcache)
• odbc: aiodbc (ODBC)
• oracle: oracle (oracledb)

Output Support

With Output Support results can be returned into a wide-range of variants:

from datamodel import BaseModel

class Point(BaseModel):
    col1: list
    col2: list
    col3: list

db = AsyncDB('pg', dsn='postgres://user:password@localhost:5432/database')
async with await d.connection() as conn:
    # changing output format to Pandas:
    conn.output_format('pandas')  # change output format to pandas
    result, error = await conn.query('SELECT * FROM test')
    conn.output_format('csv')  # change output format to CSV
    result, _ = await conn.query('SELECT TEST')
    conn.output_format('dataclass', model=Point)  # change output format to Dataclass Model
    result, _ = await conn.query('SELECT * FROM test')

Currently AsyncDB supports the following Output Formats:

• CSV (comma-separated or parametrized)
• JSON (using orjson)
• iterable (returns a generator)
• Recordset (Internal meta-Object for list of Records)
• Pandas (a pandas Dataframe)
• Datatable (Dt Dataframe)
• Dataclass (exporting data to a dataclass with -optionally- passing Dataclass instance)
• PySpark Dataframe

And others to come:

• Apache Arrow (using pyarrow)
• Polars (Using Python polars)
• Dask Dataframe
