Advanced Data Format Management - Comprehensive data handling covering TOON encoding, JSON/YAML optimization, serialization patterns, and data validation for performance-critical applications.
Core Capabilities:
  • TOON Encoding: 40-60% token reduction vs JSON for LLM communication
  • JSON/YAML Optimization: Efficient serialization and parsing patterns
  • Data Validation: Schema validation, type checking, error handling
  • Format Conversion: Seamless transformation between data formats
  • Performance: Optimized data structures and caching strategies
  • Schema Management: Dynamic schema generation and evolution
When to Use:
  • Optimizing data transmission to LLMs within token budgets
  • High-performance serialization/deserialization
  • Schema validation and data integrity
  • Format conversion and data transformation
  • Large dataset processing and optimization
Quick Start:
Create a TOONEncoder instance and call encode with a dictionary containing user and age fields to compress the data. The encoded result achieves 40-60% token reduction. Call decode to restore the original data structure.
Create a JSONOptimizer instance and call serialize_fast with a large dataset to achieve ultra-fast JSON processing.
Create a DataValidator instance and call create_schema with a dictionary defining name as a required string type. Call validate with the data and schema to check validity.

Basic Implementation

基础实现

TOON Encoding for LLM Optimization:
Create a TOONEncoder instance. Define data with user object containing id, name, active boolean, and created datetime, plus permissions array. Call encode to compress and decode to restore. Compare sizes to verify reduction.
Fast JSON Processing:
Create a JSONOptimizer instance. Call serialize_fast to get bytes and deserialize_fast to parse. Use compress_schema with a type object and properties definition to optimize repeated validation.
Data Validation:
Create a DataValidator instance. Define user_schema with username requiring string type, minimum length 3, email requiring email type, and age as optional integer with minimum value 13. Call validate with user_data and schema, then check result for valid status, sanitized_data, or errors list.
面向LLM优化的TOON编码：
创建TOONEncoder实例。定义包含id、name、active布尔值、created时间戳的user对象，以及permissions数组的数据。调用encode方法压缩数据，调用decode方法恢复数据。对比体积以验证压缩效果。
快速JSON处理：
创建JSONOptimizer实例。调用serialize_fast方法获取字节数据，调用deserialize_fast方法解析数据。使用compress_schema方法传入类型对象与属性定义，以优化重复验证操作。
数据验证：
创建DataValidator实例。定义user_schema，其中username为必填字符串类型（最小长度3），email为必填邮箱类型，age为可选整数类型（最小值13）。调用validate方法传入user_data与架构，然后检查结果中的valid状态、sanitized_data或errors列表。

Common Use Cases

常见用例

API Response Optimization:
Create a function to optimize API responses for LLM consumption by encoding data with TOONEncoder. Create a corresponding function to parse optimized responses by decoding TOON data back to dictionary.
Configuration Management:
Create a YAMLOptimizer instance and call load_fast with a config file path. Call merge_configs with base_config, env_config, and user_config for multi-file merging.
Large Dataset Processing:
Create a StreamProcessor with chunk_size of 8192. Define a process_item function that handles each item. Call process_json_stream with the file path and callback to process large JSON files without loading into memory.
API响应优化：
创建函数，通过TOONEncoder编码数据，优化API响应以适配LLM消费。创建对应的解析函数，将TOON数据解码回字典格式。
配置管理：
创建YAMLOptimizer实例，调用load_fast方法加载配置文件路径。调用merge_configs方法合并base_config、env_config与user_config多文件配置。
大型数据集处理：
创建chunk_size为8192的StreamProcessor实例。定义process_item函数处理每个数据项。调用process_json_stream方法传入文件路径与回调函数，无需将整个大型JSON文件加载到内存即可进行处理。
