PutRecord 搭配 a AWS SDK 或 CLI 使用

將記錄寫入串流

下列put-record範例會將資料寫入串流。資料以 Base64 格式編碼。

aws firehose put-record \
    --delivery-stream-name my-stream \
    --record '{"Data":"SGVsbG8gd29ybGQ="}'

輸出：

{
    "RecordId": "RjB5K/nnoGFHqwTsZlNd/TTqvjE8V5dsyXZTQn2JXrdpMTOwssyEb6nfC8fwf1whhwnItt4mvrn+gsqeK5jB7QjuLg283+Ps4Sz/j1Xujv31iDhnPdaLw4BOyM9Amv7PcCuB2079RuM0NhoakbyUymlwY8yt20G8X2420wu1jlFafhci4erAt7QhDEvpwuK8N1uOQ1EuaKZWxQHDzcG6tk1E49IPeD9k",
    "Encrypted": false
}
