Through the Import Data page, you can upload datasets or select datasets from sources that are stored on connected datastores. From the Library page, click Import Data.
Import Data page
NOTE: For file-based sources, expects that each row of data in the import file is terminated with a consistent newline character, including the last one in the file.
File and path limitations:
:) cannot appear in a filename or a file path.
.) or underscore(
NOTE: Compressed files are recognized and can be imported based on their file extensions.
Upload: can also load files from your local file system.
Tip: You can drag and drop files from your desktop to to upload them.
NOTE: You can upload a file up to 1 GB in size.
NOTE: When you upload an updated version of a previously uploaded file, the new file is stored as a separate upload altogether. In your flow, you must swap out the old dataset to point to the new one.
HDFS: If connected to a Hadoop cluster, you can select file(s) or folders to import. See HDFS Browser.
Hive: If connected to a Hive instance, you can load datasets from individual tables within the set of Hive databases. See Hive Browser.
S3: If connected to an S3 instance, you can browse your S3 buckets to select source files.
Tip: For HDFS and S3, you can select folders, which selects each file within the directory as a separate dataset.
See S3 Browser.
Redshift: If connected to an S3 datawarehouse, you can import source from the connected database. See Redshift Browser.
WASB: If enabled, you can import data into your Azure deployment from WASB. For more information, see WASB Browser.
ADL: If enabled, you can import data into your Azure deployment from ADLS Gen1. See ADLS Gen1 Browser.
ADLS Gen2: If enabled, you can import data into your Azure deployment from ADLS Gen1. See ADLS Gen2 Browser.
Alation: If connected to Alation, you can search for and import Hive tables as imported datasets. For more information, see Using Alation.
Waterline: If connected to Waterline, you can search for and import datasets through the data catalog. For more information, Using Waterline.
Databases: If connected to a relational datastore, you can load tables or views from your database. See Database Browser.
NOTE: For long-loading relational sources, you can monitor progress through each stage of ingestion. After these sources are ingested, subsequent steps to import and wrangle the data may be faster.For more information, see Configure JDBC Ingestion.
For more information, see Overview of Job Monitoring.
For more information on the supported input formats, see Supported File Formats.
New/Edit: Click to create or edit a connection. By default, the displayed connections support import.
Search: Enter a search term to locate a specific connection.
NOTE: This feature may be disabled in your environment. For more information, contact your .
See Create Connection Window.
When you have found your source directory or file:
You can hover over the name of a file to preview its contents.
NOTE: Preview may not be available for some sources, such as Parquet.
Click the Plus icon next to the directory or filename to add it as a dataset.
Tip: You can import multiple datasets at the same time. See below.
Excel files: Click the Plus icon next to the parent workbook to add all of the worksheets as a single dataset, or you can add individual sheets as individual datasets. See Import Excel Data.
If custom SQL query is enabled, you can click Create Dataset with SQL to enter a customized SQL statement to pre-filter the table within the database to include only the rows and columns of interest.
Through this interface, it is possible to enter SQL statements that can delete data, change table schemas, or otherwise corrupt the targeted database. Please use this feature with caution.
For more information, see Create Dataset with SQL.
If parameterization has been enabled, you can apply parameters to the source paths of your datasets to capture a wider set of sources. Click Create Dataset with Parameters. See Create Dataset with Parameters.
When a dataset has been selected, the following fields appear on the right side of the screen. Modify as needed:
Dataset Description: You may add an optional description that provides additional detail about the dataset. This information is visible in some areas of the interface.
Tip: Click the Eye icon to inspect the contents of the dataset prior to importing.
You can select a single dataset or multiple datasets for import.
You can modify settings used during import for individual files. In the card for an individual dataset, click Edit Settings.
NOTE: In some cases, there may be discrepancies between row counts in the previewed data versus the data grid after the dataset has been imported, due to rounding in row counts performed in the preview.
For more information on supported encodings, see Configure Global File Encoding Type.
Remove special characters from column names: When selected, characters that are not alphanumeric or underscores are stripped, and space characters are converted to underscores.
Tip: This feature matches the column renaming behavior in Release 5.0 and earlier.
For more information, see Sanitize Column Names.
To enable , select the Infer column data types checkbox.
Tip: To see the effects of , you can toggle the checkbox and review data type listed at the top of individual columns. To override an individual column's data type, click the data type name and select a new value.
If you have selected a single dataset for import:
You can import multiple datasets from multiple sources at the same time. In the Import Data page, continue selecting sources, and additional dataset cards are added to the right panel.
NOTE: If you are importing from multiple files at the same time, the files are not necessarily read in a regular or predictable order.
NOTE: When you import a dataset with parameters from multiple files, only the first matching file is displayed in the right panel.
In the right panel, you can see a preview of each dataset and make changes as needed.
Import Multiple Datasets
If you have selected multiple datasets for import:
Create or select the flow to which to add them:
