MyBATIS features and specs

• Simplicity
  MyBatis is easier to use compared to other ORM tools because it provides a simple and direct approach to database interaction using XML or annotations, making it accessible for developers familiar with SQL.
• Flexibility in SQL
  It allows for complete control over SQL queries, enabling developers to write complex queries and use full SQL syntax without constraints, unlike automated ORM solutions.
• Performance
  Since developers have direct control over SQL statements, the performance can be optimized for specific use cases, potentially reducing the overhead that automated ORM solutions might introduce.
• Mapping
  Offers robust and customizable mapping capabilities between database tables and Java classes, helping in clearly defining how data should be transformed between the system and the data layer.
• Lazy Loading
  Supports lazy loading of related objects, which can improve performance by delaying the fetching of data until it is specifically needed.

Possible disadvantages of MyBATIS

• Manual SQL Management
  The need to manually write and maintain SQL can be cumbersome and error-prone, especially for complex applications with large numbers of queries.
• Lack of Automated Associations
  MyBatis does not inherently manage relationships between entities like some other ORM tools, which requires developers to handle association mappings themselves.
• Limited Abstraction
  Compared to full ORM frameworks, MyBatis offers less abstraction over the database layer, which means developers must handle more of the database logic manually.
• Learning Curve for XML
  While not steep, there is a learning curve involved in configuring MyBatis using XML for those who are more accustomed to purely annotation-driven configuration or other ORM tools.
• Reduced Portability
  Because SQL is database-specific, MyBatis applications might become less portable across different database platforms when relying extensively on custom SQL.

RxJava features and specs

• Asynchronous Programming
  RxJava provides tools for composing asynchronous and event-based programs using observable sequences, making it easier to manage concurrent tasks.
• Composability
  With RxJava, complex asynchronous workflows can be composed of simpler observable sequences, allowing for modular and reusable code.
• Error Handling
  RxJava offers a wide range of operators and try-catch constructs to manage and respond to errors in a resilient manner.
• Rich Operator Set
  RxJava comes with an extensive set of operators that can be used to filter, transform, and combine observable sequences for powerful data manipulation.
• Backpressure Support
  The library provides the ability to handle backpressure, which helps manage situations where producers of data are faster than consumers.

Possible disadvantages of RxJava

• Steep Learning Curve
  RxJava introduces a reactive programming paradigm that can be difficult for developers new to this approach to grasp immediately.
• Complexity in Debugging
  The abstract nature of observables and operators can make it challenging to debug ReactiveX code compared to traditional imperative code.
• Verbose Syntax
  Using RxJava often leads to more verbose code with chains of operators, which can decrease code readability if not well-documented.
• Performance Overhead
  RxJava can introduce some performance overhead due to abstraction layers, which might not be suitable for all performance-critical applications.
• Library Size
  For mobile applications, the size of the RxJava library can be a drawback if minimizing application size is a priority.
