+# JSON Compatibility
+
+Comet can evaluate JSON expressions (`get_json_object`, `from_json`, `to_json`,
+`json_array_length`) two ways:
+
+- **Codegen dispatcher (default):** Spark's own `doGenCode` for the expression
+ runs inside the Comet pipeline (via Comet's Arrow-direct codegen dispatcher),
+ giving byte-exact compatibility with Spark at the cost of a JNI roundtrip per
+ batch. This rides the codegen dispatcher
+ (`spark.comet.exec.scalaUDF.codegen.enabled`, enabled by default); if the
+ dispatcher is disabled, the operator falls back to Spark.
+- **Native (rust) path:** the native DataFusion implementation. Faster, but has
+ known compatibility gaps with Spark on certain inputs, so it is **opt-in per
+ expression** via the expression's `allowIncompatible` config. Any expression
or
+ input case with no native implementation falls back to the codegen
dispatcher.
+
+## Expression coverage
+
+| SQL | Native (rust) path
| Opt-in config
|
+| ------------------- |
----------------------------------------------------------------------------------------------
| ------------------------------------------------------------ |
+| `get_json_object` | Supported, with gaps on single-quoted JSON and
unescaped control characters |
`spark.comet.expression.GetJsonObject.allowIncompatible` |
+| `from_json` | Supported with restrictions (PERMISSIVE mode only,
simple schema types only) |
`spark.comet.expression.JsonToStructs.allowIncompatible` |
+| `to_json` | Supported for struct inputs only, no options
|
`spark.comet.expression.StructsToJson.allowIncompatible` |
+| `json_array_length` | Supported, with gaps on single-quoted JSON, unescaped
control characters, and trailing content |
`spark.comet.expression.LengthOfJsonArray.allowIncompatible` |
+
+When the native path is enabled but an expression or input case has no native
+implementation (for example `to_json` with map or array inputs, or `from_json`
+with an unsupported schema), Comet falls back to the codegen dispatcher for
that
+case.
+
+## When to use the native path
+
+- You want the faster native path and your inputs avoid the known compatibility
+ gaps above.
+- Enable it per expression, for example
+ `spark.comet.expression.GetJsonObject.allowIncompatible=true`. Cases the
native path
+ does not cover still fall back to the codegen dispatcher.

-<h2>Round-Robin Partitioning<a class="headerlink"
href="#round-robin-partitioning" title="Link to this heading">#</a></h2>
-<p>Comet’s native shuffle implementation of round-robin partitioning (<code
class="docutils literal notranslate"><span
class="pre">df.repartition(n)</span></code>) is not compatible with
-Spark’s implementation and is disabled by default. It can be enabled by setting
-<code class="docutils literal notranslate"><span
class="pre">spark.comet.native.shuffle.partitioning.roundrobin.enabled=true</span></code>.</p>
-<p><strong>Why the incompatibility exists:</strong></p>
-<p>Spark’s round-robin partitioning sorts rows by their binary <code
class="docutils literal notranslate"><span class="pre">UnsafeRow</span></code>
representation before assigning them to
-partitions. This ensures deterministic output for fault tolerance (task
retries produce identical results).
-Comet uses Arrow format internally, which has a completely different binary
layout than <code class="docutils literal notranslate"><span
class="pre">UnsafeRow</span></code>, making it
-impossible to match Spark’s exact partition assignments.</p>
-<p><strong>Comet’s approach:</strong></p>
-<p>Instead of true round-robin assignment, Comet implements round-robin as
hash partitioning on ALL columns. This
-achieves the same semantic goals:</p>
+<section id="when-to-use-the-native-path">
+<h2>When to use the native path<a class="headerlink"
href="#when-to-use-the-native-path" title="Link to this heading">#</a></h2>
<ul class="simple">
-<li><p><strong>Even distribution</strong>: Rows are distributed evenly across
partitions (as long as the hash varies sufficiently -
-in some cases there could be skew)</p></li>
-<li><p><strong>Deterministic</strong>: Same input always produces the same
partition assignments (important for fault tolerance)</p></li>
-<li><p><strong>No semantic grouping</strong>: Unlike hash partitioning on
specific columns, this doesn’t group related rows together</p></li>
+<li><p>You want the faster native path and your inputs avoid the known
compatibility
+gaps above.</p></li>
+<li><p>Enable it per expression, for example
+<code class="docutils literal notranslate"><span

Cases the native path

</ul>
-<p>The only difference is that Comet’s partition assignments will differ from
Spark’s. When results are sorted,

ordering.</p>
