The velocity, variety, and volume of the unstructured data are tedious to manage. Capturing, filtering and storing it for analysis and predictions is a real challenge. New software tools, technologies, and techniques are constantly developed to address this challenge. Hence, these demand for an ‘upgraded’ expertise of the professionals in this field. Listing the skills set of these new ‘tools’ in your resume will let the organizations see the potential value you can offer them!
#1. Apache Cassandra
Apache Cassandra is a high performance, free and open-source distributed NoSQL database management system. It follows a peer-to-peer architecture and is designed to handle large amounts of data across many commodity servers. Cassandra is a highly fault-tolerant DBMS with no single point of failure. This allows for the ‘high-availability’ of the data, as it is ‘replicated’ across the network servers.
Significance of Apache Cassandra;
There must be a crucial reason as to why companies like Reddit, Facebook, Netflix, etc. extensively use Cassandra. Besides offering a real-time performance and being open-source, Apache Cassandra offers ‘elastic-scalability.’ This means any number of nodes can be added or deleted from a cluster. This does not require changing query applications or a ‘cluster reboot.’
Moreover, Cassandra efficiently harnesses the processing power of several multicore machines to operate on large datasets.
How can Apache Cassandra help you?
There is a high demand for skilled professionals who can build and scale new infrastructure, platforms, and processes for an organization. Apache Cassandra offers you with relevant skills to undertake these operations.
#2. Apache Hadoop
Apache Hadoop is another open-source framework that uses the MapReduce programming model for distributed storage and processing of large datasets. It is based on a network of ‘computer-clusters’ built from the commodity hardware. Extensive usage by companies like Google, Amazon, etc. has made it the central store for Big data in the businesses. Thanks to it, even small-scale companies can now apply data-science to tackle various business problems.
Significance of Apache Hadoop;
Hadoop allows for running data exploration and analysis on full-datasets, without the need for sampling them. Writing a simple script on Hive or PIG will let you launch the MapReduce job directly on Hadoop over full-datasets. Also, Hadoop is essential mining massive datasets, essential for outlier detection, clustering, and recommendation engines. No wonder why it is vastly employed by e-commerce companies worldwide.
How can Apache Hadoop help you?
Besides the above-listed features, Hadoop is an excellent tool for large-scale ‘pre-processing’ of raw data. As a data science professional, your major time will be consumed in ELT (Extraction, Loading, and transformation of the data), cleaning and feature spotting in the data. Rest is just running it through the algorithms for predictions. Practical knowledge of this tool will let the companies know that you are here for their rescue, by undertaking this crucial and time-consuming process!
Neo4j is an ACID (Atomicity, Consistency, Isolation & Durability) compliant transactional database, with integrated ‘graph database management,’ graph storage, and processing. Neo4j is used to find relationships and make sense of the complete data set puzzle. This allows the data scientists to navigate the connections between the nodes in constant time. In a relational database, where many JOIN-SQL-queries slow down the system, Neo4j gives you an edge.
Significance of Neo4j;
As you may know, data cleaning and munging consume a majority of time than ‘actual-model-building.’ Sorting queries in huge volumes pose another challenge. These obstacles hinder the progress of a project, especially when they are running on collaborative efforts. Neo4j eases these tasks. It provides you with the ability to store unstructured and highly-connected data. It's feature like ‘Cypher’ cut on data munging time and traversing the ‘tree structure’ datasets. Moreover, when the data queries increase exponentially, Neo4j’s performance remains constant. Therefore, it is a better alternative to relational and non-relational databases like SQL and NoSQL.
How can Neo4j help you?
Neo4j is the latest and most sought-after tool in graphic database management. It helps the professionals operating on Big data to save time and complete the projects without much hassle. If you possess expertise in Neo4j, companies are looking out for people like you!

Significance of Apache Spark;
Apache Spark is a faster cluster-computing framework. It saves the data in RDDs (Resilient Distributed Datasets) for quick access. Apache Spark also allows to capture and analyze ‘high-velocity’ and ‘high-volume’ data in real-time. It also enables the data science teams to run graph processing to capture relationships between various data-points (or entities).
Think of it as a versatile tool that offers iterative processing, speed and rapid access to the data-clusters. Spark has been used in building fraud detection applications, log processing for live-stream websites, etc.
How can Apache Spark help you?
Since Spark meets many potential needs at once, it is widely used by the organizations.

Apache NiFi is an open-source ‘data logistics’ framework for facilitating the flow of data across systems. It is written in Java and employs ‘flow-based’ programming for real-time automated data flow management. NiFi allows for effective-load spreading, handling extreme transaction rates and copy-on-write data feature. This is achieved through content-repository and write-ahead log applications integrated with Apache NiFi. Apache NiFi prioritizes the data queues, buffers the data (within the data queues) and allows to create flow-specific configurations (in case of critical and fault-intolerant data).
Significance of Apache NiFi;
Data flow between various systems and DBMS is a challenging task. It often witnesses disk fails, the network fails, and software crashes. Also, sometimes the rate of data access can outrun the rate of consumption. This can hamper the data-delivery chain. Apache NiFi enters the scenario with a solution. It provides a single interface for all the data flow operations, with cross-domain, cross-OS and cross-protocol data transfers. The flow-based-programming architecture of NiFi has allowed the enterprises to transfer their valuable data between multiple databases without failure easily.

Apache Kafka is an open-source stream processing platform written in Java and Scala. It provides a high-throughput (High volume and high speed of data flow) on a unified low-latency platform. Apache Kafka is used for real-time handling of data feeds with reliability and robustness. It acts as a ‘publish-subscribe’ messaging system that maintains a feed of messages topic-wise. Here, ‘messages’ are nothing but ‘byte-arrays’ which can be used to store data objects in any format (Avro, JSON,etc.).
Significance of Apache Kafka;
In Big data analysis, Kafka is used in the ‘extraction’ step of ETL operation. Extraction step is nothing but ‘sourcing’ of data from multiple sources. Since Kafka classifies the messages under various classes (or topics), the extraction becomes easier.
Moreover, Kafka is used for ‘flagging’ transactions in real-time. For example, exchange of virtual entities among players of an online game. Kafka monitors for any unfair trade or suspicious activity by the players logged-in through multiple accounts. Besides this, Apache Kafka is used in website activity tracking, operational metrics and log aggregation of the data.
How can Apache Kafka help you?

Samza uses Kafka for messaging and Hadoop YARN (Yet Another Resource Negotiator) for fault tolerance. In short, it can be called a distributed stream processing framework. It contains features like simple API (Application Programming Interface), fault tolerance, extensibility, processor isolation, etc. Apache Samza can run with other messaging systems with a pluggable API.
Significance of Apache Samza;
Samza locates storage and processing of batch data on the same machine. This allows for efficient work in a condition where the data won’t fit in the memory. Moreover, Apache Samza is being used by LinkedIn and many other companies. For example, in a LinkedIn data center, the most massive Samza task is to process one-million messages per second during peak online traffic.
How can Apache Samza help you?
Companies often come across scenarios where they have to process many Gbs of data per partition. Apache Samza comes in handy for such tasks. It allows to add/remove various codebases without much ‘ripple’ effects. Companies like Intuit, Quantiply, and LinkedIn are already exploiting Samza. So why not learn it?
