… be the same (#427) This is one PR from the following stack of PRs: - #427 <- you are here - #469 - #461 - #462 - #463 - #464 - #432 This is a preparatory step towards: - #377 This is an optimization that allows workers to communicate in-memory avoiding network calls and serialization in case it needs to communicate to itself. This optimization shows good improvements if using a small number of workers, and fades away as more workers are used. Even if this shows improvements today, it will become very meaningful in adaptative query execution: there will be times when two consecutive stages are assigned 1 task each, and as that was done dynamically, we cannot eagerly do the optimization that collapses those two stages into one, so instead, we assigned both stages to the same worker, and the optimization in this PR kicks in, executing the plan fully locally.

This PR introduces a MaxGauge metric to provide better tracking of peak values in distributed metrics collection. This enables more accurate monitoring of resource utilization and helps identify bottlenecks in the execution pipeline.
