+
+Redis Cloud now supports [Redis Data Integration (RDI)]({{<relref "integrate/redis-data-integration">}}), a fast and simple way to bring your data into Redis from other types of primary databases.
+
+A relational database usually handles queries much more slowly than a Redis database. If your application uses a relational database and makes many more reads than writes (which is the typical case) then you can improve performance by using Redis as a cache to handle the read queries quickly. Redis Cloud uses [ingest]({{<relref "/integrate/redis-data-integration/">}}) to help you offload all read queries from the application database to Redis automatically.
+
+Using a data pipeline lets you have a cache that is always ready for queries. RDI Data pipelines ensure that any changes made to your primary database are captured in your Redis cache within a few seconds, preventing cache misses and stale data within the cache. 
+
+RDI helps Redis customers sync Redis Cloud with live data from their primary databases to:
+- Meet the required speed and scale of read queries and provide an excellent and predictable user experience.
+- Save resources and time when building pipelines and coding data transformations.
+- Reduce the total cost of ownership by saving money on expensive database read replicas.
+
+Using RDI with Redis Cloud simplifies managing your data integration pipeline. No need to worry about hardware or underlying infrastructure, as Redis Cloud manages that for you. Creating the data flow from source to target is much easier, and there are validations in place to reduce errors.
+
+## Data pipeline architecture
+
+A RDI data pipeline sits between your source database and your target Redis database. Initially, the pipeline reads all of the data and imports it into the target database during the *initial cache loading* phase. After this initial sync is complete, the data pipeline enters the *change streaming* phase, where changes are captured as they happen. Changes in the source database are added to the target within a few seconds of capture. The data pipeline translates relational database rows to Redis hashes or JSON documents. 
+
+For more info on how RDI works, see [RDI Architecture]({{<relref "/integrate/redis-data-integration/architecture">}}).
+
+### Pipeline security
+
+Data pipelines are set up to ensure a high level of data security. Source database credentials and TLS secrets are stored in AWS secret manager and shared using the AWS Secret Manager CSI driver for secrets. See [Share source database credentials]({{<relref "/operate/rc/databases/rdi/setup#share-source-database-credentials">}}) to learn how to share your source database credentials and TLS certificates with Redis Cloud.
+
+Connections to the source database use Java Database Connectivity (JDBC) through [AWS PrivateLink](https://aws.amazon.com/privatelink/), ensuring that the data pipeline is only exposed to the specific database endpoint. See [Set up connectivity]({{<relref "/operate/rc/databases/rdi/setup#set-up-connectivity">}}) to learn how to connect your PrivateLink to the Redis Cloud VPC.
+
+RDI encrypts all network connections with TLS. The pipeline will process data from the source database in-memory and write it to the target database using a TLS connection. There are no external connections to your data pipeline except from Redis Cloud management services.
+
+## Prerequisites
+
+Before you can create a data pipeline, you must have:
+
+- A [Redis Cloud Pro database]({{< relref "/operate/rc/databases/create-database/create-pro-database-new" >}}) hosted on Amazon Web Services (AWS)
+- One supported source database, also hosted on AWS and connected to [AWS PrivateLink](https://aws.amazon.com/privatelink/):
+    - MySQL
+    - Oracle
+    - SQL Server
+    - PostgreSQL
+    - mariaDB
+    - Aurora
+
+{{< note >}}
+Please be aware of the following limitations:
+
+- The target database must be a Redis Cloud Pro database hosted on Amazon Web Services (AWS). Redis Cloud Essentials databases and databases hosted on Google Cloud do not support Data Integration.
+- Source databases must also be hosted on AWS.
+- One source database can only be synced to one target database.
+{{< /note >}} 
+
+## Get started
+
+To create a new data pipeline, you need to:
+
+1. [Prepare your source database]({{<relref "/operate/rc/databases/rdi/setup">}}) and any associated credentials.
+2. [Provision data pipeline infrastructure]({{<relref "/operate/rc/databases/rdi/provision">}}) and troubleshoot errors.
+3. [Define the data pipeline]({{<relref "/operate/rc/databases/rdi/define">}}) by selecting which tables to sync.
+
+Once your data pipeline is defined, you can [view and edit]({{<relref "/operate/rc/databases/rdi/view-edit">}}) it.

+
+After you have [provisioned your data pipeline]({{<relref "/operate/rc/databases/rdi/provision]">}}), you need to define it. You will select the database schemas and columns that you want to import and synchronize with your primary database.
+
+## Configure a new pipeline
+
+1. In the [Redis Cloud console](https://cloud.redis.io/), go to your target database and select the **Data Pipeline** tab. If your pipeline is already provisioned, select **Complete setup** to go to the **Pipeline definition** section.
+1. For the **Configure a new pipeline** option, select the Redis data type to write keys to the target. You can choose **Hash** or **JSON**. 
