Hello, I had a question about the FileSource in Flink 1.14 <https://nightlies.apache.org/flink/flink-docs-master/api/java/org/apache/flink/connector/file/src/FileSource.html> .
Considering FileSource is set to read from a remote GCS URL, I could read and understand that the FileEnumerator is actually responsible for discovering the files under the URL. However, how does the FileSource, and thus the FileEnumerator, generate the splits when a remote URL is used ? Does it: 1. download all the files eagerly and then generate the splits ?, or 2. only downloads and generates the splits when the source reader asks for splits ?, or 3. doesn't download but only streams the data from the remote as required ? Would be great if somebody could help me out. Thanks ! *Regards,* *Meghajit*
