Description:

asyncrepool 1.0.1

async-repool is a Python library which provides a asyncio-based connection pool management for accessing a RethinkDB database. async-repool creates and maintains a configurable pool of active connection to a RethinkDB database. These connections are then available individually through a basic API.
Internally, repool uses the Python AsyncIO Queue class which is not thread-safe. This means that the same connection pool cannot be share between several threads, please, use asyncio with process workers instead.
This is just asyncio-based clone of repool.

Installation
async-repool is available as a python library on Pypi. Installation is very simple using pip :
$ pip install async_repool
This will install async-repool as well as rethinkdb dependency.


Basic usage
A new connection pool using default connection configurations can simply be created by:
from async_repool import AsyncConnectionPool

pool = AsyncConnectionPool(dict()) # Required argument is kwargs for R.connect function
await pool.init_pool()
conn = await pool.acquire() #returns a Connection instance
await r.table('heroes').run(conn) #do RethinkDB stuff
# ...
pool.release(conn) #put back connection to the pool
await pool.release_pool() #release pool (close rethinkdb connections)

# ...
async with pool.connect() as conn1:
# do something with conn1
# pool.release(conn1) is automatically called after leaving the with code block


Optional arguments
AsyncConnectionPool creation accepts a number of optional arguments:

pool_size: set the pool size, ie. the number of connections opened simultaneously (default=3).
connection_ttl: set the connection time to live. Connections older than TTL are automatically closed and re-opened when acquire (default=3600 seconds, set to 0 for disable)
