|  | ## Free Memory

#### Synopsis

Frees unused memory. Might be useful after large preprocessing chains with a lot of (now) unused views or even data copies. Can be very useful after the data set was (again) materialized in memory.

#### Description

Cleans up unused memory resources. Might be very useful in combination with the MaterializeDataInMemory operator after large preprocessing trees using lot of views or data copies. Internally, this operator simply invokes a garbage collection from the underlying Java programming language.
