aio-aerospike-python 0.0.5

Asyncio wrapper of the Aerospike python client

asyncio wrapper of aerospike python client library

This project is work in progress. please do not use it in production yet.

This project provides a simple way to use aerospike with asyncio.

This project is based on Aerospike python client library docs Docs

installation

pip install aio-aerospike-python

Quick start

start docker compose

docker compose up -d 

from aio_aerospike_python import AioAerospikeClient
import asyncio
config = {
    'hosts': [('0.0.0.0', 3000)]
}
client = AioAerospikeClient(config)
print(client.is_connected())
async def put_some_data(limit:int):
    for i in range(limit):
        key = ("test","test",i)
        data = {"a":i}
        await client.put(key,data)


async def read_data(limit:int):
    for i in range(limit):
        key = ("test","test",i)
        r = await client.get(key)
        print(r)


loop = asyncio.get_event_loop()
loop.run_until_complete(put_some_data(33))
loop.run_until_complete(read_data(33))

client.close()

Now lets test it with concurrency

from aio_aerospike_python import AioAerospikeClient
from aio_aerospike_python import exception
from aerospike_helpers import expressions as exp
import aerospike


import asyncio
config = {
    'hosts': [('0.0.0.0', 3000)]
}

client = AioAerospikeClient(config)
print(client.is_connected())


async def put_some_data(limit: int):
    for i in range(limit):
        key = ("test", "test", i)
        data = {"a": i}
        await client.put(key, data)


async def read_data(limit: int):
    keys = [("test", "test", i) for i in range(limit) ]
    # print(keys)
    r = await client.get_many(keys)
    print(r)


async def use_query(mina: int, maxa: int):
    query = client.query("test", "test")
    expr = expr = exp.And(
        exp.LT(exp.IntBin("a"), maxa),
        exp.GT(exp.IntBin("a"), mina)
    ).compile()
    scan_policy = {"expressions": expr}
    results = await query.results(scan_policy)
    print("query results ===")
    for r in results:
        print(r)


async def use_scan(mina: int, maxa: int):
    scan = client.query("test", "test")
    expr = exp.And(
        exp.LT(exp.IntBin("a"), maxa),
        exp.GT(exp.IntBin("a"), mina)
    ).compile()
    scan_policy = {"expressions": expr}
    results = await scan.results(scan_policy)
    print("scan results ===")
    for r in results:
        print(r)



async def test_append(key=("test","test",3), bin="a", val="test", meta=None, policy=None):
    await client.put(key=key, bins={"vv":"test_"})
    await client.append(key=key, bin="vv", val="append", meta=meta, policy=policy)
    r = await client.get(key=key)
    key, _, bin = r
    print("append")
    print(r)

async def main():
    L = await asyncio.gather(
        put_some_data(700),
        read_data(50),
        use_query(10, 20),
        use_scan(40, 45),
        test_append()
    )

asyncio.run(main())
