### What issue do you find in Pulsar docs? Regarding schema evolution, the [Pulsar documentation](https://pulsar.apache.org/docs/schema-evolution-compatibility#how-does-pulsar-support-schema-evolution) states the following: > **How does Pulsar support schema evolution?** > > When a producer/consumer/reader connects to a broker, the broker deploys the schema compatibility checker configured by _schemaRegistryCompatibilityCheckers_ to enforce schema compatibility check. What exactly is "schemaRegistryCompatibilityCheckers" and where is it configured? The term seems to appear out of the blue without any context. It isn't referenced anywhere else in the documentation as far as I can see. If I search for the term online all I find is a [reference](https://github.com/apache/pulsar/blob/master/pulsar-broker/src/main/java/org/apache/pulsar/broker/service/schema/SchemaRegistryService.java#L45) in the Pulsar codebase (specifically a parameter to the SchemaRegistryService.create method): static SchemaRegistryService create(SchemaStorage schemaStorage, Set<String> schemaRegistryCompatibilityCheckers) { The documentation doesn't appear to be suggesting that I should be calling this method, so what does it mean? ### What is your suggestion? The documentation should make clear what exactly "schemaRegistryCompatibilityCheckers" is and where it is defined/configured. A code example would help enormously. ### Do you have any references? N/A ### Would you like to fix this issue? I would if I knew the answer. ### Note - [X] I have researched my question. -- This is an automated message from the Apache Git Service.
