Version 1.7.0 of the Amazon Kinesis Client Library

Release 1.7.0 (August 22, 2016)

• Add support for time based iterators (See GetShardIterator Documentation)
  • PR #94
    The KinesisClientLibConfiguration now supports providing an initial time stamp position.
  • This position is only used if there is no current checkpoint for the shard.
  • This setting cannot be used with DynamoDB Streams
    Resolves Issue #88
• Allow Prioritization of Parent Shards for Task Assignment
  • PR #95
    The KinesisClientLibconfiguration now supports providing a ShardPrioritization strategy. This strategy controls how the Worker determines which ShardConsumer to call next. This can improve processing for streams that split often, such as DynamoDB Streams.
• Remove direct dependency on aws-java-sdk-core, to allow independent versioning.
  • PR #92
    You may need to add a direct dependency on aws-java-sdk-core if other dependencies include an older version.
