 ## Introduction
 
-Kinesis is a platform provided by Amazon Web Services (AWS) that enables your application to ingest, buffer, and process data in real-time.
-Kinesis is suitable for applications that require processing and deriving insights from data streams such as logs, metrics, user interactions, and IoT sensor readings.
-Kinesis offers three main services: Kinesis Data Streams, Kinesis Data Firehose, and Kinesis Data Analytics.
-In this page, we take a look at Kinesis Data Streams which allows you to capture and store real-time data streams.
+Kinesis Data Streams is an AWS service for ingesting, buffering, and processing data in high throughput data streams.
+It is used for applications that require real-time processing and deriving insights from data streams such as logs, metrics, user interactions, and sensor readings.
 
-LocalStack allows you to use the Kinesis APIs in your local environment from setting up data streams and configuring data processing to building real-time analytics applications.
-The supported APIs are available on our [API coverage page](https://docs.localstack.cloud/references/coverage/coverage_kinesis/), which provides information on the extent of Kinesis's integration with LocalStack.

 ## Getting started
 
-This guide is designed for users new to Kinesis and assumes basic knowledge of the AWS CLI and our [`awslocal`](https://github.com/localstack/awscli-local) wrapper script.

 | `KINESIS_LATENCY` | Integer value in milliseconds (default: `500`) or `0` (to disable). Particularly useful for testing latency-sensitive applications. Since local Kinesis service lacks latency simulation, you can introduce artificial latency into your AWS calls using this variable. To disable this behavior, set `KINESIS_LATENCY=0`. |
 | `KINESIS_INITIALIZE_STREAMS` | **Deprecated.** Comma-delimited string with stream names, corresponding shard counts, and an optional region for initialization during startup. If no region is provided, the default region is used. For example, `KINESIS_INITIALIZE_STREAMS=my-first-stream:1,my-other-stream:2:us-west-2,my-last-stream:1`. In multi-account setups, the specified streams will be created for all accounts. |
 
+### Native
+
+This provider is implemented purely in Python.
+It can be enabled by setting the configuration option `PROVIDER_OVERRIDE_KINESIS=nextgen`

 ## Resource Browser
 
 The LocalStack Web Application provides a Resource Browser for managing Kinesis Streams & Kafka Clusters.

+- In multi-account setups, each AWS account launches a separate instance of Kinesis Mock, which is very resource intensive when a large number of AWS accounts are used.
