-------------------------------------------
Summary: Fix ON_CDC_CACHE_WARMED_UP not fired when schema
publisher fails
Key: CASSSIDECAR-459
URL: https://issues.apache.org/jira/browse/CASSSIDECAR-459
Project: Sidecar for Apache Cassandra
Issue Type: Task
Reporter: Jyothsna Konisa
CdcPublisher.scheduleDecision() requires both isInitialized and
cdcCacheWarmedUp before starting CDC consumers. A transient Kafka or
schema-registry failure in CachingSchemaStore.onSchemaChanged() would propagate
out of the warm-up callback, preventing ON_CDC_CACHE_WARMED_UP from ever firing
and leaving cdcCacheWarmedUp permanently false — CDC would never start. The fix
wraps loadPublisher() and publishSchemas() in try/catch in both the
initialisation and schema-change paths, logging failures as non-fatal errors so
the warm-up sequence always completes.
