Event Streams provides a
serdes Java library to enable Kafka applications to serialize and deserialize messages using schemas stored in Apicurio Registry in Event Streams. Using the Event Streams
serdes library API, schema versions are automatically downloaded from your Apicurio Registry in Event Streams, checked to see if they are in a disabled or deprecated state, and cached. The schemas are used to serialize messages produced to Kafka and deserialize messages consumed from Kafka.
Schemas downloaded by the Event Streams
serdes library API are cached in memory with a 10 minute expiration period. This means that if a schema is deprecated or disabled, it might take 10 minutes before consuming or producing applications will see the change. To change the expiration period, set the
SchemaRegistryConfig.PROPERTY_SCHEMA_CACHE_REFRESH_RATE configuration property to a new milliseconds value.
