Soumyava 524842a3bb Window function on msq (#15470) ... This PR aims to introduce Window functions on MSQ by doing the following: Introduce a Window querykit for handling window queries along with its factory and a processor for window queries If a window operator is present with a partition by clause, pushes the partition as a shuffle spec of the previous stage In presence of empty OVER() clause lets all operators loose on a single rac In presence of no empty OVER() clause, breaks down each window into individual stages Associated machinery to handle window functions in MSQ Introduced a separate hidden engine feature WINDOW_LEAF_OPERATOR which is set only for MSQ engine. In presence of this feature, the planner plans without the leaf operators by creating a window query over an inner scan query. In case of native this is set to false and the planner generates the leafOperators Guardrails around materialization Comprehensive UTs		2024-03-28 14:58:34 +05:30
