Redis Connections

Note

This feature may not be available in all product editions. For more information on available features, see Compare Editions.

Redis (Remote Dictionary Server), is a fast, open-source, in-memory key-value data store for use as a database, cache, message broker, and queue. For more information, see https://redis.io/.

Tip

This connection is in early preview. It is read-only and available only in SaaS product editions. For more information on early previews, see Early Preview Connection Types.

Limitations and Requirements

Note

During normal selection or import of an entire table, you may encounter an error indicating a problem with a specific column. Since some tables require filtering based on a particular column, data from them can only be ingested using custom SQL statements. In this case, the problematic column can be used as a filter in the WHERE clause of a custom SQL statement to ingest the table.

  • For more information, please consult the CData driver documentation for the specific table.

  • For more information on using custom SQL, see Create Dataset with SQL.

Note

For filtering date columns, this connection type supports a set of literal functions on dates. You can use these to reduce the volume of data extracted from the database using a custom SQL query. For more information, see the pg_dateliteralfunctions.htm page in the driver documentation for this connection type.

  • Only password-based authentication is supported.
