            \nQ: How does AWS Lambda process data from Amazon Kinesis streams and Amazon DynamoDB Streams?
            \nAWS Lambda \u5982\u4f55\u5904\u7406\u6765\u81ea\u4e8e Amazon Kinesis \u548c DynamoDB \u7684\u6570\u636e<\/b>\nThe Amazon Kinesis and DynamoDB Streams records sent to your AWS Lambda function are strictly serialized, per shard. This means that if you put two records in the same shard, Lambda guarantees that your Lambda function will be successfully invoked with the first record before it is invoked with the second record. If the invocation for one record times out, is throttled, or encounters any other error, Lambda will retry until it succeeds (or the record reaches its 24-hour expiration) before moving on to the next record. The ordering of records across different shards is not guaranteed, and processing of each shard happens in parallel.\n\u4ece Kinesis \u548c DynamoDB \u5355\u4e2a Shard \u4e0a\u7684\u8bb0\u5f55\u4f1a\u88ab Lambda \u4e25\u683c\u7684\u6309\u5e8f\u5904\u7406\u3002\u8fd9\u610f\u5473\u7740\u5982\u679c\u4f60\u9001\u4e24\u6761\u8bb0\u5f55\u5230\u76f8\u540c\u7684 Shard, Lambda \u5c06\u4f1a\u4fdd\u8bc1\u7b2c\u4e00\u6761\u8bb0\u5f55\u6210\u529f\u5904\u7406\u540e\u624d\u4f1a\u5904\u7406\u7b2c\u4e8c\u6761\u8bb0\u5f55\u3002\u5047\u5982\u5904\u7406\u7b2c\u4e00\u6761\u8bb0\u5f55\u65f6\u8d85\u65f6\uff0c\u6216\u8d85\u8fc7\u8d44\u6e90\u4f7f\u7528\u4e0a\u9650\uff0c\u6216\u78b0\u5230\u4efb\u4f55\u9519\u8bef\uff0c Lambda \u5c06\u4f1a\u4e0d\u65ad\u91cd\u8bd5\u76f4\u5230\u6210\u529f(\u6216\u8bb0\u5f55\u5728 24 \u5c0f\u65f6\u540e\u8fc7\u671f), \u800c\u540e\u624d\u4f1a\u53bb\u5904\u7406\u4e0b\u4e00\u6761\u8bb0\u5f55\u3002\u8de8 Shard \u7684\u8bb0\u5f55\u4e0d\u4fdd\u8bc1\u5230\u8fbe\u987a\u5e8f\uff0c\u4e14\u662f\u5e76\u884c\u5904\u7406\u591a\u4e2a Shard \u6765\u7684\u8bb0\u5f55\u3002\n<\/blockquote>\n\u53ef\u4ee5\u505a\u51e0\u4e2a\u8bd5\u9a8c\uff0c\u4e0b\u9762\u7684\u4ee3\u7801\u53ef\u4ee5\u4fdd\u8bc1\u6d88\u606f\u603b\u662f\u88ab\u53d1\u9001\u5230\u540c\u4e00\u4e2a Kinesis Shard\uff0c\u56e0\u4e3a PartitionKey \u53c2\u6570\u662f\u4e00\u4e2a\u5e38\u91cf"},{"title":"AWS Java Lambda \u4e0e\u73af\u5883\u53d8\u91cf","link":"https:\/\/yanbin.blog\/aws-java-lambda-environment-variable\/","pubDate":"Tue, 28 Mar 2017 00:15:28 -0500","author":"yabqiu@gmail.com (Yanbin Qiu)","guid":"https:\/\/yanbin.blog\/aws-java-lambda-environment-variable\/","description":"\n\u4e00\u53e5\u8bdd\u6982\u8981\uff1a\u5bf9 Lambda \u73af\u5883\u53d8\u91cf\u7684\u4efb\u4f55\u6539\u52a8\u90fd\u4f1a\u5f15\u8d77\u4e00\u6b21 Lambda \u7684\u51b7\u542f\u52a8\uff0c\u5927\u53ef\u653e\u5fc3\u5728 handleRequest(...) \u65b9\u6cd5\u5916\u4f7f\u7528\u73af\u5883\u53d8\u91cf\u3002<\/span><\/p>\n\n\u4ece             AWS \u4e0a Java Lambda \u5e94\u7528\u8bb0\u8981 \u4e2d<\/a>\uff0c\u6211\u5b66\u5230\u4e86 Lambda \u7684\u5b9e\u4f8b\u662f\u8de8\u8bf7\u6c42\u5171\u4eab\u7684\uff0c\u6240\u4ee5\u4e3a\u4f7f\u7528 Lambda \u914d\u7f6e\u7684\u73af\u5883\u53d8\u91cf\u65f6\u66fe\u5199\u51fa\u4e86\u4e0b\u9762\u590d\u6742\u800c\u591a\u4f59<\/strong>\u7684\u00a0 AWS\u00a0 Lambda \u4ee3\u7801:\n