+
+    Select **Continue**. 
+1. Select the Schema and Tables you want to migrate to the target database from the **Source data selection** list. You can select any number of columns from a table. 
+
+    If any tables are missing a unique constraint, the **Missing unique constraint** list will appear. Select the columns that define a unique constraint for those tables from the list.
+
+    Select **Add schema** to add additional database schemas. 
+
+    Select **Delete** to delete a schema. You must have at least one schema to continue.
+
+    After you've selected the schemas and tables you want to sync, select **Continue**.
+
+1. Review the tables you selected in the **Summary**. If everything looks correct, select **Start ingest** to start ingesting data from your source database. 
+
+At this point, the data pipeline will ingest data from the source database to your target Redis database. This process will take time, especially if you have a lot of records in your source database. 
+
+After this initial sync is complete, the data pipeline enters the *change streaming* phase, where changes are captured as they happen. Changes in the source database are added to the target within a few seconds of capture. 
+
+You can view the status of your data pipeline in the **Data pipeline** tab of your database. See [View and edit data pipeline]({{<relref "/operate/rc/databases/rdi/view-edit">}}) to learn more.

+
+After you have [prepared your source database]({{<relref "/operate/rc/databases/rdi/setup">}}) and connection information, you can set up your new pipeline.
+
+1. In the [Redis Cloud console](https://cloud.redis.io/), go to your target database and select the **Data Pipeline** tab.
+1. Select **Start pipeline setup**. 
+1. Enter a **Pipeline name**. This pipeline name will be the prefix to all keys generated by this pipeline in the target database.
+1. Enter the **Deployment CIDR** for your pipeline, or use the one generated for you. This CIDR should not conflict with your apps or other databases.
+1. In the **Connectivity** section, enter the **PrivateLink service name** of the [PrivateLink connected to your source database]({{< relref "/operate/rc/databases/rdi/setup#set-up-connectivity" >}}).
+1. Enter your database details. This depends on your database type, and includes:
+    - **Port**: The database's port
+    - **Database**: Your database's name, or the root database *(PostgresSQL, Oracle only)*; or a comma-separated list of one or more databases you want to connect to *(SQL Server only)*
+    - **Database Server ID**: Unique ID for the replication client. Leave as default if you don't use replication *(mySQL and mariaDB only)*
+    - **PDB**: Name of the Oracle pluggable database *(Oracle only)*
+1. Enter the ARN of your [database credentials secret]({{< relref "/operate/rc/databases/rdi/setup#share-source-database-credentials" >}}) in the **Source database secrets ARN** field.
+1. Select **Start pipeline setup**.
+
+At this point, Redis Cloud will provision the pipeline infrastructure that will allow you to define your data pipeline. 
+
+Pipelines are provisioned in the background. You aren't allowed to make changes to your data pipeline or to your database during provisioning. This process will take a long time, so you can close the window and come back later.
+
+See [Pipeline provisioning errors](#errors) to view a list of errors that can occur at this point.
+
+When your pipeline is provisioned, select **Complete setup**. You will then [define your data pipeline]({{<relref "/operate/rc/databases/rdi/define">}}).

+
+## Create new data pipeline
+
+1. In the [Redis Cloud console](https://cloud.redis.io/), go to your target database and select the **Data Pipeline** tab.
+1. Select **Create data pipeline**.
+1. Select your source database type. The following database types are supported:
+    - MySQL
+    - Oracle
+    - SQL Server
+    - PostgreSQL
+1. If you know the size of your source database, enter it into the **Source dataset size** field.
+
+## Prepare source database
+
+Before using the pipeline, you must first prepare your source database to use the Debezium connector for change data capture (CDC).
+
+See [Prepare source databases]({{<relref "/integrate/redis-data-integration/data-pipelines/prepare-dbs/">}}) to find steps for your database type.
+
+See the [RDI architecture overview]({{< relref "/integrate/redis-data-integration/architecture#overview" >}}) for more information about CDC.
+
+## Share source database credentials
+
+You need to share your source database credentials and certificates in an Amazon secret with Redis Cloud so that the pipeline can connect to your database.
+
+In the [AWS Management Console](https://console.aws.amazon.com/), use the **Services** menu to locate and select **Security, Identity, and Compliance** > **Secrets Manager**. [Create a secret](https://docs.aws.amazon.com/secretsmanager/latest/userguide/create_secret.html) of type **Other type of secret** with the following key/value fields:
+
+- `username`: Database username
+- `password`: Database password
+- `server_certificate`: Server certificate in PEM format *(TLS only)*
+- `client_certificate`: [X.509 client certificate](https://en.wikipedia.org/wiki/X.509) or chain in PEM format *(mTLS only)*
+- `client_certificate_key`: Key for the client certificate or chain in PEM format *(mTLS only)*
+- `client_certificate_passphrase`: Passphrase or password for the client certificate or chain in PEM format *(mTLS only)*
+
+{{<note>}}
+If your source database has TLS or mTLS enabled, we recommend that you enter the `server_certificate`, `client_certificate`, and `client_certificate_key` into the secret editor using the **Key/Value** input method instead of the **JSON** input method. Pasting directly into the JSON editor may cause an error. 
