## Important Notes for AI Assistants

1. **Resource Management**: Always use try-with-resources with `CurlResponse`.

2. **Null Safety**: Constructors validate null arguments. Follow this pattern.

3. **Thread Safety**: `RequestProcessor` is single-use per request.

4. **Encoding**: Call `encoding()` before `param()` methods.

    protected static final String JAVABIN = "javabin";

    /** Constant for Kryo serializer type. */
    protected static final String KRYO = "kryo";

    /** ThreadLocal container for Kryo instances to ensure thread safety. */
    protected final ThreadLocal<Kryo> kryoThreadLocal;

    /**
     * Constructs a new DataSerializer.
     * <p>
     * Initializes the ThreadLocal Kryo instances with appropriate configuration.

- **Cross-Language Compatibility:**
Java serialization is inherently Java-centric and does not support cross-language scenarios well.

- **Type Safety:**
Java serialization does not enforce type safety as strictly as some alternatives, potentially leading to runtime errors.

## Decision

We do not use Java serialization.
