Writes a single data record into an Amazon Firehose delivery stream¶
Description¶
Writes a single data record into an Amazon Firehose delivery stream. To
write multiple data records into a delivery stream, use
put_record_batch. Applications using these operations are referred to
as producers.
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
put_record and put_record_batch, the limits are an aggregate across
these two operations for each delivery stream. For more information
about limits and how to request an increase, see Amazon Firehose
Limits.
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.
You must specify the name of the delivery stream and the data record
when using put_record. The data record consists of a data blob that
can be up to 1,000 KiB in size, and any kind of data. For example, it
can 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 put_record operation returns a RecordId, which is a unique
string assigned to each record. Producer applications can use this ID
for purposes such as auditability and investigation.
If the put_record operation throws a 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 tries 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.
