OpenTSDB features and specs

• Scalable
  OpenTSDB is designed to handle large volumes of time series data, making it suitable for environments that require scalability.
• High Performance
  It can efficiently process and query vast amounts of data quickly due to its write-optimized storage and architecture.
• Real-time Analytics
  OpenTSDB supports real-time data collection and analysis, providing immediate insights into system performance and metrics.
• Integration with Hadoop
  It is built on top of HBase, allowing seamless integration with Hadoop ecosystems to leverage distributed storage and processing.
• Customizable Queries
  OpenTSDB provides a powerful query language that enables users to customize and execute complex queries on time series data.

Possible disadvantages of OpenTSDB

• Complex Setup
  Setting up and configuring OpenTSDB can be complex and requires familiarity with both HBase and Hadoop.
• Resource Intensive
  Running OpenTSDB can be resource-heavy due to its reliance on HBase, which requires careful tuning and monitoring.
• Limited Built-in Visualization
  OpenTSDB does not offer built-in visualization tools, requiring users to integrate with third-party visualization solutions.
• Maintenance Overhead
  Ongoing maintenance and upgrades of the underlying HBase and Hadoop components can add to the operational overhead.
• Steep Learning Curve
  For new users, understanding and fully leveraging OpenTSDB's capabilities can involve a steep learning curve.

SQLite features and specs

• Zero Configuration
  SQLite does not require any server setup or configuration, allowing for easy integration and deployment in applications.
• Lightweight
  It is extremely lightweight, with a small footprint, making it ideal for embedded systems and mobile applications.
• Self-Contained
  SQLite is self-contained, meaning it has minimal external dependencies, which simplifies its distribution and usage.
• File-Based Storage
  Data is stored in a single file, which makes it easy to manage and transfer databases as simple files.
• ACID Compliance
  SQLite supports Atomicity, Consistency, Isolation, and Durability (ACID) properties, ensuring reliable transactions.
• Cross-Platform
  SQLite is available on numerous platforms, including Windows, MacOS, Linux, iOS, and Android, providing a broad compatibility range.
• Public Domain
  SQLite operates under the public domain, allowing for unrestricted use in commercial and non-commercial applications.

Possible disadvantages of SQLite

• Limited Scalability
  SQLite is not designed to handle high levels of concurrency and large-scale databases, making it less suitable for large, high-traffic applications.
• Write Performance
  Write operations can be slower compared to server-based databases, especially under heavy write loads.
• Lack of Certain Features
  SQLite lacks some advanced features offered by other RDBMS like stored procedures, user-defined functions, and full-text search indexing.
• Security
  As SQLite is file-based, it might lack some of the security features present in server-based databases, such as sophisticated access control.
• Concurrency
  SQLite uses a locking mechanism to control access to the database, which can lead to contention and performance bottlenecks in highly concurrent environments.
• Backup and Restore
  While it's straightforward to copy SQLite database files, it lacks the advanced backup and restore features found in more complex RDBMS.
