Release 2.0.0 of the Amazon Kinesis Client Library for Node.js

Release 2.0.0 (March 6, 2019)

• Added support for Enhanced Fan-Out.
  Enhanced Fan-Out provides dedicated throughput per stream consumer, and uses an HTTP/2 push API (SubscribeToShard) to deliver records with lower latency.
• Updated the Amazon Kinesis Client Library for Java to version 2.1.2.
  • Version 2.1.2 uses 4 additional Kinesis API's
    WARNING: These additional API's may require updating any explicit IAM policies
    • RegisterStreamConsumer
    • SubscribeToShard
    • DescribeStreamConsumer
    • DescribeStreamSummary
  • For more information about Enhanced Fan-Out with the Amazon Kinesis Client Library please see the announcement and developer documentation.
• Added support for the newer methods to the KCLManager.
  While the original shutdown method will continue to work it's recommended to upgrade to the newer interface.
  • The shutdown has been replaced by leaseLost and shardEnded.
  • Added the leaseLost method which is invoked when a lease is lost.
    leaseLost replaces shutdown where shutdownInput.reason was ZOMBIE.
  • Added the shardEnded method which is invoked when all records from a split or merge have been processed.
    shardEnded replaces shutdown where shutdownInput.reason was TERMINATE.
• Updated the AWS Java SDK version to 2.4.0
• MultiLangDaemon now provides logging using Logback.
  • MultiLangDaemon supports custom configurations for logging via a Logback XML configuration file.
  • The kcl-bootstrap program was been updated to accept either -l or --log-configuration to provide a Logback XML configuration file.
