Data structure and schema flexibility needed
Data structure determines the management and storage of your data. Consider a data structure that aligns with the requirements of your data storage.
The database has a flexible and pre-defined schema. A database with flexible schema stores unstructured data while fixed schema works with structured data structures. Your data storage must be easy and accessible at any time which makes this factor significant.
Query patterns and scalability requirements
A query pattern is necessary for quickly searching data within the database. An efficient query index reduces the time in getting the appropriate information stored within the huge database.
NoSQL databases are scaled horizontally which means it allows adding more storage and processing power as your business needs increase. Choosing a database with good query patterns and scaling capability is critical in searching data and meeting needs.

Neptune has features for multi-zone replication, replica reading, and point-in recovery. It provides in-transit encoding and supports ACID transactions.
Consider Factors Beyond Features For Your AWS NoSQL Database
Integration with other AWS services
Considering the integration of your chosen NoSQL AWS database with other AWS is critical. Integration enables communication between components within distributed systems, microservices, and serverless applications. Integration with other databases does not require you to change your entire database architecture based on your existing application.
Compliance and security requirements
Security and compliance are critical factors when storing sensitive data. Your No SQL database offers multiple security features like audit logging, access control, and encryption at rest as well as in transit.
Understanding the security features that a database offers is important so that you can ensure the security of your data. Apart from security features, your database should also follow IT compliance regulations like SOC 1, FISMA, ISO 9001, ISO 27017, and many more. Compliance assures your customers that their data is safe within regulatory standards.
Community support and documentation
A community database is a multi-channel gated community to support customers and it is created and maintained by a library. Choosing a database that has robust community support is always a good choice.
Community support helps the business in creating and maintaining useful customer data that your database can retain for making quick decisions. Choose a database that has clear documentation as it ensures that data is secured and well maintained. Database documentation ensures that it is easier to locate required information instantly.
Vendor lock-in and future scalability
Vendor lock-in is a situation where switching to a different vendor costs so high that the customer gets stuck with the original vendor. Always understand your database cloud provider and its terms and conditions before selecting a database.
You should also have a backup plan ready in case of adverse situations. Look for a database that promises future scalability and can increase as your data and business increase in the future.
