Feed: Hazelcast Blog. Author: Neil Stevenson. In this example. we’ll look at doing some analytics on an online shop to gain insights into customer behaviour. Background Most online shops follow a similar pattern in terms of the customer experience. Users are presented with a catalogue of products on a browser page or mobile application, and may make selections from these. Items selected are added to a virtual shopping basket. At some stage in the process there is the chance to manipulate the contents of the virtual shopping basket, removing items, changing the quantities for items, or other amendments such as ...

Feed: MemSQL Blog. Author: Rick Negrin. It’s time for us to admit what we have all known is true for a long time; NoSQL is the wrong tool for many of the modern application use cases, and it’s time that we move on. NoSQL came into existence because the databases at the time couldn’t handle the scale required. The rise of this new generation of data services solved many of the problems of web scale and rapidly growing data sets when it was created more than a decade ago. NoSQL also offered a new, cost-effective method for cold storage/occasional batch ... Read More

Feed: Clustrix Blog. Author: Mike Azevedo. As a database vendor whose drop-in MySQL replacement database runs on-premise and on any cloud, we are often asked by our customers to guide them through a MySQL-compatible cloud database cost comparison. For this process, we have learned it is important to compare the total cost of ownership (TCO) of deploying ClustrixDB on different cloud platforms as compared to the MySQL-compatible offerings from the leading cloud vendors, such as AWS, GCP, and Microsoft Azure. We have discovered some hidden hard and soft costs that are important to consider. In this blog, we will share ... Read More

Feed: Blog – ArangoDB. Author: Daniel Larkin-York. Graph databases are often used to analyze relations within highly interconnected datasets. Social networks, recommendation engines, corporate hierarchies, fraud detection or querying a bill of materials are common use cases. But these datasets change over time and you as a developer or data scientist may want to time travel and analyze these changes. While ArangoDB may not come with built-in support for managing the revision history of graph data, we’ll show in this article how to manage it in a performant manner for some general classes of graphs. Best of all, this won’t ... Read More

Feed: Hazelcast Blog. Author: Scott McMahon. Introduction Apache Avro is primarily a data transfer mechanism, developed as part of the Apache Hadoop project and is similar to Thrift, Protocol Buffers, etc. Data is serialized into a compact binary format suitable for transmission across a network and/or storage to a persistence layer (i.e. Disk, DB, etc.). The data within the Avro format is discrete, finite, and packed into a defined structure. Because of the structure, it is referred to as a message (i.e. Avro Message). For object-oriented programming languages, Avro messages are generally serialized to and from objects. As this paper ... Read More

For instance Emin Demirci and many others have assembled some fun and interesting demonstration applications for Hazelcast Jet. Today we will walk through a simple Jet demo that shows how to implement a custom streaming source and sink and how to make streaming aggregations in Hazelast Jet. You will need the following tools installed: First clone the hazelcast-jet-demos repo: Now that you have the sources we can compile the realtime-image-recognition project: And now we simply execute the java ...
