Presto DB features and specs

• High-Performance Query Engine
  Presto is designed for high-performance querying, capable of performing complex analytics and large-scale data processing at interactive speeds.
• Distributed SQL Query Engine
  Presto can scale out to large clusters of machines, allowing for efficient distribution of queries over multiple servers to handle big data workloads.
• Versatility
  Supports querying data from multiple data sources such as Hadoop, relational databases, NoSQL databases, and cloud object storage within a single query.
• ANSI-SQL Compatibility
  Presto supports ANSI SQL, making it easier for users familiar with SQL to adapt and write queries without a steep learning curve.
• Open Source
  Presto is an open-source project, which means it benefits from continuous community contributions and improvements, keeping it up-to-date and robust.
• Extensible
  Presto's architecture is designed to be extensible, allowing users to add custom functions and connectors, tailored to specific needs.

Possible disadvantages of Presto DB

• Resource Intensive
  High performance comes with significant resource requirements, necessitating robust infrastructure to realize its full potential.
• Complex Configuration
  Setting up and configuring Presto can be complex and time-consuming, often requiring expertise and an understanding of its various components.
• Limited Support for Transactions
  Presto is primarily designed for reading data and performing analytics, and it has limited support for transactional processing compared to traditional relational databases.
• Community Support
  While it has a vibrant open-source community, users may find the support less comprehensive than that provided by commercial enterprise solutions.
• Latency for Small Queries
  Designed for big data and complex queries, Presto may exhibit higher latency for small, simple queries compared to specialized databases optimized for such use cases.
• Maintenance Overhead
  Managing and maintaining a Presto cluster can be labor-intensive, requiring ongoing tuning and maintenance to ensure optimal performance and reliability.

Apache Cassandra features and specs

• Scalability
  Apache Cassandra is designed for linear scalability and can handle large volumes of data across many commodity servers without a single point of failure.
• High Availability
  Cassandra ensures high availability by replicating data across multiple nodes. Even if some nodes fail, the system remains operational.
• Performance
  It provides fast writes and reads by using a peer-to-peer architecture, making it highly suitable for applications requiring quick data access.
• Flexible Data Model
  Cassandra supports a flexible schema, allowing users to add new columns to a table at any time, making it adaptable for various use cases.
• Geographical Distribution
  Data can be distributed across multiple data centers, ensuring low-latency access for geographically distributed users.
• No Single Point of Failure
  Its decentralized nature ensures there is no single point of failure, which enhances resilience and fault-tolerance.

Possible disadvantages of Apache Cassandra

• Complexity
  Managing and configuring Cassandra can be complex, requiring specialized knowledge and skills for optimal performance.
• Eventual Consistency
  Cassandra follows an eventual consistency model, meaning that there might be a delay before all nodes have the latest data, which may not be suitable for all use cases.
• Write-heavy Operations
  Although Cassandra handles writes efficiently, write-heavy workloads can lead to compaction issues and increased read latency.
• Limited Query Capabilities
  Cassandra's query capabilities are relatively limited compared to traditional RDBMS, lacking support for complex joins and aggregations.
• Maintenance Overhead
  Regular maintenance tasks such as node repair and compaction are necessary to ensure optimal performance, adding to the administrative overhead.
• Tooling and Ecosystem
  While the ecosystem for Cassandra is growing, it is still not as extensive or mature as those for some other database technologies.
