Reading delta data from the filesystem

Last updated: 8/27/2026

Configure tDeltaLakeInput to read the different snapshots of the data about US flights so that your Job can then easily calculate the evolution of the flights.

Each snapshot got a version when they were written in the Delta Lake dataset to be used.

Procedure

Configure the storage configuration component to be used to provide the connection information to your filesystem. In this example, it is a tS3Configuration
Double-click the tDeltaLakeInput component labeled flights_latest_version to open its Component view.
Select the Select a storage configuration component check box to reuse the connection information defined in tS3Configuration.
Click Edit schema to open the schema editor. In this editor, define the schema of the input data.
In the Folder/File field, enter the directory where the flight dataset is stored, in the S3 bucket specified in tS3Configuration.
Do the same to configure the other tDeltaLakeInput component but select the Specify time travel version check box and enter 0 in double quotation marks in the displayed Version field, meaning, in this scenario, to read the first version of the data about US flights.
Without using the time travel feature, tDeltaLakeInput reads the latest snapshot of your data; the time travel feature allows you to specify the snapshot to be read.
