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_put_record_batch(DeliveryStreamName, Records)[required] The name of the delivery stream.
[required] One or more records.
svc$put_record_batch(
DeliveryStreamName = "string",
Records = list(
list(
Data = raw
)
)
)
By default, each delivery stream can take in up to 2,000 transactions per second, 5,000 records per second, or 5 MB per second. If you use PutRecord and PutRecordBatch, the limits are an aggregate across these two operations for each delivery stream. For more information about limits, see Amazon Kinesis Data Firehose Limits.
Each PutRecordBatch request supports up to 500 records. Each record in the request can be as large as 1,000 KB (before 64-bit 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.
Kinesis Data 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. Kinesis Data 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, back off and
retry. If the exception persists, it is possible that the throughput
limits have been exceeded for the delivery stream.
Data records sent to Kinesis Data 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.
