  ClickHouse is designed for fast processing of analytical queries, often performing significantly faster than traditional databases due to its columnar storage format and optimized query execution.
• Scalability
  The system is built to handle extensive datasets by scaling horizontally through distributed cluster configurations, making it suitable for big data applications.
• Real-time Data Ingestion
  ClickHouse supports real-time data ingestion and can immediately reflect changes in query results, which is valuable for use cases requiring instant data processing and analysis.
• Cost Efficiency
  The open-source nature of ClickHouse makes it a cost-effective option, especially when compared to other commercial data warehouses.
• SQL Compatibility
  ClickHouse features strong SQL support, which makes it easier for individuals with SQL expertise to transition and use the platform effectively.
• Compression
  ClickHouse employs advanced compression algorithms that reduce storage requirements and improve query performance.

Possible disadvantages of ClickHouse

• Complexity in Setup
  Setting up and managing ClickHouse, particularly in a distributed cluster environment, can be complex and require a higher level of expertise compared to some other database systems.
• Limited Transaction Support
  ClickHouse is optimized for read-heavy operations and analytics but does not support full ACID transactions, which limits its use for certain transactional use cases.
• Ecosystem and Tooling
  While the ecosystem is growing, ClickHouse still has fewer tools and third-party integrations compared to more mature databases, which can limit its utility in some environments.
• Resource Intensive
  Running ClickHouse, especially for large datasets, can be resource-intensive, requiring significant memory and CPU resources.
• Limited User Management
  The platform has relatively basic user management and security features, which may not meet the needs of enterprises with strict compliance and governance requirements.

Possible disadvantages of Teradata Database

• Cost
  Teradata is often considered expensive relative to other database solutions, particularly for smaller businesses or those with limited budgets, potentially limiting access to its advanced features.
• Complexity
  The setup and management of Teradata can be complex, requiring specialized knowledge and expertise, which might necessitate additional training or hiring of skilled personnel.
• Proprietary Nature
  Being a proprietary system, Teradata may lead to vendor lock-in and could limit flexibility in terms of integrating new, open-source technologies or platforms that are not supported by Teradata.
• Resource Intensive
  Typically requires significant computing resources for optimal performance, which may demand a higher infrastructure investment compared to lighter-weight alternatives.
• Limited Cloud Options
  Although Teradata offers cloud solutions, they may not be as mature or fully featured as some native cloud database solutions, which could be a limitation for businesses prioritizing a cloud-first strategy.
