Azure Cosmos DB features and specs

• Global Distribution
  Azure Cosmos DB allows for the distribution of data across multiple global regions, enhancing availability and delivering low-latency access to data for users around the world.
• Multi-Model Support
  It supports multiple data models including document, graph, key-value, and column-family APIs, making it versatile for a variety of applications and use cases.
• Automatic Scaling
  The database automatically scales up and down to meet the demands of application traffic, helping to manage workloads efficiently without manual intervention.
• High Throughput and Low Latency
  Cosmos DB offers high performance with single-digit millisecond read and write latencies, ensuring fast access to data for applications.
• Comprehensive SLAs
  Azure Cosmos DB provides industry-leading SLAs covering availability, throughput, consistency, and latency, offering strong guarantees for customers.
• Integrated Security
  It includes robust security features such as SSL/TLS encryption, role-based access control, and integration with Azure Active Directory for secure data management.

Possible disadvantages of Azure Cosmos DB

• Cost
  Azure Cosmos DB can be expensive, especially for high-throughput workloads and global distribution scenarios. Its pricing model based on provisioned throughput (RU/s) can add up quickly.
• Complexity
  Managing and optimizing Cosmos DB can be complex, requiring a deep understanding of its configuration settings, partitioning strategies, and indexing to achieve optimal performance.
• Vendor Lock-In
  As a proprietary service, using Cosmos DB tightly couples your application to Azure. This can make it difficult to migrate to other database solutions or cloud providers in the future.
• Consistency Models
  Azure Cosmos DB supports multiple consistency levels which can introduce complexity in designing applications. Developers need to understand and choose the appropriate consistency level for their specific use case.
• Limited Native Analytics
  Cosmos DB does not have built-in advanced analytics capabilities. Integrating with other services like Azure Synapse or Databricks may be necessary for sophisticated data analytics and reporting.

Titan Database features and specs

• Scalability
  Titan is designed to handle large graphs and scale out horizontally across multiple machines, providing robust support for expanding data and user load.
• Compatibility with Apache TinkerPop
  Titan supports the Apache TinkerPop graph computing framework, which makes it compatible with Gremlin, a powerful graph traversal language.
• Pluggable Storage Backend
  Titan offers flexibility by allowing the choice of different storage backends, such as Apache Cassandra, Apache HBase, or Oracle BerkeleyDB, which can optimize performance based on use case needs.
• High Availability
  Titan supports high availability configurations that ensure the database remains accessible and operations continue in the event of failures.
• Transactional Support
  The database provides full transactional support with ACID compliance, which ensures data integrity and consistency.

Possible disadvantages of Titan Database

• Complex Setup and Configuration
  Setting up Titan can be complex and requires careful configuration, especially when dealing with clustered environments or when selecting and configuring the appropriate backend.
• Maintenance Overhead
  The need for regular maintenance and fine-tuning can be resource-intensive, particularly for large-scale deployments.
• Steep Learning Curve
  With its flexibility and vast features, users may experience a steep learning curve, particularly those who are new to graph databases or distributed systems.
• Community and Ecosystem
  Being eventually succeeded by JanusGraph, the active development and community support around Titan might be less robust compared to newer alternatives.
• Integration Limitations
  While powerful, Titan may have limitations when integrating with certain systems or tools that are more easily accessible with newer graph databases.
