From 0954ed8b2602df4266378554920f4e65c7390ad0 Mon Sep 17 00:00:00 2001 From: "Pfifer, Justin" Date: Mon, 7 Nov 2016 11:47:47 -0800 Subject: [PATCH] Release 1.7.2 of the Amazon Kinesis Client Library MultiLangDaemon Feature Updates The MultiLangDaemon has been upgraded to use the v2 interfaces, which allows access to enhanced checkpointing, and more information during record processor initialization. The MultiLangDaemon clients must be updated before they can take advantage of these new features. --- META-INF/MANIFEST.MF | 2 +- README.md | 6 +++++- pom.xml | 2 +- 3 files changed, 7 insertions(+), 3 deletions(-) diff --git a/META-INF/MANIFEST.MF b/META-INF/MANIFEST.MF index ab1296f3..2bade10a 100644 --- a/META-INF/MANIFEST.MF +++ b/META-INF/MANIFEST.MF @@ -2,7 +2,7 @@ Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: Amazon Kinesis Client Library for Java Bundle-SymbolicName: com.amazonaws.kinesisclientlibrary;singleton:=true -Bundle-Version: 1.7.1 +Bundle-Version: 1.7.2 Bundle-Vendor: Amazon Technologies, Inc Bundle-RequiredExecutionEnvironment: JavaSE-1.7 Require-Bundle: org.apache.commons.codec;bundle-version="1.6", diff --git a/README.md b/README.md index 4b1e2bbc..893d65fc 100644 --- a/README.md +++ b/README.md @@ -26,9 +26,13 @@ After you've downloaded the code from GitHub, you can build it using Maven. To d For producer-side developers using the **[Kinesis Producer Library (KPL)][kinesis-guide-kpl]**, the KCL integrates without additional effort.  When the KCL retrieves an aggregated Amazon Kinesis record consisting of multiple KPL user records, it will automatically invoke the KPL to extract the individual user records before returning them to the user. ## Amazon KCL support for other languages -To make it easier for developers to write record processors in other languages, we have implemented a Java based daemon, called MultiLangDaemon that does all the heavy lifting. Our approach has the daemon spawn a sub-process, which in turn runs the record processor, which can be written in any language. The MultiLangDaemon process and the record processor sub-process communicate with each other over [STDIN and STDOUT using a defined protocol][multi-lang-protocol]. There will be a one to one correspondence amongst record processors, child processes, and shards. For Python developers specifically, we have abstracted these implementation details away and [expose an interface][kclpy] that enables you to focus on writing record processing logic in Python. This approach enables KCL to be language agnostic, while providing identical features and similar parallel processing model across all languages. +To make it easier for developers to write record processors in other languages, we have implemented a Java based daemon, called MultniLangDaemon that does all the heavy lifting.