+{{</note>}}
+
+After you store this secret, you can view and copy the [Amazon Resource Name (ARN)](https://docs.aws.amazon.com/secretsmanager/latest/userguide/reference_iam-permissions.html#iam-resources) of your secret on the secret details page. 
+
+## Set up connectivity
+
+To expose your source database to Redis, you need to add Redis Cloud as an Allowed Principal on the [AWS PrivateLink VPC permissions](https://docs.aws.amazon.com/vpc/latest/privatelink/configure-endpoint-service.html#add-remove-permissions) for the PrivateLink connected to your source database.
+
+1. Copy the Amazon Resource Name (ARN) provided in the **Setup connectivity** section.
+1. Open the [Amazon VPC console](https://console.aws.amazon.com/vpc/) and select **Endpoint services**.
+1. Navigate to **Allow principals** tab.
+1. Add the Redis Cloud ARN and choose **Allow principals**.
+1. Copy your PrivateLink service name for later.
+
+For more details on AWS PrivateLink, see [Share your services through AWS PrivateLink](https://docs.aws.amazon.com/vpc/latest/privatelink/privatelink-share-your-services.html).
+
+
+## Next steps
+
+After you have set up your source database and prepared connectivity and credentials, select **Start pipeline setup** to [provision data pipeline infrastructure]({{<relref "/operate/rc/databases/rdi/provision">}}).

+
+You can use the **Data pipeline** tab in your database to view and edit it.
+
+The **Data pipeline** tab gives an overview of your data pipeline and lets you view your data stream metrics. 
+
+## Edit data pipeline
+
+To change the data you want to ingest from the data pipeline:
+
+1. From the **Data pipeline** tab, select **Edit**.
+
+1. For the **Configure a new pipeline** option, select the Redis data type to write keys to the target. You can choose **Hash** or **JSON**. 
+
+    Select **Continue**.
+
+1. Select the schema and tables you want to migrate to the target database from the **Source data selection** list. You can select any number of columns from a table. 
+
+    If any tables are missing a unique constraint, the **Missing unique constraint** list will appear. Select the columns that define a unique constraint for those tables from the list.
+
+    Select **Add schema** to add additional database schema.
+
+    Select **Delete** to delete a schema. You must have at least one schema to continue.
+
+    After you've selected the schemas and tables you want to sync, select **Continue**.
+
+1. Review the tables you selected in the **Summary** and select how you want to update the data pipeline:
+
+    - **Apply to new data changes only**: The data pipeline will only synchronize new updates to the schema and tables selected. The data pipeline will not ingest any data from new schemas or tables that are selected.
+    - **Reset pipeline (re-process all data)**: The data pipeline will re-ingest all of the selected data.
+    - **Flush cached data and reset pipeline**: The data pipeline will flush the target Redis database, and then re-ingest all of the selected data from the source database.
+
+1. Select **Apply changes**.
+
+At this point, the data pipeline will apply the changes. If you selected **Reset pipeline** or **Flush cached data and reset pipeline**, the data pipeline will ingest data from the source database to the target database. After this initial sync is complete, the data pipeline enters the *change streaming* phase, where changes are captured as they happen.
+
+If you selected **Apply to new data changes only**, the data pipeline will enter the *change streaming* phase without ingesting the data.
+
+## Reset data pipeline
+
+Resetting the data pipeline creates a new baseline snapshot from the current state of your source database, and re-processes the data from the source database to the target Redis database. You may want to reset the pipeline if the source and target databases were disconnected or you made large changes to the data pipeline.
+
+To reset the data pipeline and restart the ingest process:
+
+1. From the **Data pipeline** tab, select **More actions**, and then **Reset pipeline**.
+
+1. If you want to flush the database, check **Flush target database**. 
+
+1. Select **Reset data pipeline**.
+
+At this point, the data pipeline will re-ingest data from the source database to your target Redis database. 
+
+## Stop and restart data pipeline
+
+To stop the data pipeline from synchronizing new data:
+
+1. From the **Data pipeline** tab, select **More actions**, and then **Stop pipeline**.
+
+1. Select **Stop data pipeline** to confirm.
+
+Stopping the data pipeline will suspend data processing. To restart the pipeline from the **Data pipeline** tab, select **More actions**, and then **Start pipeline**.
+
+## Delete pipeline
+
+To delete the data pipeline:
+
+1. From the **Data pipeline** tab, select **More actions**, and then **Delete pipeline**.
+
+1. Select **Delete data pipeline** to confirm.
+
+Deleted data pipelines cannot be recovered.
