1.4.5 SCALABILITY
Growing rate of incoming streaming data is indefinite. Even though the arrival rate of update transactions are not predefined, system processor has to adapt the stream data flow as it grows continuously. Adaptive Stream Query Processor is designed and implemented to execute continuous queries and to adapt indefinite data flow by clustering, proper indexing so as to reduce the storage space and fast retrieval of streaming data.
STREAM PROCESSOR
Streaming processing is the ideal platform to process data streams. Stream processing is designed to analyze and act on real-time streaming data, using continuous queries i.e. SQL-type queries that operate over time and buffer windows. Essential to stream analytics is Stream Processing, or the ability to continuously calculate mathematical or statistical analytics on the fly within the stream. Stream processing solutions are designed to handle high volume in real time with a scalable, highly available and fault tolerant architecture. This enables analysis of data in motion. Finally query processing is used to retrieve useful information from the stream data.
A Stream Query Processor is proposed to achieve fast retrieval of streaming data. Stream Query Processor architecture is represented in Fig. 1.2. volume Figure 1.2 Stream Processor Input data are arriving as stream continuously. The incoming data are time-variant and embedded with timestamp. Hence, timestamp is used as one of the attribute along with
Real-time data warehousing creates some special issues that need to be solved by data warehouse management. These can create issues because of the extensive technicality that is involved for not only planning the system, but also managing problems as they arise. Two aspects of the BI system that need to be organized in order to elude any technical problems are: the architecture design and query workload balancing.
In this article I will show you how Speedment Open Source streams efficiently over standard Java maps, expanding the Stream interface into something called a MapStream! This addition will make it easier to keep your streams concrete and readable even in complex scenarios. Hopefully this will allow you to keep streaming without prematurely collecting the result.
2. Streaming video applications where numerous people want to see the same show at same time, the information is being newly generated in real time
Since, real time processing acts as a game changer in big data the research developed would be to have an insight into real time analytics and streaming data to analyze the flow and to evaluate it using certain tools and techniques.
The Fresh Direct has 300,000-square-foot headquarter and 1,500 employees. 8,500 products and 200,000 customers active in every day transaction. So every second there will be numerous data flowing into the company’s center. But the company lacks of a significant information system to deal with those data. They tried to use technology to convert the data to reports of real time information in order to
The hunger for analyzing data to improve delivered needs and to better meet quality measures is spurring a revolution in all the industries like Healthcare, Manufacturing Industry, Insurance Domain, etc. Considering any Industry, the providers are demanding better respective IT systems that allow Information Management and data analytics professionals to filter through large amounts of data and turn it into "information" that can change the business and function of the industry.
Hadoop is an open source framework that could be very resourceful in data processing of the complex data systems, and has been reverently used in the recent past for query processing in the complex databases that contains millions of records. The major advantage of Hadoop is that it clusters the entire records to few blocks and the query is run on each cluster and the compiled information is displayed in effective terms.
Data warehouses, in contrast, are targeted for decision support. Historical, summarized and consolidated data is more important than detailed, individual records. Since data warehouses contain consolidated data, perhaps from several operational databases, over potentially long periods of time, they tend to be orders of magnitude larger than operational databases; enterprise data warehouses are projected to be hundreds of gigabytes to terabytes in size. The workloads are query intensive with mostly ad hoc, complex queries that can access millions of records and perform a lot of scans, joins, and aggregates. Query throughput and response times are more important than transaction throughput.
For example using Hadoop in the architecture would be able process large data sets and if the query performance is not optimized or if the query is not able to accept the data given, the
In our latest testing we investigated NetApp’s ONTAP data management platform. The storage solution aims to simplify storing and moving data within an
The new system implemented was a very efficient method initially but as time passed and the customer’s database further increased this system started showing problem and thus need is developed to implement
This chapter examines about the real time analytics for different software applications and the current implementation to gather the need. It also constitutes the tabular evaluation between the current implementations.
The volume and density of streaming data have also been rapidly growing. Appropriate indexing approaches are essential to handle fast incoming data and to process continuous flow of queries. A new indexed structure is proposed to reduce the space cost and speed up the retrieval from data storage. ACBSD (Adaptive Clustering Based Stream Data) is proposed to index and retrieve streaming data efficiently. ACBSD-tree is proposed which aims to address the three main challenges in data indexing (1) scalable insert, (2) fast search, and (3) scalable deletion. The tree-based indexing structure requires much less space than linear structure.
With the progress of the enterprise big data project, the importance of data analysis speed is increasingly highlighted. To further enhance the speed of data analysis, IBM unveiled a Hadoop data machine, designed to help enterprise users to meet demands of more variety and more large-scale data (lower cost) real-time analysis.
It is simple and easy to use – the MapReduce model is simple but expressive. With MapReduce,a programmer defines job with only Map and Reduce functions, without
