Connections contain information about data source access parameters, like the DB host IP address and connection port.
Connections are created using a connector. Connectors contain settings for connecting to popular data sources.
You can create datasets based on connections.
A connector is a driver for connecting and uploading data from a DB, API, or file.
Uses the DataLens connection to request data from the source.
The following types of connectors are available in DataLens:
- CSV file
- MS SQL Server
- Metrica (in direct or API access mode)
- AppMetrica (in direct or API access mode)
Changing connection ranges
When connecting to an external data source (that's not a Yandex.Cloud resource), grant access to the source for the DataLens IP address ranges.
Old ranges valid until December 1, 2020
Transition ranges from October 1 to December 1, 2020
During the transition period, add the new ranges to the current ranges. Starting from December 1, leave only the new ranges.
New ranges as of December 1, 2020
You can configure connection permissions. For more information, see Managing access to DataLens.
