<h1 class="topictitle1">What Is DIS?</h1>
<div id="body1493022272989"><p id="dis_01_0001__p5708645417727">Data Ingestion Service (DIS) addresses the challenge of transmitting data from outside the cloud to inside the cloud. DIS builds data intake streams for custom applications capable of processing or analyzing streaming data. DIS continuously captures, transmits, and stores terabytes of data from hundreds of thousands of sources every hour, such as logs, social media feeds, website clickstreams, and location-tracking events.</p>
<div class="section" id="dis_01_0001__section9933162516532"><h4 class="sectiontitle">Data Flows</h4><p id="dis_01_0001__p1548222913560">If you set the dump destination to Object Storage Service (OBS), the streaming data will be dumped to OBS.</p>

<div class="section" id="dis_01_0001__section63248778"><h4 class="sectiontitle">Basic Concepts</h4><ul id="dis_01_0001__ul38841670"><li id="dis_01_0001__li14030717">Stream: A DIS stream is an ordered sequence of data records. Streams are distinguished from each other by the stream names assigned during DIS stream creation. When reading or writing streaming data, you need to specify the name of DIS stream from or to which data will be read or written.</li><li id="dis_01_0001__li1533132951112">Partition: Data records in DIS streams are distributed into partitions. A partition is a base throughput unit of a DIS stream. When creating a DIS stream, you are expected to specify the number of partitions needed within your stream.</li><li id="dis_01_0001__li62746268">Record: A record is a unit of data stored in a DIS stream. A record consists of a serial number, partition key, and data block. Data blocks are important data that your data producer adds to the data stream. The maximum size of a data block (data payload before base64 encoding) is 1 MB.</li><li id="dis_01_0001__li6617653310337">Sequence number: Each data record has a sequence number that is unique within its partition. The sequence number is assigned by DIS when a data producer calls PutRecords to add data to a DIS stream.<p id="dis_01_0001__p3562570110338"><a name="dis_01_0001__li6617653310337"></a><a name="li6617653310337"></a>Sequence numbers for the same partition key generally increase over time; the longer the time period between write requests (PutRecords requests), the larger the sequence numbers become.</p>
</li><li id="dis_01_0001__li3882215410531">DIS application: DIS applications write, read, and process data in DIS streams. You can develop DIS applications using the client library software development kit (SDK).</li><li id="dis_01_0001__li604878981068">SDK: SDK is a Java-based client library. With SDK, you can build DIS applications easily to write, read, and process data in DIS streams.</li><li id="dis_01_0001__li1594842311426">Project: Projects are used to group and isolate OpenStack resources (computing resources, storage resources, and network resources). A project can be a department or a project team. Multiple projects can be created for one tenant account. A region has multiple projects, but one project is related to one region. DIS streams in different projects cannot communicate with each other.</li><li id="dis_01_0001__li2367344406">Checkpoint: When an application consumes data, the latest serial number of the consumed data is recorded as a checkpoint. When the data is reconsumed, the consumption can be continued based on this checkpoint.</li><li id="dis_01_0001__li6731144794017">Application: When multiple applications consume data in the same stream, an APP is used as an identifier to distinguish consumption checkpoints of different applications.</li></ul>

<h1 class="topictitle1">What Can I Do with DIS?</h1>
<div id="body1493022272989"><p id="dis_01_0002__p11139022173023">You can use DIS for rapid data intake from producers and continuous data processing. The following are typical scenarios for using DIS:</p>
<ul id="dis_01_0002__ul25486322172259"><li id="dis_01_0002__li32991673101717">Accelerated log and data feed intake<p id="dis_01_0002__p39436037101722"><a name="dis_01_0002__li32991673101717"></a><a name="li32991673101717"></a>You do not need to batch data on servers before you submit it for intake. Instead, you can have producers push data into streams immediately after data is produced.</p>
<p id="dis_01_0002__p486584101717">For example, system and application logs are pushed as they are streaming in and they will be available for processing in seconds. This prevents the data from being lost if the data producer fails.</p>
</li><li id="dis_01_0002__li53676637101920">Real-time metrics and reporting<p id="dis_01_0002__p59996760101921"><a name="dis_01_0002__li53676637101920"></a><a name="li53676637101920"></a>You can retrieve data from DIS streams for simple data analysis and reporting in real time. For example, your DIS applications can work on metrics and reporting for system and application logs as streaming data is being pushed to DIS streams using application programming interfaces (APIs), rather than wait to receive batches of data.</p>
</li><li id="dis_01_0002__li6747202165836">Real-time data analysis: DIS can be used to analyze real-time data. For example, you can transform data into valuable information and business intelligence by simply putting data into a DIS stream. This can be done in minutes instead of hours or days.</li><li id="dis_01_0002__li23684437102419">Complex stream processing<p id="dis_01_0002__p2915948102420"><a name="dis_01_0002__li23684437102419"></a><a name="li23684437102419"></a>You can create Directed Acyclic Graphs (DAGs) of DIS applications and streams. This typically involves putting data from one or multiple DIS applications into another stream for downstream processing by a different DIS application.</p>

