Talend Data Preparation
If you are a subscription user, nothing is saved directly on your computer. All the data from your datasets and preparations is stored remotely on the Talend Data Preparation server.
When using the live dataset feature, or preparing data stored on a database or a Hadoop file system (HDFS,) the sample data is cached on the Talend Data Preparation server for one hour.
