Which is cheaper DynamoDB or MongoDB?
Determining which database system is cheaper between DynamoDB and MongoDB largely depends on your specific use case, resource requirements and associated costs.
Let’s first take a look at the pricing models for both the database systems. DynamoDB follows a pay-per-request pricing model which implies that you need to pay for only the requests that you make to the database, depending on the amount of data you store and the provisioned read/write throughput capacity you require.
In case you have spikes in demand, DynamoDB automatically scales up the resources required so as to meet your application requirements while charging you based on actual usage. This can be a cost-effective model in situations where workloads are not consistently high, and fluctuation in resources is needed.
On the other hand, MongoDB’s pricing model is based on a combination of features, services, and usage volume. It provides a free Community edition, as well as multiple paid versions that provide enterprise features, like analytics, advanced security, and enterprise-level support including a cluster manager, backup, monitoring, and much more.
As such, pricing will vary depending on the specific requirements, including the number of database nodes and the amount of data being stored.
That being said, comparing the costs of these two options is not as straightforward as it may appear. There are several factors to consider while comparing the cost of both the systems, including storage, compute, administration, maintenance and archival costs. Without comparing these factors, it is difficult to determine which is cheaper between the two.
It is noteworthy that DynamoDB is a managed service, which implies that Amazon takes care of the entire infrastructure and maintenance costs. Hence, if your workload aligns with DynamoDB’s capabilities, you can potentially reduce the cost of ownership, in terms of administration or maintenance costs associated with running the database.
On the other hand, MongoDB requires a significant amount of manual administration and maintenance that can potentially increase the total cost of ownership. In addition, it is worth noting that setting up and configuring MongoDB requires a specialist, or someone with experience in working with the database system, which could translate into additional administrative costs.
Both DynamoDB and MongoDB are robust and leading database systems in the market, and determining which is cheaper depends on various factors specific to your use case. Therefore, it is important to evaluate both systems closely based on your specific requirements and choose the one that best fits your needs, rather than solely on the basis of the cost.

How long does DynamoDB store data?
DynamoDB is a NoSQL database service that is extremely popular for its scalability, reliability, and flexibility. When it comes to the question of how long DynamoDB stores data, the answer is that it depends on the type of data stored and the retention policy set by the user.
DynamoDB is designed to provide high performance and high scalability, and it allows users to create tables with a virtually unlimited amount of data. The service uses a distributed architecture that allows users to store petabytes of data across multiple regions and availability zones.
One of the key features of DynamoDB is its flexible data retention policy. By default, DynamoDB stores data indefinitely, which means that your data will be available for as long as you need it. However, you can configure your table to automatically delete old or unused data by setting up time-to-live (TTL) or expiring attributes.
With TTL, you can set up an expiration date on a per-item basis. Once the expiration time has been reached, the item is deleted from the table automatically. This feature is useful for situations where you have data that is only relevant for a period of time, such as user login data, session data, or cache data.
In addition to TTL, DynamoDB also supports expiring attributes, which allows you to set a time range for the data to be available. This feature is useful for situations where you need to keep data for a specific period, such as audit logs or compliance records.
The length of time DynamoDB stores data depends on the retention policy set by the user.

What are the limitations of DynamoDB?
DynamoDB is a NoSQL database management system provided by Amazon Web Services (AWS) that is designed to deliver fast and predictable performance with seamless scalability. However, despite being a highly sophisticated and flexible database management system, DynamoDB is not immune to limitations that can impact its functionality and suitability for certain use cases.
In this answer, we will discuss some of the key limitations of DynamoDB.
1. Limited Query Capabilities:
DynamoDB is designed to facilitate high-speed read/write operations, making it an excellent choice for applications that require fast and predictable performance. However, DynamoDB’s query capabilities are relatively limited compared to traditional relational databases. While DynamoDB supports basic querying functionalities, it lacks more advanced capabilities like JOIN operations, table scans, and filtering capabilities.
2. Limited Secondary Indexing:
DynamoDB provides secondary indexes that allow users to create additional indexes along with the primary index. However, the limitations of the secondary indexing in DynamoDB can impact working with complex data sets. For example, DynamoDB only allows users to create up to five local secondary indexes and global secondary indexes per table.
Additionally, the user must define a partition key and sort key to create secondary indexes, which creates limitations in data modeling.
3. Consistency Model Limitations:
DynamoDB offers two types of consistency models: strong and eventual consistency. Strong consistency ensures that all data reads and writes are made to a single copy of the data, making it highly reliable. However, strong consistency may not be feasibly implemented for highly distributed systems, leading to eventual consistency.
Eventual consistency is more relaxed and allows for eventual consistency across all replicas, but may not offer a precise representation of the latest data.
4. Limited Schema Changes:
DynamoDB has a fixed schema, meaning that once the schema is defined, it cannot be altered. This can be a limitation in some use cases where there is a need to change the database schema due to evolving business requirements. In such cases, altering the schema can require significant downtime or migration of data to a new database.
5. Expensive at Scale:
DynamoDB is not a cost-effective option for smaller applications as it comes with a high price per read/write operation. The pricing model of DynamoDB is complex, as it is based on the provisioned throughput capacity, data storage, and data transfer bandwidth. The pricing becomes expensive for larger applications that require a high amount of throughput capacity.
Although DynamoDB offers excellent performance and scalability, users must be aware of its limitations before implementing it in production. The lack of advanced querying capabilities, secondary indexing limitations, inconsistency models, fixed schema changes, and high pricing costs can impact its suitability for certain use cases.
Adequate evaluation of these limitations with careful consideration of specific use cases can help users determine if DynamoDB is the right database management system to meet their needs.
