Bowen Li updated FLINK-7508:
----------------------------
Priority: Critical (was: Major)
> switch FlinkKinesisProducer to use KPL's ThreadingMode to ThreadedPool mode
> rather than Per_Request mode
> --------------------------------------------------------------------------------------------------------
>
> Key: FLINK-7508
> URL: https://issues.apache.org/jira/browse/FLINK-7508
> Project: Flink
> Issue Type: Improvement
> Components: Kinesis Connector
> Affects Versions: 1.3.0
> Reporter: Bowen Li
> Assignee: Bowen Li
> Priority: Critical
> Fix For: 1.4.0, 1.3.3
>
>
> KinesisProducerLibrary (KPL) 0.10.x had been using a
> One-New-Thread-Per-Request model for all requests sent to AWS Kinesis, which
> is very expensive.
> 0.12.4 introduced a new [ThreadingMode -
> Pooled|https://github.com/awslabs/amazon-kinesis-producer/blob/master/java/amazon-kinesis-producer/src/main/java/com/amazonaws/services/kinesis/producer/KinesisProducerConfiguration.java#L225],
> which will use a thread pool. This hugely improves KPL's performance and
> reduces consumed resources. By default, KPL still uses per-request mode. We
> should explicitly switch FlinkKinesisProducer's KPL threading mode to
> 'Pooled'.
> This work depends on FLINK-7366 which upgrades KPL from 0.10 to 0.12.5.
