| <table><thead><tr><th>Option Name<th>Description<th>Default Value<tbody><tr><td><code>timeRefIgnored</code><td>Whether to ignore reference tracking of all time types registered in <code>TimeSerializers</code> and subclasses of those types when ref tracking is enabled. If ignored, ref tracking of every time type can be enabled by invoking <code>Fury#registerSerializer(Class, Serializer)</code>. For example, <code>fury.registerSerializer(Date.class, new DateSerializer(fury, true))</code>. Note that enabling ref tracking should happen before serializer codegen of any types which contain time fields. Otherwise, those fields will still skip ref tracking.<td><code>true</code><tr><td><code>compressInt</code><td>Enables or disables int compression for smaller size.<td><code>true</code><tr><td><code>compressLong</code><td>Enables or disables long compression for smaller size.<td><code>true</code><tr><td><code>compressString</code><td>Enables or disables string compression for smaller size.<td><code>false</code><tr><td><code>classLoader</code><td>The classloader should not be updated; Fury caches class metadata. Use <code>LoaderBinding</code> or <code>ThreadSafeFury</code> for classloader updates.<td><code>Thread.currentThread().getContextClassLoader()</code><tr><td><code>compatibleMode</code><td>Type forward/backward compatibility config. Also Related to <code>checkClassVersion</code> config. <code>SCHEMA_CONSISTENT</code>: Class schema must be consistent between serialization peer and deserialization peer. <code>COMPATIBLE</code>: Class schema can be different between serialization peer and deserialization peer. They can add/delete fields independently. <a href=#class-inconsistency-and-class-version-check class="">See more</a>.<td><code>CompatibleMode.SCHEMA_CONSISTENT</code><tr><td><code>checkClassVersion</code><td>Determines whether to check the consistency of the class schema. If enabled, Fury checks, writes, and checks consistency using the <code>classVersionHash</code>. It will be automatically disabled when <code>CompatibleMode#COMPATIBLE</code> is enabled. Disabling is not recommended unless you can ensure the class won't evolve.<td><code>false</code><tr><td><code>checkJdkClassSerializable</code><td>Enables or disables checking of <code>Serializable</code> interface for classes under <code>java.*</code>. If a class under <code>java.*</code> is not <code>Serializable</code>, Fury will throw an <code>UnsupportedOperationException</code>.<td><code>true</code><tr><td><code>registerGuavaTypes</code><td>Whether to pre-register Guava types such as <code>RegularImmutableMap</code>/<code>RegularImmutableList</code>. These types are not public API, but seem pretty stable.<td><code>true</code><tr><td><code>requireClassRegistration</code><td>Disabling may allow unknown classes to be deserialized, potentially causing security risks.<td><code>true</code><tr><td><code>suppressClassRegistrationWarnings</code><td>Whether to suppress class registration warnings. The warnings can be used for security audit, but may be annoying, this suppression will be enabled by default.<td><code>true</code><tr><td><code>metaShareEnabled</code><td>Enables or disables meta share mode.<td><code>true</code> if <code>CompatibleMode.Compatible</code> is set, otherwise false.<tr><td><code>scopedMetaShareEnabled</code><td>Scoped meta share focuses on a single serialization process. Metadata created or identified during this process is exclusive to it and is not shared with by other serializations.<td><code>true</code> if <code>CompatibleMode.Compatible</code> is set, otherwise false.<tr><td><code>metaCompressor</code><td>Set a compressor for meta compression. Note that the passed MetaCompressor should be thread-safe. By default, a <code>Deflater</code> based compressor <code>DeflaterMetaCompressor</code> will be used. Users can pass other compressor such as <code>zstd</code> for better compression rate.<td><code>DeflaterMetaCompressor</code><tr><td><code>deserializeNonexistentClass</code><td>Enables or disables deserialization/skipping of data for non-existent classes.<td><code>true</code> if <code>CompatibleMode.Compatible</code> is set, otherwise false.<tr><td><code>codeGenEnabled</code><td>Disabling may result in faster initial serialization but slower subsequent serializations.<td><code>true</code><tr><td><code>asyncCompilationEnabled</code><td>If enabled, serialization uses interpreter mode first and switches to JIT serialization after async serializer JIT for a class is finished.<td><code>false</code><tr><td><code>scalaOptimizationEnabled</code><td>Enables or disables Scala-specific serialization optimization.<td><code>false</code><tr><td><code>copyRef</code><td>When disabled, the copy performance will be better. But fury deep copy will ignore circular and shared reference. Same reference of an object graph will be copied into different objects in one <code>Fury#copy</code>.<td><code>true</code><tr><td><code>serializeEnumByName</code><td>When Enabled, fury serialize enum by name instead of ordinal.<td><code>false</code></table> |

