A. B. C. D. E.Answer: B, C, E.
Option A is incorrect -This is different from Kinesis Data stream record.
KPL user record is a blob of data that has particular meaning to the user.
Examples include a JSON blob representing a UI event on a website, or a log entry from a web server.
https://docs.aws.amazon.com/streams/latest/dev/kinesis-kpl-concepts.htmlOption B is correct - A Kinesis Data Streams record is an instance of the Record data structure defined by the Kinesis Data Streams service API.
Kinesis Data Streams record contains a partition key, sequence number, and a blob of data.
https://docs.aws.amazon.com/streams/latest/dev/kinesis-kpl-concepts.htmlOption C is correct -Kinesis Data Streams record is an instance of the Record data structure defined by the Kinesis Data Streams service API.
Kinesis Data Streams record contains a partition key, sequence number, and a blob of data.
https://docs.aws.amazon.com/streams/latest/dev/kinesis-kpl-concepts.htmlOption D is incorrect - KPL user record and Kinesis Data stream record are different.
https://docs.aws.amazon.com/streams/latest/dev/kinesis-kpl-concepts.htmlOption E is correct -KPL user record and Kinesis Data stream record are different.
https://docs.aws.amazon.com/streams/latest/dev/kinesis-kpl-concepts.htmlKinesis Data Streams is a managed service offered by Amazon Web Services (AWS) that allows users to process and analyze streaming data in real-time. Kinesis Data Streams allows users to capture, process, and store data from sources such as website clickstreams, IoT devices, social media, and more.
A Kinesis Data Streams record is a unit of data that is processed by the service. The record consists of three parts: a partition key, a sequence number, and a data blob. The partition key is used to determine which shard in the Kinesis Data Stream the record should be written to, while the sequence number is a unique identifier for the record within the shard. The data blob is the actual payload of the record, which can be up to 1MB in size.
In the case of Tick-Bank, the Kinesis Producer Library (KPL) is being used to process data into a stream and Kinesis Client Library (KCL) is being used to collect the data. The KPL user record and Kinesis Data Stream record are not the same. The KPL user record is the data being processed by the KPL and is typically a small amount of data, such as tens of bytes per click. The Kinesis Data Stream record is the record that is written to the Kinesis Data Stream and includes the partition key, sequence number, and data blob.
Therefore, the correct options are:
A. Kinesis Data Stream record is a blob of data that has particular meaning to the user. Examples include a JSON blob representing a UI event on a website, or a log entry from a web server. B. A Kinesis Data Streams record is an instance of the Record data structure defined by the Kinesis Data Streams service API. C. Kinesis Data Streams record contains a partition key, sequence number, and a blob of data.
Option D is incorrect because KPL user record and Kinesis Data Stream record are not the same, and option E is incorrect because KPL user record and Kinesis Data Stream record are different.
