About PutRecordBatch¶
Writes multiple data records into a delivery stream in a single call, which can achieve higher throughput per producer than when writing single records. To write single data records into a delivery stream, use PutRecord. Applications using these operations are referred to as producers.
Firehose accumulates and publishes a particular metric for a customer account in one minute intervals. It is possible that the bursts of incoming bytes/records ingested to a delivery stream last only for a few seconds. Due to this, the actual spikes in the traffic might not be fully visible in the customer's 1 minute CloudWatch metrics.
For information about service quota, see Amazon Firehose Quota.
Each PutRecordBatch request supports up to 500 records. Each record in the request can be as large as 1,000 KB (before base64 encoding), up to a limit of 4 MB for the entire request. These limits cannot be changed.
You must specify the name of the delivery stream and the data record when using PutRecord. The data record consists of a data blob that can be up to 1,000 KB in size, and any kind of data. For example, it could be a segment from a log file, geographic location data, website clickstream data, and so on.
Firehose buffers records before delivering them to the destination. To
disambiguate the data blobs at the destination, a common solution is to use delimiters in
the data, such as a newline (\n
) or some other character unique within the
data. This allows the consumer application to parse individual data items when reading the
data from the destination.
The PutRecordBatch response includes a count of failed records,
FailedPutCount
, and an array of responses, RequestResponses
.
Even if the PutRecordBatch call succeeds, the value of
FailedPutCount
may be greater than 0, indicating that there are records for
which the operation didn't succeed. Each entry in the RequestResponses
array
provides additional information about the processed record. It directly correlates with a
record in the request array using the same ordering, from the top to the bottom. The
response array always includes the same number of records as the request array.
RequestResponses
includes both successfully and unsuccessfully processed
records. Firehose tries to process all records in each PutRecordBatch request. A single record failure does not stop the processing
of subsequent records.
A successfully processed record includes a RecordId
value, which is
unique for the record. An unsuccessfully processed record includes ErrorCode
and ErrorMessage
values. ErrorCode
reflects the type of error,
and is one of the following values: ServiceUnavailableException
or
InternalFailure
. ErrorMessage
provides more detailed
information about the error.
If there is an internal server error or a timeout, the write might have completed or
it might have failed. If FailedPutCount
is greater than 0, retry the request,
resending only those records that might have failed processing. This minimizes the possible
duplicate records and also reduces the total bytes sent (and corresponding charges). We
recommend that you handle any duplicates at the destination.
If PutRecordBatch throws ServiceUnavailableException
,
the API is automatically reinvoked (retried) 3 times. If the exception persists, it is
possible that the throughput limits have been exceeded for the delivery stream.
Re-invoking the Put API operations (for example, PutRecord and PutRecordBatch) can result in data duplicates. For larger data assets, allow for a longer time out before retrying Put API operations.
Data records sent to Firehose are stored for 24 hours from the time they are added to a delivery stream as it attempts to send the records to the destination. If the destination is unreachable for more than 24 hours, the data is no longer available.
Don't concatenate two or more base64 strings to form the data fields of your records. Instead, concatenate the raw data, then perform base64 encoding.
