DynamoDB vs MongoDB vs Cassandra for Fast Growing Geo-Distributed Apps. MongoDB is better than Cassandra if your application requires secondary indices along with flexibility in the data model. Additionally, brush up on your familiarity with these MongoDB interview questions. Cassandra performs better in applications with heavy data load as it can provide multiple master nodes in a cluster. MongoDB is not ideal for applications with heavy data load as it can’t scale with the performance. IT professionals use MongoDB for content management systems, IoT applications, mobile applications, and whenever you want a real-time view of your data. MongoDB has only one master node in the cluster at any given point in time, which is the only point to cater incoming requests.

Cassandra is more scalable in comparison with MongoDB as it can have more than one master node in a cluster. Who Uses These Databases? MongoDB has its own aggregation framework, though it’s best suited for small to medium-sized data traffic loads, MongoDB supports ad-hoc queries, aggregation, collections, file storage, indexing, load balancing, replication, and transactions; Cassandra offers core components like clusters, commit logs, data centers, memory tables, and Node. Amazon recommends using a global secondary index, but that’s definitely for advanced programmers only.

Node.js Express Tutorial: Create a User Management System, Big Data Hadoop Certification Training course, Big Data Hadoop Certification Training Course, AWS Solutions Architect Certification Training Course, Certified ScrumMaster (CSM) Certification Training, ITIL 4 Foundation Certification Training Course, Data Analytics Certification Training Course, Cloud Architect Certification Training Course, DevOps Engineer Certification Training Course, Provides security and eliminate redundancy, Allows data sharing and multi-user transaction processing, Follows the ACID concept (Atomicity, Consistency, Isolation, and Durability), Supports multi-user environments that allow users to access and manipulate data in parallel, It follows peer-to-peer architecture rather than master-slave architecture, so there isn’t a single point of failure, Cassandra can be easily scaled down or up, It features data replication, so it’s fault-tolerant and has high availability, It’s a high-performance database manager that easily handles massive amounts of data, It’s schema-free (or, schema-optional), so you can create your columns within the rows, and there is no need to show all the columns required to run the application, It supports hybrid cloud environments since Cassandra was designed as a distributed system to deploy many nodes across many data centers, It doesn’t support ACID and relational data properties, Because it handles large amounts of data and many requests, transactions slow down, meaning you get latency issues, Data is modeled around queries and not structure, resulting in the same information stored multiple times, Since Cassandra stores vast amounts of data, you may experience JVM memory management issues, Cassandra was optimized from the start for fast writes, reading got the short end of the stick, so it tends to be slower, Finally, it lacks official documentation from Apache, so you need to look for it among third-party companies, Provides support for in-Memory or WiredTiger storage systems, It’s flexible and agile thanks to its schema-less database architecture, It offers a deep query capability, which supports dynamic document queries using a dedicated language that is almost as powerful as SQL, You don’t need to map or convert application objects into database objects, It accesses data faster thanks to employing internal memory for storing the working set. Open source: Cassandra and MongoDB are both open source. In this post, we look beyond Amazon’s marketing claims to explore how well DynamoDB satisfies the core technical requirements of fast growing geo-distributed apps with low latency reads, a common use case found in today’s enterprises. MongoDB supports a “single master” model. It helps you to makes real-time … Database Location. I should preface this by saying I do not have production experience with DynamoDB, so this is largely based on its features and capabilities as reported in the media and various tech blogs.
