Stream On Demand 5.8.3 ~UPD~ Download Zip

A capacity mode determines how the capacity of a data stream is managed and how you are charged for the usage of your data stream. In Amazon Kinesis Data Streams, you can choose between an on-demand mode and a provisioned mode for your data streams.

On-demand - data streams with an on-demand mode require no capacity planning and automatically scale to handle gigabytes of write and read throughput per minute. With the on-demand mode, Kinesis Data Streams automatically manages the shards in order to provide the necessary throughput.

Provisioned - for the data streams with a provisioned mode, you must specify the number of shards for the data stream. The total capacity of a data stream is the sum of the capacities of its shards. You can increase or decrease the number of shards in a data stream as needed.

You can use Kinesis Data Streams PutRecord and PutRecords APIs to write data into your data streams in both on-demand and provisioned capacity modes. To retrieve data, both capacity modes support default consumers that use the GetRecords API and Enhanced Fan-Out (EFO) consumers that use the SubscribeToShard API.

All Kinesis Data Streams capabilities, including retention mode, encryption, monitoring metrics, and others, are supported for both the on-demand and provisioned modes. Kinesis Data Streams provides the high durability and availability in both the on-demand and provisioned capacity modes.

Data streams in the on-demand mode require no capacity planning and automatically scale to handle gigabytes of write and read throughput per minute. On-demand mode simplifies ingesting and storing large data volumes at a low-latency because it eliminates provisioning and managing servers, storage, or throughput. You can ingest billions of records per day without any operational overhead.

On-demand mode is ideal for addressing the needs of highly variable and unpredictable application traffic. You no longer have to provision these workloads for peak capacity, which can result in higher costs due to low utilization. On-demand mode is suited for workloads with unpredictable and highly-variable traffic patterns.

With the on-demand capacity mode, you pay per GB of data written and read from your data streams. You do not need to specify how much read and write throughput you expect your application to perform. Kinesis Data Streams instantly accommodates your workloads as they ramp up or down. For more information, see Amazon Kinesis Data Streams pricing.

The aggregate read capacity of a data stream with the on-demand mode increases proportionally to write throughput. This helps to ensure that consumer applications always have adequate read throughput to process incoming data in real time. You get at least twice the write throughput compared to read data using the GetRecords API. We recommend that you use one consumer application with the GetRecord API, so that it has enough room to catch up when the application needs to recover from downtime. It is recommended that you use the Enhanced Fan-Out capability of Kinesis Data Streams for scenarios that require adding more than one consumer application. Enhanced Fan-Out supports adding up to 20 consumer applications to a data stream using the SubscribeToShard API, with each consumer application having dedicated throughput.

In the on-demand mode, Kinesis Data Streams splits the shards evenly when it detects an increase in traffic. However, it does not detect and isolate hash keys that are driving a higher portion of incoming traffic to a particular shard. If you are using highly uneven partition keys you may continue to receive write exceptions. For such use cases, we recommend that you use the provisioned capacity mode that supports granular shard splits.

With provisioned mode, after you create the data stream, you can dynamically scale your shard capacity up or down using the AWS Management Console or the UpdateShardCount API. You can make updates while there is a Kinesis Data Streams producer or consumer application writing to or reading data from the stream.

You may still experience read and write throughput exceptions in the provisioned mode if you don't configure your data stream to handle your peak throughput. In this case, you must manually scale your data stream to accommodate your data traffic.

You can switch the capacity mode of your data stream from on-demand to provisioned, or from provisioned to on-demand. For each data stream in your AWS account, you can switch between the on-demand and provisioned capacity modes twice within 24 hours.

Switching between capacity modes of a data stream does not cause any disruptions to your applications that use this data stream. You can continue writing to and reading from this data stream. As you are switching between capacity modes, either from on-demand to provisioned or from provisioned to on-demand, the status of the stream is set to Updating. You must wait for the data stream status to get to Active before you can modify its properties again.

When you switch from provisioned to on-demand capacity mode, your data stream initially retains whatever shard count it had before the transition, and from this point on, Kinesis Data Streams monitors your data traffic and scales the shard count of this on-demand data stream depending on your write throughput.

When you switch from on-demand to provisioned mode, your data stream also initially retains whatever shard count it had before the transition, but from this point on, you are responsible for monitoring and adjusting the shard count of this data stream to properly accomodate your write throughput.

Kinesis Data Streams is a fully-managed, serverless service for real-time processing of streamed data at a massive scale. Kinesis Data Streams can take any amount of data, from any number of sources, and scale up and down as needed. Creating a new data stream is easy, since we announced Kinesis Data Streams in November 2013. To get started, you only need to specify the number of shards with which you must provision your stream.

As customers adopt data streaming broadly, workloads with data traffic that can increase by millions of events in a few minutes are becoming more common. For these volatile traffic patterns, customers carefully plan capacity, monitor throughput, and in some cases develop processes that automatically change the Kinesis Data Streams stream capacity.

Kinesis Data Streams On-Demand Mode

That is why today we are announcing Kinesis Data Streams On-demand. This new capacity mode eliminates the need for provisioning and managing the capacity for streaming data. Using Kinesis Data Streams On-demand automatically scales the capacity in response to varying data traffic. Customers are charged per gigabyte of data written, read, and stored in the stream, in a pay-per-throughput fashion.

Data streams in the on-demand mode have the same high durability, high availability, low latency, security, and deep AWS integrations that Kinesis Data Streams already provides. Moreover, there are no new APIs to write or read data. All existing Kinesis Data Streams integrations work in the on-demand mode.

When a new data stream is created using Kinesis Data Streams On-demand, it gets created with the default capacity of 4 MB/s and 4,000 records per second for writes. Kinesis Data Streams On-demand can automatically scale up to 200 MB/s and 200,000 records per second for writes.

Get Started with Kinesis Data Streams On-demand

Create a new data stream with Kinesis Data Streams On-demand from the AWS console, AWS SDKs, AWS Command Line Interface (AWS CLI), and AWS CloudFormation.

At the time stamp 21:23, we change the stream capacity from provisioned to on-demand. You can do that on-the-fly without affecting the stream. See that it takes a very short time for the stream to handle the load when converting from one capacity mode to the other.

In a few minutes (time stamp 21:24) the throttles start to drop as the stream starts scaling up. The stream capacity doubles to 10 shards first (time stamp 21:26), and the stream keeps scaling up until each shard has a load of less than 0.5 MB/s. In this way, if the stream suddenly receives double the amount of load, then it has the capacity ready to handle it.

Hose stream allowance or demand is the amount of additional water that is added to the sprinkler hydraulic calculation design, when hose connections are added to sprinkler systems. This allowance is not required for most hose connections installed as part of a combined sprinkler-standpipe system using NFPA 14 Standard for the Installation of Standpipe and Hose Systems, designed as a Class I, II or III standpipe system. 2351a5e196