<h1 class="topictitle1">Billing Model</h1>
<div id="body0000001250089797"><p id="dis_01_0223__p1661014503918">Data Ingestion Service (DIS) is charged for resource usage, there are three main billing factors: the duration of Partition and PUT Payload Unit number.</p>
<ul id="dis_01_0223__ul106101503919"><li id="dis_01_0223__li8704120141112">General partition contains duration, PUT Payload Unit number, Data storage size billing factor. Advanced partition contains duration billing factor.</li><li id="dis_01_0223__li443915619103">The duration of Partition: Partition is the base capacity unit of DIS. There are two types of partition: General partition and advanced partition. The general partition provides a capacity of 1MB/sec data input , 2MB/sec data outputand support up to 1000 records put per second. The advanced partition provides a capacity of 5MB/sec data input ,10MB/sec data output and support up to 2000 records put per second .You specify the number of partitions when create the stream based on the throughput requirements. You are charged for each partition at an hourly rate.</li><li id="dis_01_0223__li9610050396">PUT Payload Unit number: A record is the data that your data producer adds to DIS stream. A PUT Payload Unit is counted in 25KB payload "chunks" that comprise a record. For example, a 5KB record contains one PUT Payload Unit, a 45KB record contains two PUT Payload Units, and a 1000KB record contains 40 PUT Payload Units. PUT Payload Unit is charged with a per million PUT Payload Units rate.</li><li id="dis_01_0223__li26111050592">Data storage size: the data storage size in DIS input from the partition. The Customer can specify stream data storage time: from One day to Seven days when create the stream. If the data storage time exceeds the specified time, the data will be automatically aged. In general, the data storage one day is free, it means that 84GB of storage space for each partition is free to use. Of course, the final free space size can be specified according to the actual situation.</li></ul>
<p id="dis_01_0223__p387483571019">DIS is charged for resource usage as follow:</p>
<ul id="dis_01_0223__ul1161515269430"><li id="dis_01_0223__li166152026134320">One Partition Costs = partition time * partition rate + Payload Unit Num * Payload Unit Rate + Data storage size * storage size rate</li><li id="dis_01_0223__li1561562654317">Total Costs per stream = Partition 1 Cost + Partition 2 Cost + … + Partition n Cost</li></ul>
<p id="dis_01_0223__p1917124664313">Both resources will be charged at the same time. Each charged will be listed separately. There will be 3 CDR records for each stream in the billing interval.</p>
<p id="dis_01_0223__p9172194617438">The data will be cached for some time in the service, and default cache time is 24 hours. If the user want dump the data to OBS, the operation in OBS will be charged separately.</p>
<p id="dis_01_0223__p773845944514">Example:</p>
<p id="dis_01_0223__p1584071224616">Let us assume that our data producers put 50 records per second in aggregate, and each record is 35KB. In this case, the total data input rate is 1.7MB/sec (50 records/sec*35KB/record). For simplicity, we assume that the throughput and data size of each record are stable and constant throughout the day.</p>
<p id="dis_01_0223__p3840712104614">We first calculate the number of partitions needed for our stream to achieve the required throughput. As one partition provides a capacity of 1MB/sec data input and supports 1000 records/sec, two partitions provide a capacity of 2MB/sec data input and support 2000 records/sec. So a stream with two partitions satisfies our required throughput of 1.7MB/sec at 50 records/sec.</p>
<p id="dis_01_0223__p18840131220468">We then calculate our costs using DIS pricing:</p>

For example, a 5KB record contains one PUT Payload Unit, a 45KB record contains two PUT Payload Units, and a 1MB record contains 40 PUT Payload Units. PUT Payload Unit is charged with a per million PUT Payload Units rate.</p>
