Difference Between DynamoDB vs Cassandra

  • The DynamoDB and Cassandra are NoSQL databases to manage and operate the data of the applications.
  • The DynamoDB and Cassandra are based on key-value for grouping and distributing the hashed value of on the key.
  • The DynamoDB and Cassandra are databases to operate and maintain large-size data using keys and values.
  • The Cassandra was developed by apache to get column-oriented data storage and operate using a column of the database.
  • The DynamoDB offered by Amazon web services to get document-oriented data storage and operate it using documents argument.
  • The DynamoDB
  • The Cassandra is a free, open-source, and distributed NoSQL database for large-size data operations.
  • The DynamoDB is a document-oriented, fully managed, vertical, and horizontal scaling database.
  • The DynamoDB and Cassandra are created a schema-less table to store data and patricians them using a primary key.

Key differences

This database has differences based on the function, features, and operations. The following information explains the difference between DynamoDB and Cassandra databases.

  • The Apache Cassandra is a free and open-source database. The Amazon DynamoDB database pays for usable functions. The DynamoDB database is not free software.
  • The Apache Cassandra is a column-oriented database. This database uses SQL queries. The Amazon DynamoDB database is document-oriented. This database uses JSON format.
  • The DynamoDB creates 250 tables whereas the Cassandra database creates 500 tables.
  • The DynamoDB database stores 400KB of data. The Cassandra data stores 2GB of data. The Cassandra stores more data than the DynamoDB database.
  • The DynamoDB supports faster scans system than the Cassandra database.
  • The Cassandra database supports timestamp, time, counter, UUID data types while the DynamoDB does not use timestamp, time, counter, UUID data types.
  • The DynamoDB is a schemeless database because of the JSON format but the Cassandra database uses the schemas.

Type of database The DynamoDB database type is based on operation and data storage.

The database types are document-oriented databases and key-value databases.

 The Cassandra database type is based on operation and data storage.

The database type is a NoSQL data store database.
Operating system The DynamoDB database supports cross platforms.

You can work on any operating system of the computer such as Windows, Linux, and others.

 The Cassandra database supports cross platforms.

You can work on any operating system of the computer such as Windows, Linux, and others.
Syntax The common operation of the database is displayed table data to users.

The DynamoDB database syntax shows below.

get_item{
TableName: "table name"
}

 The common operation of the database is displayed table data to users.

The Cassandra database syntax shows below.

SELECT * FROM table name;
Parameter The get_item keyword is represented then returns table data.

The TableName keyword with the given table name shows the actual table.

The curly bracket is required from start to end database query.

 The basic keyword likes select, from, and others necessary to access table data.

The star (*) symbol has represented all columns of the table.

The semi-colon (;) symbol is represented end of the query.
Example The table data shows information. Here, the condition is applied to the table data.

get_item{
TableName: "marks",
Key{
"grade": "A",
"percentage": 85
}
}

 The table data shows information. Here, the condition is applied to the table data.

Select * from marks where grade = 'A' AND percentage = 85;
Security DynamoDB provides user authentication and user authorization for security and privacy. The Cassandra provides user authentication and user authorization for security and privacy.
Performance The database supports consistency with more nodes for request and response. The database supports consistency with more nodes for request and response.
Scans ●       The DynamoDB database has an expensive scans system.

●       The DynamoDB database provides fast scans system.

 ●       The Cassandra database has an expensive scans system.
