* Added support for Enhanced Fan Out.
Enhanced Fan Out provides for lower end to end latency, and increased number of consumers per stream.
* Records are now delivered via streaming, reducing end-to-end latency.
* The Amazon Kinesis Client will automatically register a new consumer if required.
When registering a new consumer, the Kinesis Client will default to the application name unless configured otherwise.
* New configuration options are available to configure Enhanced Fan Out.
* `SubscribeToShard` maintains long lived connections with Kinesis, which in the AWS Java SDK 2.0 is limited by default.
The `KinesisClientUtil` has been added to assist configuring the `maxConcurrency` of the `KinesisAsyncClient`.
__WARNING: The Amazon Kinesis Client may see significantly increased latency, unless the `KinesisAsyncClient` is configured to have a `maxConcurrency` high enough to allow all leases plus additional usages of the `KinesisAsyncClient`.__
| Name | Default | Description |
|-----------------|---------|---------------------------------------------------------------------------------------------------------------------|
| consumerArn | Unset | The ARN for an already created consumer. If this is set, the Kinesis Client will not attempt to create a consumer. |
| streamName | Unset | The name of the stream that a consumer should be create for if necessary |
| consumerName | Unset | The name of the consumer to create. If this is not set the applicationName will be used instead. |
| applicationName | Unset | The name of the application. This is used as the name of the consumer unless consumerName is set. |
* Modular Configuration of the Kinesis Client
The Kinesis Client has migrated to a modular configuration system, and the `KinesisClientLibConfiguration` class has been removed.
Configuration has been split into 7 classes. Default versions of the configuration can be created from the `ConfigsBuilder`.
Please see the migration guide for more information
* `CheckpointConfig`
* `CoordinatorConfig`
* `LeaseManagementConfig`
* `LifecycleConfig`
* `MetricsConfig`
* `ProcessorConfig`
* `RetrievalConfig`
* Upgraded to AWS Java SDK 2.0
The Kinesis Client now uses the AWS Java SDK 2.0. The dependency on AWS Java SDK 1.11 has been removed.
All configurations will only accept 2.0 clients.
* When configuring the `KinesisAsyncClient` the `KinesisClientUtil#createKinesisAsyncClient` can be used to configure the Kinesis Client
* __If you need support for AWS Java SDK 1.11 you will need to add a direct dependency.__
__When adding a dependency you must ensure that the 1.11 versions of Jackson dependencies are excluded__
Please see the migration guide for more information
* MultiLangDaemon is now a separate module
The MultiLangDaemon has been separated to its own Maven module and is no longer available in `amazon-kinesis-client`. To include the MultiLangDaemon, add a dependency on `amazon-kinesis-client-multilang`.
* Release 1.9.1 of the Amazon Kinesis Client Library for Java
Updated versions, and added release notes.
* Added note about the update of the AWS Java SDK
* Add a warning about ListShards and IAM Polices
* Corrected some spelling errors
* Add the same warning to the changelog
Added the warning from the README.md to the CHANGELOG.md.
* Added support for ListShards API. This API is used in place of DescribeStream API to provide more throughput during ShardSyncTask.
* ListShards supoorts higher call rate, which should reduce instances of throttling when attempting to synchronize the shard list.
* Updated the version of AWS Java SDK to 1.11.272.
* Version 1.11.272 is now the minimum support versiojn of the SDK.
* Deprecated the following methods, and classes. These methods, and classes will be removed in a future release.
* Deprecated IKinesisProxy#getStreamInfo.
* Deprecated IKinesisProxyFactory.
* Deprecated KinesisProxyFactory.
* Deprecated certain KinesisProxy constructors.
