Convert Performance Review to Avro

Performance reviews are where we capture how employees are doing, their goals, and feedback. We can grab structured data from these forms, whether they're PDFs or other types of documents.

We pull out key stuff like:

• Who the employee and reviewer are
• When the review covers and happened
• Overall performance score
• Detailed looks at different areas
• What goals were hit and where to improve
• Future goals
• Comments from the employee and manager

This really helps with:

• Keeping tabs on performance
• Planning employee growth
• Making calls on pay and promotions
• Understanding talent and planning the workforce

Getting data out of these reviews makes the whole process smoother. You can spot trends in how people are doing and easily plug all this info into HR systems and analytics tools. It's a game changer for managing performance.

Avro is a row-based data serialization system developed within Apache's Hadoop project. It provides rich data structures and a compact, fast binary data format.

Technical Details

Avro uses JSON for defining data schemas, which are stored with the data. This enables schema evolution while maintaining compatibility. The data itself is stored in a compact binary format.

Advantages

• Compact binary serialization
• Schema definition included with the data
• Support for schema evolution
• Dynamic typing and code generation

Limitations

• Not human-readable without special tools
• Less widely supported than formats like JSON or CSV
• More complex to implement than simpler formats
• Less efficient for columnar queries than Parquet
