Producer for AWS Kinesis Stream with record aggregation

Project description

Python producer for AWS Kinesis Stream with record aggregation.

It uses Boto 3 and is tested on Python 2.7 and 3.4/3.5.

Install

pip install ‘kinesis_producer < 1’

Note: Kinesis Producer use semver: you should always freeze on the major version since it could mean breaking the API.

Usage

Send records aggregated up to 100KB, 200ms and joined with ‘\n’:

from kinesis_producer import KinesisProducer

config = dict(
    aws_region='us-east-1',
    buffer_size_limit=100000,
    buffer_time_limit=0.2,
    kinesis_concurrency=1,
    kinesis_max_retries=10,
    record_delimiter='\n',
    stream_name='KINESIS_STREAM_NAME',
    )

k = KinesisProducer(config=config)

for record in records:
    k.send(record)

k.close()
k.join()

Config

aws_region:AWS region for Kinesis calls (like us-east-1)
buffer_size_limit:
 Approximative size limit for record aggregation (in bytes)
buffer_time_limit:
 Approximative time limit for record aggregation (in seconds)
kinesis_concurrency:
 Set the concurrency level for Kinesis calls. Set to 1 for no concurrency. Set to 2 and more to use a thread pool.
kinesis_max_retries:
 Number of Kinesis put_records call attempt before giving up. This number should be between 4 and 10 if you want to handle temporary ProvisionedThroughputExceeded errors.
record_delimiter:
 Delimiter for record aggregation
stream_name:Name of the Kinesis Stream

Kinesis retries

Kinesis calls are retried for ProvisionedThroughputExceeded error only. Retry use an exponential backoff logic (0.1s, 0.2s, 0.4s, 0.8s, 1.60s, 3.20s, 6.40s, 12.80s, 25.60s, 51.20s, 102.40s…)
