| Rust, Go, JavaScript/TypeScript, C++, C#, Swift, Dart, Scala, Kotlin, or another non-Java Fory implementation. Java defaults to |
| xlang mode with compatible schema evolution, but examples set the mode explicitly so the payload |
| contract is visible in code.</p> |

| <p>Not all Java types have equivalents in other languages. When using xlang mode:</p> |
| <ul> |
| <li class="">Use primitive types (<code>int</code>, <code>long</code>, <code>double</code>, <code>String</code>) for maximum compatibility.</li> |
| <li class="">Use standard collections (<code>List</code>, <code>Map</code>, <code>Set</code>) instead of language-specific collections.</li> |
| <li class="">Use reduced-precision carriers (<code>Float16</code>, <code>BFloat16</code>, <code>Float16List</code>, <code>BFloat16List</code>) for |
| 16-bit float payloads.</li> |
| <li class="">Treat <code>Float16[]</code>, <code>BFloat16[]</code>, <code>Float16List</code>, and <code>BFloat16List</code> as <code>list<T></code> carriers by |
| default; use <code>@ArrayType</code> when the schema must be <code>array<float16></code> or <code>array<bfloat16></code>.</li> |
| <li class="">Avoid Java-specific types like <code>Optional</code>, <code>BigDecimal</code>, and <code>EnumSet</code> unless every target language |
| has an agreed mapping.</li> |

| <p>Java primitive arrays are dense <code>array<T></code> carriers, except plain <code>byte[]</code>, |

| <p>Xlang mode has additional overhead compared to Java native mode:</p> |
| <ul> |
| <li class=""><strong>Type metadata encoding</strong>: Adds extra bytes per type</li> |
| <li class=""><strong>Type resolution</strong>: Requires name/ID lookup during deserialization</li> |
| </ul> |
| <p><strong>For best performance</strong>:</p> |
| <ul> |
| <li class="">Use <strong>ID-based registration</strong> when possible (smaller encoding)</li> |
| <li class=""><strong>Disable reference tracking</strong> if you don't need circular references (<code>withRefTracking(false)</code>)</li> |
| <li class=""><strong>Use native mode</strong> (<code>withXlang(false)</code>) when only Java serialization is needed</li> |
