MongoDB was released in 2009 by MongoDB Inc. Moreover, every row in Cassandra does not need to have the same columns. Cassandra does not have a built-in aggregation framework. However, unlike relational databases, you can create columns and tables on the fly. MongoDB vs. Cassandra: Features Both technologies play a vital role in their fields, with their similarities between MongoDB and Cassandra showing their common features and differences show, uniqueness of these technologies. MongoDB employs an objective-oriented or data-oriented model Cassandra offers an assortment of master nodes, while MongoDB uses a single master node. Here is a comprehensive look at Cassandra vs MongoDB, and how the two databases stack up against each other. Cassandra is written only in Java language. High Availability: MongoDB and Cassandra Hadoop gets … 9) MongoDB supports multiple cross-platform operating systems such as Linux, Solaris, Windows, BSD, OS X, etc. It’s never tough going with MongoDB because its solves complicated situations but still it cannot be regarded as the perfect one as it doesn’t help a user in complicated transactions. Due to its flexible data model and secondary indexes, it can access any property of a stored object (even when it is nested). 1) MongoDB supports ad-hoc queries, replication, indexing, file storage, load balancing, aggregation, transactions, collections etc. 2) MongoDB stores data in such a way that the data is stored in BSON files on disk. MongoDB and Cassandra although both are NoSQL, still they are different from one another as Cassandra suits more for semi-structured data, while MongoDB offers lot more flexibility to the unstructured data with its object-oriented approach. Long long ago (2011) in a Littleton founder's basement not so far away, the decision was made to use MongoDB as the persistence engine for our Person API product.
If you want to have a native tool and your data traffic is not very high, MongoDB is a winner. Cassandra - A partitioned row store. It's highly distributed architecture means you can continue writing to a cluster even when nodes fail. See for yourself how we can make data integration such a breeze.

They are relatively young compared to MySQL which debuted in the mid-’90s. When users tend to construct the conventional data more dependable with more speed, they will come closer towards Cassandra. HBase’s use cases consist of online log analytics, write-heavy applications, and apps that need a large volume, such as Facebook posts, Tweets, etc. To understand Cassandra a little bit, it is introduced in the year 2008 by a couple of developers from Facebook which was later released as an Open Source project. Young. So let’s check out the basic differences between MongoDB and Cassandra. 4) Cassandra has a replication factor that defines the number of copies of data across different machines to receive multiple copies of data to maintain fault tolerance and high availability. Both Cassandra and MongoDB are NoSQL databases that offer enterprises reliable scalability for modern data needs. The extent to which these indexes are supported is not the same in MongoDB and Cassandra. With MongoDB, you might have to wait 10 to 40 seconds for write operations in case of a node failure since it only allows a single master. Sensor data. Aggregation allows you to run complex queries. It can run an ETL pipeline to aggregate stored data and return results. MongoDB’s activities and performance are similar to the old style of storage systems, that’s why it is much easier and comfortable to use. Unlike MongoDB, Cassandra uses a masterless “ring” architecture which provides several benefits over legacy architectures like master-slave architecture. Cassandra’s structural design supports multiple numbers of data centres working together. Additionally, there is a large set of use cases related to Cassandra Hadoop integration.
