Back in ancient history (2004) Google’s Jeff Dean & Sanjay Ghemawat presented their innovative idea for dealing with huge data sets – a novel idea called MapReduce Jeff and Sanjay presented that a typical cluster was made of 100s to few 1000s of machines with 2 CPUs and 2-4 GB RAM each. They presented that in the whole of Aug ...

With the release of latest influxdb-java driver version came along the InfluxbMapper. To get started we need to spin up an influxdb instance, and docker is the easiest way to do so. We just follow the steps as described here. Now we have a database with some data and we are ready to execute our queries. We have the measure ...

IT and big data projects can be complex and are often ambiguous by nature. In the case of big data projects, hypotheses about the information contained within the data are either proved or rejected, with new hypotheses then arising. Similarly, assumptions about project requirements are often built into IT projects and stacked on top of one another in advance. Yet, ...

Why would a data scientist use Kafka Jupyter Python KSQL TensorFlow all together in a single notebook? There is an impedance mismatch between model development using Python and its Machine Learning tool stack and a scalable, reliable data platform. The former is what you need for quick and easy prototyping to build analytic models. The latter is what you need ...

As continuation of big data query system blog, i want to share more techniques for building Analytics engine. Take a problem where you have to build system that will be used for analyzing customer data at scale.           What options are available to solve this problem ? – Load the data in your favorite database and have ...

In-memory approaches can achieve blazing speed by putting the working set of the data into the system memory. When all data is kept in memory, the need to deal with issues arising from the use of traditional spinning disks disappears. This means, for instance, there is no need to maintain additional cache copies of data and manage synchronization between them. ...

Editor’s Note: At Strata+Hadoop World 2016 in New York, MapR Director of Enterprise Strategy & Architecture Jim Scott gave a presentation on “Handling the Extremes: Scaling and Streaming in Finance.” As Jim explains, agility is king in the world of finance, and a message-driven architecture is a mechanism for building and managing discrete business functionality to enable agility.

In the past year, the big data pendulum for financial services has officially swung from passing fad or experiment to large deployments. That puts a somewhat different slant on big data trends when compared to 2016 trends. The question of big data hype versus reality has finally been put to rest for banks. This is further supported by the upward ...

There has been a lot of research in document image processing over the past 20 years, but not much research has been done in terms of parallel processing. Some of the solutions proposed for parallel processing have been to create threads of execution for each image, or to use GNU Parallel. In this blog post, you will learn how to ...
