Anypoint Connector for Confluent Schema Registry (Confluent Schema Registry Connector) enables
interaction with Confluent’s Schema Registry to save and retrieve avro schemas to reduce the size of
an avro message while it transports through the network.

### Compatibility

<table><colgroup><col> <col></colgroup><thead><tr><th>Software</th><th>Version</th></tr></thead><tbody><tr><td><p>Mule runtime engine</p></td><td><p>4.3.0 and later</p></td></tr><tr><td><p>OpenJDK</p></td><td><p>8, 11, and 17</p></td></tr><tr><td><p>Confluent Schema Registry</p></td><td><p>6.0.x</p></td></tr></tbody></table>

## 1.2.0

**August 28, 2026**

### What’s New

- This connector version requires Mule runtime 4.6.22 or later if you’re using Mule 4.6.x, or Mule
  runtime 4.9.9 or later if you’re using Mule 4.9.x. If you prefer not to upgrade your Mule runtime,
  use the connector version released immediately after this one.

- The **Replace id with AVRO schema** operation can now optionally cache parsed Avro schemas so
  that, when the cache is enabled, each schema is parsed only once instead of on every message. The
  cache is disabled by default; enable it in the connector configuration by setting **Maximum size**
  to the number of distinct schemas to retain (0, the default, keeps the cache disabled). Optionally
  set **Time to live** and **Time to live time unit** to evict schemas that go idle. Enabling the
  cache is recommended for high-throughput flows that repeatedly resolve a bounded set of schemas —
  whether a single schema or a fixed group of them — such as streaming Kafka records off one or a
  handful of subjects, where it avoids redundant parsing. Set **Maximum size** to at least the
  number of distinct schemas the flow handles so all of them stay cached. For more information, see
  [Config](https://docs.mulesoft.com/confluent-schema-registry-connector/latest/confluent-schema-registry-connector-reference#config).
