> 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.
