+
+        [TiDB Cloud Dedicated](/tidb-cloud/select-cluster-tier.md#tidb-cloud-dedicated) now supports sinking changefeed data directly to Azure Blob Storage. This feature enables Azure-based users to archive change data efficiently for downstream analytics and long-term retention. It also reduces costs by eliminating the need for intermediate message queues and maintains format compatibility with existing Amazon S3 and Google Cloud Storage (GCS) sinks.
