What is Kinesis client library?
The KCL acts as an intermediary between your record processing logic and Kinesis Data Streams. The KCL performs the following tasks: Connects to the data stream. Enumerates the shards within the data stream. Uses leases to coordinates shard associations with its workers.
Why do we need Kinesis?
You can use Kinesis to ingest everything from videos, IoT telemetry data, application logs, and just about any other data format live. This means you can run various processes and machine learning models on the data live as it flows through your system, instead of having to go to a traditional database first.
How do I stop Kinesis streaming?
Shutting Down an Amazon Kinesis Data Streams Application
When your Amazon Kinesis Data Streams application has completed its intended task, you should shut it down by terminating the EC2 instances on which it is running. You can terminate the instances using the AWS Management Console or the AWS CLI.
Does Netflix use Kinesis?
Netflix Uses Close to 1,000 Amazon Kinesis Shards in Parallel to Process Billions of Traffic Flows. Netflix’s Amazon Kinesis Streams-based solution has proven to be highly scalable, each day processing billions of traffic flows. Typically, about 1,000 Amazon Kinesis shards work in parallel to process the data stream.
Is Kinesis push or pull?
It’s pull. Consumers read from the shards using the KCL via a shard iterator.
When should I use Kinesis?
We recommend Kinesis Data Streams for use cases with requirements that are similar to the following: Routing related records to the same record processor (as in streaming MapReduce). For example, counting and aggregation are simpler when all records for a given key are routed to the same record processor.
What is shard in Kinesis data stream?
A shard has a sequence of data records in a stream. It serves as a base throughput unit of a Kinesis data stream. A shard supports 1 MB/second and 1,000 records per second for writes and 2 MB/second for reads.
What is a lease table?
Lease table – a unique Amazon DynamoDB table that is used to keep track of the shards in a KDS data stream that are being leased and processed by the workers of the KCL consumer application.

What is Kinesi?
Kinesis (biology), a movement or activity of a cell or an organism in response to a stimulus.
In what style you must write Lambda code?
The code must be written in a “stateless” style i.e. it should assume there is no affinity to the underlying compute infrastructure.
Is Facebook using AWS?
Facebook is one of the biggest tech company which is not using AWS or Azure. No cloud for that matter is being used by Facebook to store its data. Facebook is running their own infrastructure to meet their needs, as Facebook had a very large number of users at a point of time when AWS was developing back in 2009.
Why do I need Kinesis?
Kinesis Data Streams is useful for rapidly moving data off data producers and then continuously processing the data, whether that means transforming it before emitting to a data store, running real-time metrics and analytics, or deriving more complex data streams for further processing.
What is a streaming database?
A streaming database is broadly defined as a data store designed to collect, process, and/or enrich an incoming series of data points (i.e., a data stream) in real time, typically immediately after the data is created.
What is sharding in SQL?
Sharding is the process of breaking up large tables into smaller chunks called shards that are spread across multiple servers. A shard is essentially a horizontal data partition that contains a subset of the total data set, and hence is responsible for serving a portion of the overall workload.
