DynamoDBからkinesis firehose経由でS3に出力

Kinesis Data Streamsの作成

Kinesis Data Firehoseの設定

DynamoDB側の設定

aws dynamodb create-table --table-name 'cities' \
--attribute-definitions '[{"AttributeName":"key","AttributeType": "S"}]' \
--key-schema '[{"AttributeName":"key","KeyType": "HASH"}]' \
--provisioned-throughput '{"ReadCapacityUnits": 5,"WriteCapacityUnits": 5}'

DynamoDB側でデータ生成

aws dynamodb put-item --table-name cities --item '{ "population": { "N": "38164" }, "date_mod": { "S": "1950-6-22" }, "key": { "S": "t0924" }, "name": { "S": "足利" } }'
aws dynamodb put-item --table-name cities --item '{ "population": { "N": "72391" }, "date_mod": { "S": "1950-8-30" }, "key": { "S": "t0925" }, "name": { "S": "日光" } }'
aws dynamodb put-item --table-name cities --item '{ "population": { "N": "56148" }, "date_mod": { "S": "1950-9-7" }, "key": { "S": "t0926" }, "name": { "S": "下野" } }'
