Subject [jira] [Commented] (FLINK-7366) Upgrade kinesis producer library, kinesis client library, and AWS SDK in flink-connector-kinesis

    [ https://issues.apache.org/jira/browse/FLINK-7366?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16123167#comment-16123167

ASF GitHub Bot commented on FLINK-7366:

Github user tzulitai commented on the issue:

    Ok, so it seems like Java serialization of the Kinesis classes was removed only starting
from 1.3.x.
    That means unless we do some classloading trick, we can't really upgrade the Kinesis consumer
dependencies until 1.2 savepoint compatibility is no longer supported.

>                 URL: https://issues.apache.org/jira/browse/FLINK-7366
>             Project: Flink
>          Issue Type: Bug
>          Components: Kinesis Connector
>    Affects Versions: 1.3.2
>            Reporter: Bowen Li
>            Assignee: Bowen Li
>             Fix For: 1.4.0, 1.3.3
> We need to upgrade KPL and KCL to pick up the enhanced performance and stability for
Flink to work better  with Kinesis. Upgrading KPL is specially necessary, because the KPL
version Flink uses is old, and doesn't have good retry and error handling logic.
> *KPL:*
> flink-connector-kinesis currently uses kinesis-producer-library 0.10.2, which is released
in Nov 2015 by AWS. It's old. It's the fourth release, and thus problematic. It doesn't even
have good retry logic, therefore Flink fails really frequently (about every 10 mins as we
observed) when Flink writes too fast to Kinesis and receives RateLimitExceededException, 
> Quotes from https://github.com/awslabs/amazon-kinesis-producer/issues/56, "*With the
newer version of the KPL it uses the AWS C++ SDK which should offer additional retries.*"
on Oct 2016. 0.12.5, the version we are upgrading to, is released in May 2017 and should have
the enhanced retry logic.
> *KCL:*
> Upgrade KCL from 1.6.2 to 1.8.1
> from 1.10.71 to 1.11.171
