# Tableflow Concepts in Confluent Cloud Confluent Tableflow is a Confluent Cloud service that enables you to expose Kafka topics as Apache Iceberg™ or Delta Lake tables. Tableflow automatically materializes Kafka topics into Iceberg or Delta Lake tables in your cloud storage. These tables can be consumed as external read-only Iceberg or Delta Lake tables (Preview). Tableflow integrates with [catalog services](../how-to-guides/catalog-integration/overview.md#cloud-tableflow-how-to-guides-catalog-integration), like AWS Glue Data Catalog, Iceberg REST catalog (IRC), and Snowflake Open Catalog. You can query Tableflow tables by using Confluent Cloud for Apache Flink® or other [query engines](../how-to-guides/query-engines/overview.md#cloud-tableflow-how-to-guides-query-engines), like Snowflake and Trino. Tableflow concepts include: - [Billing](tableflow-billing.md#cloud-tableflow-billing): Learn about the billing model for Tableflow. - [Materialize Change Data Capture (CDC) Streams](materialize-cdc.md#cloud-tableflow-materialize-cdc): Learn how to materialize CDC streams into Iceberg or Delta Lake tables. - [Schemas](tableflow-schemas.md#cloud-tableflow-schemas): Learn about schemas for Tableflow tables. - [Storage](tableflow-storage.md#tableflow-storage): Learn about storage options for Tableflow tables. ## Related content - [Quick Start Using Confluent Storage](../get-started/quick-start-managed-storage.md#cloud-tableflow-quick-start-managed-storage) - [Quick Start Using Your Storage and AWS Glue](../get-started/quick-start-custom-storage-glue.md#cloud-tableflow-quick-start) - [Quick Start with Delta Lake Tables](../get-started/quick-start-delta-lake.md#cloud-tableflow-quick-start-delta-lake) #### NOTE This website includes content developed at the [Apache Software Foundation](https://www.apache.org/) under the terms of the [Apache License v2](https://www.apache.org/licenses/LICENSE-2.0.html).
