Research and Thesis Topics in Data Stream Processing

Data Streaming plays a major role in real-time applications due to the generation of data from an infinite number of sources, and stream processing produces responses much faster than the other data processing methods.A data stream is a continuous flow of data from heterogeneous sources. Examples include activity stream data from a web or mobile application, time-stamped log data, transactional data, and event streams from sensor or device networks.

Stream processing in data management is needed because it accelerates decision-making and develops the adaptive application. Stream processing refers to the processing of a continuous stream of data instantly as it is produced. It analyzes streaming data in real time and is used when the data size is unknown, infinite, and continuous. Machine learning at vast amounts of data or process stream data has three potential levels of impact: reducing the number of incoming data points or dimensions, data handling process, and implementation and modification of learning algorithm.

  • In real-time, data arrives continuously in a potentially infinite stream in a time-varying, unpredictable, rapid, heterogeneous, continuous, and unbound nature. Datastream processing systems normally hold fixed storage and computing power and process data streams by a resource-constrained system.
  • Nowadays, data stream processing is inevitable. Several business services use streaming technologies and show astonishing results.
  • When the stream data arrives from different sources, making sense of such incoming massive stream data and the historical data present is the main challenge.
  • In contrast to conventional data mining algorithms, mining or analyzing continuously arriving stream data raises numerous challenges.
  • In real-stream learning tasks is that data typically changes over time. Hence, adaptive machine-learning models are needed to handle concept drift.
  • The effective use of entire information from the vast stream data is still a bottleneck in stream data processing.
  • It is necessary to work on data stream extraction and loading according to the requirements of the data stream processor and requires a solution for integrating the data from both operational data sources and data stream applications.

  • The Architecture of Data Stream Processing

    The typical data streaming architectures contain the following components:
    Message Broker: The message broker takes the data from the source and converts it into a standard message format. It then streams the messages continuously, making them available for consumption by the destination. The message broker acts as a buffer, ensuring a smooth data flow between producers and consumers, even if they operate at different speeds.
    Data Streaming Storage: Businesses often store their streaming data in data lakes such as Azure Data Lake Store (ADLS) or Google Cloud Storage. Managing the data streaming storage can be challenging as it involves data partitioning, processing, and backfilling with historical data. Data lakes provide a scalable and cost-effective solution for storing and managing large volumes of streaming data.
    Analytical Tools: After the processing tools process the data, analytical tools come into play. These tools help analyze the data to extract valuable insights and provide business value. They enable tasks such as data exploration, visualization, and advanced analytics on the streaming data.
    Processing Tools: Once the messages are received from the message broker, processing tools like Storm, Apache Spark Streaming, and Apache Flink are used to manipulate further and process the data. These tools enable tasks such as data transformations, aggregations, and calculations on the streaming data.

    Organizations can efficiently process, analyze, and store streaming data by leveraging these components in a data-streaming architecture, enabling real-time insights and decision-making.

    Why do we need a Data Stream Processing Architecture?

    One of the main reasons for using a stream processing architecture is to handle multiple data streams. Sometimes, data arrives as a continuous stream of events or occurrences. Traditional batch processing methods require storing the data, pausing data collection, and processing it in batches. This approach introduces delays and makes handling real-time or near-real-time data analysis challenging.
    Multiple Streams: Stream processing is designed to handle never-ending data streams more effectively. It allows for continuous data ingestion and processing, enabling faster insights and analysis. With stream processing, patterns and trends can be detected in real-time, results can be inspected as they occur, and different levels of focus can be applied to the data. Additionally, stream processing architectures enable the simultaneous analysis of multiple streams, allowing for a more comprehensive view of the data. In simpler terms, stream processing allows for the immediate analysis and interpretation of data as it arrives, without waiting for batches or storing large amounts of data before processing. It enables real-time decision-making, faster response times, and the ability to extract valuable insights from streaming data more promptly.
    Processing Time and Storage: Stream processing differs from batch processing in processing time, storage requirements, and accessibility. In batch processing, data is accumulated over time before being processed simultaneously. On the other hand, stream processing processes data as it arrives, spreading the processing workload over time. This means that stream processing requires less hardware compared to batch processing. In some cases, the volume of data is so large that storing it becomes impractical. Stream processing addresses this challenge by continuously handling massive amounts of data while retaining only the most important information. This enables efficient processing of large-scale data streams without extensive storage resources.
    Accessibility: Additionally, a vast amount of streaming data, such as customer transactions, website visits, and IoT sensor data, is available. Stream processing provides a more natural and effective approach to handling and analyzing such streaming data. As IoT use cases become more prevalent and diverse, streaming data will continue expanding, making stream processing a valuable and accessible solution.
