MongoDB vs Cassandra

Difference Between MongoDB vs Cassandra

Mongo DB is open-source and free database software that is a NoSQL type database program. It supports cross-platform and is a document-oriented database. It was written based on C++, C, and JavaScript programming languages. MongoDB was licensed under Apache License. It supports different operating systems like Windows, Linux, Free BSD, Linux, OS X, Solaris, etc. Apache Cassandra is an open-source and freely distributed No-SQL database management system developed and designed to handle large-scale data across distributed commodity servers. Cassandra a No SQL database’s main objectives are such as simple design structures, high availability and horizontal scaling, etc.

Let us study much more about MongoDB and Apache Cassandra in detail:

• Mongo DB has various licensing versions too. It was developed by MongoDB Inc. It first appeared and was released in the year 2009. MongoDB can also be used as a file system. Apache Cassandra was developed by Apache Software Foundation which was initially released in the year 2008. It supports cross-platform Operating System Cassandra database provides high availability and zero single points of failure.
• It also wins in the case of Scalability. Compared to relational databases, NoSQL databases support powerful queries and transactions by following ACID (Atomicity, Consistency, Isolation, and Durability) properties.
• Apache Cassandra is having elastic scalability, fast linear performance, easily distributed architecture, faster queries and transaction support, faster read and write capabilities. It was initially developed at Facebook for searching the messages in Inbox and was made open source later by Facebook. Cassandra has a Query language called CQL which is Cassandra Query language.

Key differences between MongoDB and Cassandra

Let us discuss some of the major differences between MongoDB and Cassandra:

1. Mongo DB supports ad-hoc queries, replication, indexing, file storage, load balancing, aggregation, transactions, collections, etc., whereas Apache Cassandra has main core components such as Node, data centers, memory tables, clusters, commit logs, etc.
2. Mongo DB stores data in such a way that the data is stored in BSON files on disk whereas Apache Cassandra Node stores the data in it and its data centers consist of all the nodes.
3. Mongo DB cluster contains different components such as shard, mongos and config servers to store metadata information and configuration settings details whereas Apache Cassandra cluster is distributed across different machines to handle failures and maintains the replicas to maintain the operations and transactions with high availability.
4. Mongo DB works in the form of replicating all the instances in the entire server which is not done for a single database level whereas Apache 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.
5. Mongo DB can facilitate adding a new field to every document in the entire collection which is adaptable whereas Apache Cassandra has the facility to add columns whenever or wherever wanted apart from the traditional relational-based database systems.
6. Mongo DB supports different types of data types along with some binary data and object types whereas Apache Cassandra deals with unstructured data and has a flexible schema to handle data read-write operations.
7. Mongo DB architecture is designed in such a way that it balances the data automatically using its inbuilt feature in a shared cluster when the data grows as per requirement whereas Apache Cassandra is wide column-based storage architecture based on the Big Data technologies and Dynamo DB database.
8. Mongo DB is ranked in the top 5 in terms of engine ranking whereas Apache Cassandra scored less in terms of DB engine ranking in terms of popularity and trending.
9. Mongo DB was released in 2009 whereas Apache Cassandra was initially released in February 2008.
10. Mongo DB supports multiple cross-platform operating systems such as Linux, Solaris, Windows, BSD, OS X, etc. whereas Apache Cassandra supports Linux, OS X, Windows, BSD Operating Systems.
11. Mongo DB supports Java, Perl, PHP, node.js, C++, C#, .NET, Python, etc. whereas Apache Cassandra supports most of the popular object-oriented programming languages such as C#, C++, Java, Go, Erlang, JavaScript, Perl, PHP, Python, Ruby, Scala, etc.

MongoDB and Cassandra Comparison Table

The primary comparison between MongoDB and Cassandra are discussed below:

Basis of Comparison	MongoDB	Cassandra
License	Open Source No SQL database licensed under Apache License	Open Source No SQL database developed by Apache Open Source Projects
Environment	Developed by MongoDB Inc. and supports cross-platform systems	Provided by Apache projects and useful for distributed environments
Performance	Provides faster query execution performance due to a simple schema	Provides high scalable and linear performance
Scalability	Writing scalability is limited in MongoDB	High scalability.
Pricing	Open Source and depends on the implementation and has different licensed versions too	Open Source and depends on the implementation
Speed	Not faster compared to Cassandra in terms of read operations	Faster for queries of smaller scripts
Query Speed	Reduces network speed while multi-query execution	Multi-Query execution capacity
Data Integration	Fast and Flexible with different applications and tools such as Big Data.	Fast and Flexible with different tools
Data Format	BSON and JSON data formats.	No SQL, JSON data formats.
Ease of Use	Easier to write scripts	Easier to write scripts and queries.

Conclusion

Mongo DB is No SQL and document-oriented database and Apache Cassandra is also a No SQL-based database system, where Elasticsearch is clearly a winner in terms of the latest object-oriented or No SQL databases is based on Lucene developed by Apache which is a good index-based search engine. In terms of performance scalability and features, Apache Cassandra can be considered the best database in the case of large amounts of data to be handled and in terms of query execution speed and optimization.

The advantages of MongoDB are that the complex data can be easily be modeled because of the JSON format support provided. This gives much popularity for the Mongo DB compared to the Cassandra. Both MongoDB vs Cassandra Performance databases have their greater advantages depending on the requirements and the amount of data about to be handled in the application decides the choice to be made.
