Ruben Q L updated CALCITE-4193: ------------------------------- Description: Sometimes we need to sort a big volume of data which does not fit into memory. In this situation EnumerableSort will cause an OutOfMemoryError. The solution for such a scenario will be using a different sorting algorithm: [External Sort|https://en.wikipedia.org/wiki/External_sorting]. The goal of the current ticket is to implement a new operator (EnumerableExternalSort) to provide this feature. was: Sometimes we new to sort a big volume of data which does not fit into memory.
