Stream-processing systems are designed to support an emerging class of applications that require sophisticated and timely processing of high-volume data streams, often origi-nating in distributed environments. Unlike traditional data- processing applications that require precise recovery for cor-rectness, many stream-processing applications can tolerate and benefit from weaker recovery. Distributed stream processing engines have been on the rise in the last few years, first Hadoop became popular as a batch processing engine, then focus shifted towards stream processing engines. Stream processing engines can make the job of processing data that comes in via a stream easier than ever before and by using clustering can enable processing data in larger sets in a timely manner.

Distributed Stream Processing (DSP) systems are critical to the processing of vast amounts of data in real-time. It is here where events must traverse a graph of streaming operators to allow for the extraction of valuable information. There are many scenarios where this information is at its most valuable at the time of data arrival and therefore systems must deliver a predictable level of. Distributed stream processing systems offer a highly scalable and dynamically configurable platform for time-critical applications ranging from real-time, exploratory data mining to high performance transaction processing. Resource management for distributed stream processing systems is complicated by a number of factors - processing elements are constrained by their producer-consumer.

The growing number of applications of such genre has led to the creation of Stream Processing Systems (SPSs), systems that abstract the details of real-time applications from the developer. More recently, the ever increasing volumes of data to be processed gave rise to distributed SPSs. Currently there are in the market several distributed SPS Though there are a variety of Distributed Stream Processing Systems (DSPSs) that facilitate the development of streaming applications, resource management and task scheduling is not automatically handled by the DSPS middleware and requires a laborious process to tune toward specific deployment targets. As the advent of cloud computing has supported renting resources on-demand, it is of great.

With the quantity of data growing and the speed of data increasing, big data.

However, a stream processing system can't store the whole incoming stream data for future references. A technique is needed to get rid of the expired data and free the space for more incoming data in an archive storage. Hence keeping in view, the storage space limitation, integration issues and its associated cost, we try to optimize the stream archive storage and free more space for future. Stream-processing workloads and modern shared cluster environments exhibit high variability and unpredictability.

Stateful Stream Processing in a Distributed System. Let's imagine that we are counting the votes during a presidential election. The classic batch approach would be to wait until all votes have been cast and then proceed to count them. Even though this approach produces a correct end result, it would make for very boring news over the day because no (intermediate) results are known until the. Several distributed stream processing engines exist and could be applied to the problem [2, 11, 14]. However, an im-portant challenge when running distributed SPEs in server clusters is fault-tolerance. As the size of the cluster grows, so does the likelihood that one or more servers will fail. Server failures include both software crashes and hardware failures. In this paper, we assume server. Recent work in large-scale distributed stream processing tackle various research challenges in both the application domain as well as in the underlying system. The main focus of this paper is to highlight some of the signal processing challenges such a novel computing framework brings.
