**To write multiple records to a stream**

The following ``put-record-batch`` example writes three records to a stream. The data is encoded in Base64 format. ::

    aws firehose put-record-batch \
        --delivery-stream-name my-stream \
        --records file://records.json

Contents of ``myfile.json``::

    [
        {"Data": "Rmlyc3QgdGhpbmc="},
        {"Data": "U2Vjb25kIHRoaW5n"},
        {"Data": "VGhpcmQgdGhpbmc="}
    ]

Output::

    {
        "FailedPutCount": 0,
        "Encrypted": false,
        "RequestResponses": [
            {
