AWS Lambda features and specs

• Scalability
  AWS Lambda automatically scales your application by running your code in response to each trigger. This means no manual intervention is required to handle varying levels of traffic.
• Cost-effectiveness
  You only pay for the compute time you consume. Billing is metered in increments of 100 milliseconds and you are not charged when your code is not running.
• Reduced Operations Overhead
  AWS Lambda abstracts the infrastructure management layer, so there is no need to manage or provision servers. This allows you to focus more on writing code for your applications.
• Flexibility
  Supports multiple programming languages such as Python, Node.js, Ruby, Java, Go, and .NET, which allows you to use the language you are most comfortable with.
• Integration with Other AWS Services
  Seamlessly integrates with many other AWS services such as S3, DynamoDB, RDS, SNS, and more, making it versatile and highly functional.
• Automatic Scaling and Load Balancing
  Handles thousands of concurrent requests without managing the scaling yourself, making it suitable for applications requiring high availability and reliability.

Possible disadvantages of AWS Lambda

• Cold Start Latency
  The first request to a Lambda function after it has been idle for a certain period can take longer to execute. This is referred to as a 'cold start' and can impact performance.
• Resource Limits
  Lambda has defined limits, such as a maximum execution timeout of 15 minutes, memory allocation ranging from 128 MB to 10,240 MB, and temporary storage up to 512 MB.
• Vendor Lock-in
  Using AWS Lambda ties you into the AWS ecosystem, making it difficult to migrate to another cloud provider or an on-premises solution without significant modifications to your application.
• Complexity of Debugging
  Debugging and monitoring distributed, serverless applications can be more complex compared to traditional applications due to the lack of direct access to the underlying infrastructure.
• Cold Start Issues with VPC
  When Lambda functions are configured to access resources within a Virtual Private Cloud (VPC), the cold start latency can be exacerbated due to additional VPC networking overhead.
• Limited Execution Control
  AWS Lambda is designed for stateless, short-running tasks and may not be suitable for long-running processes or tasks requiring complex orchestration.

Apache Tika features and specs

• Versatile File Format Support
  Apache Tika can detect and extract metadata and structured text content from over a thousand different file types, making it a highly versatile tool for content extraction across varied documents.
• Open-Source
  Being open-source, Apache Tika allows developers to contribute to its development and customize it to meet specific needs, as well as providing transparency in its operations.
• Ease of Integration
  Tika can be easily integrated with Java applications as it is a Java library, and it also provides RESTful and command-line interfaces for use in other programming environments.
• Active Community and Support
  As an Apache project, Tika benefits from an active community that provides documentation, forums, and contributions which helps in troubleshooting and improving the tool.
• Extensive Language Support
  Apache Tika supports text extraction and language detection for a wide range of human languages, aiding in multilingual content handling.

Possible disadvantages of Apache Tika

• Performance Overhead
  Due to its broad functionality and support for numerous file formats, Tika can introduce performance overhead, especially when dealing with large files or volumes of data.
• Complexity for Simple Tasks
  For simple file parsing tasks, using Apache Tika can be overkill due to its comprehensive features and configurations, which can complicate simple workflows.
• Limited Advanced Features
  While Tika excels at extracting basic text and metadata, it lacks some advanced features such extracting complex relational data or handling unstructured data comprehensively.
• Dependency Management
  Integrating Tika into larger projects can sometimes result in challenging dependency management, as it relies on various third-party libraries for parsing different types of content.
• Occasional Parsing Errors
  Like any automated parser, Tika may occasionally encounter issues with complex, malformed, or proprietary file formats, resulting in parsing errors or incomplete content extraction.
