The Designer Cloud Powered by Trifacta® platform can be configured to read and write data from multiple environments at the same time. This page provides information on the supported options.
After you have configured the base storage layer and access and browsing capabilities, you cannot switch them for your Alteryx deployment.
Definitions
Base Storage Layer:
The base storage layer defines where job results are written by default.
NOTE: The base storage layer should be enabled and configured during initial installation. After the base storage layer has been configured, it cannot be switched to another environment.
Tip: The Designer Cloud Powered by Trifacta platform can enable connectivity to both S3 and HDFS at the same time. Note that webapp.storageProtocol=s3 should still be specified to write results to S3.
Optionally, you can enable access and the ability to browse your S3 datastore.
JDBC Sources:
Independent of these storage options, you can access database table data through JDBC datastores. See Enable Relational Connections.
HDFS Only
Base Storage Layer: HDFS
Access and Browse data - S3: Off
Notes:
The default configuration, this deployment should be used for most on-premise Hadoop environments. In this case, the Designer Cloud Powered by Trifacta platform only has access to HDFS and Hive as sources on a single Hadoop cluster.
Hybrid Hadoop-based Deployment
Base Storage Layer: HDFS
Access and Browse data - S3: On
Notes:
This deployment is recommended for the following:
- On-premises Hadoop clusters that require access to remote S3 data
- Hadoop clusters hosted in the cloud that require access to remote S3 data and want to continue to use HDFS as an output location
In this scenario, the Designer Cloud Powered by Trifacta platform has access to HDFS and Hive data on the same cluster, as well as access to the remote S3 buckets that have been enabled for the platform.
- HDFS remains the output location for all job results, profiles, and uploads.
