>             Project: Flink
>          Issue Type: Improvement
>          Components: Kinesis Connector
>    Affects Versions: 1.3.0
>            Reporter: Bowen Li

>            Priority: Minor
>             Fix For: 1.4.0

> Background: {{DEFAULT_SHARD_DISCOVERY_INTERVAL_MILLIS}} in 
> {{org.apache.flink.streaming.connectors.kinesis.config.ConsumerConfigConstants}}
>  is the default value for Flink to call Kinesis's {{describeStream()}} API.
> Problem: Right now, its value is 10,000millis (10sec), which is too short. We 
> ran into problems that Flink-kinesis-connector's call of {{describeStream()}} 
> exceeds Kinesis rate limit, and broken Flink taskmanager.
> According to 
> http://docs.aws.amazon.com/kinesis/latest/APIReference/API_DescribeStream.html,
>  
> "This operation has a limit of 10 transactions per second per account.". What 
> it means is that the 10transaction/account is a limit on a single 
> organization's AWS account......:(  We contacted AWS Support, and confirmed 
> this. If you have more applications (either other Flink apps or non-Flink 
> apps) competing aggressively with your Flink app on this API, your Flink app 
> breaks. 
> I propose increasing the value DEFAULT_SHARD_DISCOVERY_INTERVAL_MILLIS from 
> 10,000millis(10sec) to preferably 300,000 (5min). Or at least 60,000 (1min) 
> if anyone has a solid reason arguing that 5min is too long, 
> This is also related to https://issues.apache.org/jira/browse/FLINK-6365
