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.

Prometheus features and specs

• Powerful Query Language
  Prometheus uses PromQL, a flexible and powerful query language that allows for complex and detailed queries.
• Dimensional Data Model
  Prometheus employs a multidimensional data model with time series data identified by metric name and key-value pairs, offering great flexibility in data organization.
• Auto-Discovery
  It supports service discovery mechanisms to automatically locate and scrape metrics from jobs, simplifying the monitoring process.
• Alerting
  Prometheus includes built-in alerting capabilities that allow you to trigger alerts based on PromQL queries, which can be integrated with different alert management systems.
• Scalability
  Its architecture, which uses independent single servers, scales well, allowing you to handle a large number of time series efficiently.
• Open Source
  Prometheus is open-source and supported by a large community, offering transparency, regular updates, and numerous integrations.
• Easy Integration
  Thanks to its compatibility with various data exporting standards and a myriad of existing exporters, integrating Prometheus into existing systems is streamlined.

Possible disadvantages of Prometheus

• Single Points of Failure
  Prometheus instances operate independently, meaning that if a server goes down, the metrics it monitored will be unavailable unless replicated manually.
• Storage Overhead
  Prometheus can consume significant storage, especially for high-resolution time series data, which might necessitate careful planning and management.
• Limited Long-Term Storage
  By default, Prometheus is not designed for long-term storage of metrics and may require integration with other systems like Thanos or Cortex for this purpose.
• Complexity for Beginners
  The sheer number of features and the complexities associated with PromQL can present a steep learning curve for newcomers.
• Scaling Write Operations
  In high-scale environments, write operations might become a bottleneck due to the single-server nature of the Prometheus architecture.
• Lack of Native High Availability
  While Prometheus supports running multiple instances, it does not provide built-in high availability features out-of-the-box, necessitating additional configurations.
• No Built-in Authentication and Authorization
  Prometheus lacks native support for secure authentication and authorization, which means these features must be externally managed.