| <p>In many systems, the schema of a class used for serialization may change over time. For instance, fields within a class |
| may be added or removed. When serialization and deserialization processes use different versions of jars, the schema of |
| the class being deserialized may differ from the one used during serialization.</p> |
| <p>By default, Fury serializes objects using the <code>CompatibleMode.SCHEMA_CONSISTENT</code> mode. This mode assumes that the |
| deserialization process uses the same class schema as the serialization process, minimizing payload overhead. |
| However, if there is a schema inconsistency, deserialization will fail.</p> |
| <p>If the schema is expected to change, to make deserialization succeed, i.e. schema forward/backward compatibility. |
| Users must configure Fury to use <code>CompatibleMode.COMPATIBLE</code>. This can be done using the |
| <code>FuryBuilder#withCompatibleMode(CompatibleMode.COMPATIBLE)</code> method. |
| In this compatible mode, deserialization can handle schema changes such as missing or extra fields, allowing it to |

| <p>This compatible mode involves serializing class metadata into the serialized output. Despite Fury's use of |
| sophisticated compression techniques to minimize overhead, there is still some additional space cost associated with |
| class metadata.</p> |
| <p>To further reduce metadata costs, Fury introduces a class metadata sharing mechanism, which allows the metadata to be |
| sent to the deserialization process only once. For more details, please refer to the <a href=#meta-sharing class="">Meta Sharing</a> |
| section.</p> |
| <h3 class="anchor anchorTargetStickyNavbar_Vzrq" id=smaller-size>Smaller size<a href=#smaller-size class=hash-link aria-label="Direct link to Smaller size" title="Direct link to Smaller size" translate=no></a></h3> |
| <p><code>FuryBuilder#withIntCompressed</code>/<code>FuryBuilder#withLongCompressed</code> can be used to compress int/long for smaller size. |
| Normally compress int is enough.</p> |
| <p>Both compression are enabled by default, if the serialized is not important, for example, you use flatbuffers for |
| serialization before, which doesn't compress anything, then you should disable compression. If your data are all |
| numbers, |
| the compression may bring 80% performance regression.</p> |
| <p>For int compression, fury use 1~5 bytes for encoding. First bit in every byte indicate whether has next byte. if first |
| bit is set, then next byte will be read util first bit of next byte is unset.</p> |
| <p>For long compression, fury support two encoding:</p> |
| <ul> |
| <li class="">Fury SLI(Small long as int) Encoding (<strong>used by default</strong>):<!-- --> |
| <ul> |
| <li class="">If long is in <code>[-1073741824, 1073741823]</code>, encode as 4 bytes int: <code>| little-endian: ((int) value) << 1 |</code></li> |
| <li class="">Otherwise write as 9 bytes: <code>| 0b1 | little-endian 8bytes long |</code></li> |
| </ul> |
| </li> |
| <li class="">Fury PVL(Progressive Variable-length Long) Encoding:<!-- --> |
| <ul> |
| <li class="">First bit in every byte indicate whether has next byte. if first bit is set, then next byte will be read util |
| first bit of next byte is unset.</li> |
| <li class="">Negative number will be converted to positive number by <code>(v << 1) ^ (v >> 63)</code> to reduce cost of small negative |
| numbers.</li> |
| </ul> |
| </li> |
| </ul> |
| <p>If a number are <code>long</code> type, it can't be represented by smaller bytes mostly, the compression won't get good enough |
| result, |
| not worthy compared to performance cost. Maybe you should try to disable long compression if you find it didn't bring |
| much |
| space savings.</p> |

| <p>Fury also provided a <code>org.apache.fury.resolver.AllowListChecker</code> which is allowed/disallowed list based checker to |

| <p>Register class by id will have better performance and smaller space overhead. But in some cases, management for a bunch |

| <p>Fury supports share type metadata (class name, field name, final field type information, etc.) between multiple |
| serializations in a context (ex. TCP connection), and this information will be sent to the peer during the first |
| serialization in the context. Based on this metadata, the peer can rebuild the same deserializer, which avoids |
| transmitting metadata for subsequent serializations and reduces network traffic pressure and supports type |
| forward/backward compatibility automatically.</p> |

| <p>Fury support deserializing non-existent classes, this feature can be enabled |
| by <code>FuryBuilder#deserializeNonexistentClass(true)</code>. When enabled, and metadata sharing enabled, Fury will store |
| the deserialized data of this type in a lazy subclass of Map. By using the lazy map implemented by Fury, the rebalance |
| cost of filling map during deserialization can be avoided, which further improves performance. If this data is sent to |
| another process and the class exists in this process, the data will be deserialized into the object of this type without |
| losing any information.</p> |
| <p>If metadata sharing is not enabled, the new class data will be skipped and an <code>NonexistentSkipClass</code> stub object will be |
| returned.</p> |

| <p>Fury support mapping object from one type to another type.</p> |
| <blockquote> |
| <p>Notes:</p> |
| <ol> |
| <li class="">This mapping will execute a deep copy, all mapped fields are serialized into binary and |
| deserialized from that binary to map into another type.</li> |
| <li class="">All struct types must be registered with same ID, otherwise Fury can not mapping to correct struct type. |
| Be careful when you use <code>Fury#register(Class)</code>, because fury will allocate an auto-grown ID which might be |
| inconsistent if you register classes with different order between Fury instance.</li> |
