Release 1.8.5 of the Amazon Kinesis Client for Java

Release 1.8.5 (September 26, 2017)

• Only advance the shard iterator for the accepted response.
  This fixes a race condition in the KinesisDataFetcher when it's being used to make asynchronous requests. The shard iterator is now only advanced when the retriever calls DataFetcherResult#accept().

  • Issue #231

Release 1.8.4 of the Amazon Kinesis Client for Java

Release 1.8.4 (September 22, 2017)

• Create a new completion service for each request.
  This ensures that canceled tasks are discarded. This will prevent a cancellation exception causing issues processing records.

Release 1.8.3 of the Amazon Kinesis Client for Java

Release 1.8.3 (September 22, 2017)

• Call shutdown on the retriever when the record processor is being shutdown
  This fixes a bug that could leak threads if using the AsynchronousGetRecordsRetrievalStrategy is being used.
  The asynchronous retriever is only used when KinesisClientLibConfiguration#retryGetRecordsInSeconds, and KinesisClientLibConfiguration#maxGetRecordsThreadPool are set.
  • PR #222

Release 1.8.2 of the Amazon Kinesis Client for Java

Release 1.8.2 (September 20, 2017)

• Add support for two phase checkpoints
  Applications can now set a pending checkpoint, before completing the checkpoint operation. Once the application has completed its checkpoint steps, the final checkpoint will clear the pending checkpoint.
  Should the checkpoint fail the attempted sequence number is provided in the InitializationInput#getPendingCheckpointSequenceNumber otherwise the value will be null.
  • PR #188
• Support timeouts, and retry for GetRecords calls.
  Applications can now set timeouts for GetRecord calls to Kinesis. As part of setting the timeout, the application must also provide a thread pool size for concurrent requests.
  • PR #214
• Notification when the lease table is throttled
  When writes, or reads, to the lease table are throttled a warning will be emitted. If you're seeing this warning you should increase the IOPs for your lease table to prevent processing delays.
  • PR #212
• Support configuring the graceful shutdown timeout for MultiLang Clients
  This adds support for setting the timeout that the Java process will wait for the MutliLang client to complete graceful shutdown. The timeout can be configured by adding shutdownGraceMillis to the properties file set to the number of milliseconds to wait.
  • PR #204

Release 1.8.1 of the Amazon Kinesis Client Library

Release 1.8.1 (August 2, 2017)

• Support timeouts for calls to the MultiLang Daemon
  This adds support for setting a timeout when dispatching records to the client record processor. If the record processor doesn't respond within the timeout the parent Java process will be terminated. This is a temporary fix to handle cases where the KCL becomes blocked while waiting for a client record processor.
  The timeout for the this can be set by adding timeoutInSeconds = <timeout value>. The default for this is no timeout.
  Setting this can cause the KCL to exit suddenly, before using this ensure that you have an automated restart for your application
