Possible disadvantages of Teradata

• Cost
  Teradata can be expensive to implement and maintain, which may not be practical for smaller organizations or those with limited budgets.
• Complexity
  The platform can be complex to set up and manage, often requiring specialized knowledge and skills, which might necessitate hiring or training staff.
• Vendor Lock-In
  Once integrated, migrating away from Teradata can be challenging, leading to potential vendor lock-in issues.
• Resource Intensive
  Running Teradata may require significant hardware and computational resources, which can add to the overall cost and complexity.
• Limited Flexibility
  Compared to some newer cloud-native solutions, Teradata can be less flexible in adapting to rapidly changing business requirements and technologies.

DynamoDB features and specs

• Scalability
  DynamoDB automatically scales up and down to handle your application's needs, with no intervention required. This allows for easy handling of traffic spikes and growth over time.
• Performance
  With its fast, predictable performance at any scale, DynamoDB ensures low-latency responses, even with large volumes of data.
• Fully Managed
  As a fully managed service, DynamoDB handles hardware provisioning, setup, configuration, replication, software patching, and backups, letting you focus on your application.
• Flexible Data Model
  DynamoDB supports both document and key-value store models, providing flexibility in how you structure your data.
• Security
  DynamoDB integrates with AWS Identity and Access Management (IAM) to provide fine-grained access control and encrypts data at rest and in transit.
• Global Tables
  You can create multi-region, fully replicated tables for high availability and globally distributed apps with low latency reads and writes.
• Event-Driven Architecture
  DynamoDB integrates with AWS Lambda for automatic triggering and the creation of event-driven architectures.

Possible disadvantages of DynamoDB

• Pricing Complexity
  DynamoDB's pricing model, which charges based on read and write capacity units, storage, and data transfer, can be complex and difficult to predict.
• Limited Query Capabilities
  DynamoDB does not support complex queries as well as traditional SQL databases. Querying capabilities are limited primarily to primary key attributes.
• Secondary Indexes
  While DynamoDB supports secondary indexes, their use can be limited and complex to manage effectively compared to relational databases.
• Consistency
  DynamoDB offers eventual consistency by default. While strongly consistent reads are available, they can be more expensive and slower.
• Data Size Limitations
  Each item in a DynamoDB table must be 400KB or less, limiting the amount of data you can store in a single item.
• Vendor Lock-In
  Using DynamoDB heavily ties your application to AWS, which can be a downside if you want to maintain flexibility in your cloud infrastructure choices.
