FEAT: Add runner for local distributed execution (#11609)
Browse files Browse the repository at this point in the history
Summary:
Adds LocalRunner and LocalSchema for running distributed Velox plans in-process with multiple fragments and multiple tasks per fragment. This introduces the abstractions for distributed plans, their options, schema and split sources.

Adds an extension of PlanBuilder for building plan trees with shuffles. These get partitioned into multiple plan trees for execution with LocalRunner.

Adds LocalRunnerTestBase, a test base class with utilities for generating multiple tables each with multiple files of test data. These are then returned as a LocalSchema that can be used to produce splits for LocalRunner.

Adds error propagation for TaskCursor since distributed plans may have to produce errors from any fragment that are consumed by the application via TaskCursor.

This will be generalized to distributed execution on a cluster with Velox coordination and shuffles.
