JDBC Driver for Spark SQL

Build 22.0.8462

CacheLocation

Specifies the path to the cache when caching to a file.

Data Type

string

Default Value

"%APPDATA%\\CData\\SparkSQL Data Provider"

Remarks

The CacheLocation is a simple, file-based cache. The driver uses Java DB, Oracle's distribution of the Derby database. To cache to Java DB, you will need to add the Java DB JAR file to the classpath. The JAR file, derby.jar, is shipped in the JDK and located in the db subfolder of the JDK installation.

If left unspecified, the default location is "%APPDATA%\\CData\\SparkSQL Data Provider" with %APPDATA% being set to the user's configuration directory:

Platform %APPDATA%
Windows The value of the APPDATA environment variable
Mac ~/Library/Application Support
Linux ~/.config
