Hi all, I found in the explain a "backup stage", but I didn't find any docs explaining what it is.
What is a "backup stage"? Do you have any doc about it? I got this from the `explain formatted' of the TPCH 16 query. "STAGE DEPENDENCIES": { "Stage-9": { "DEPENDENT STAGES": "Stage-3, Stage-6" }, "Stage-8": { "ROOT STAGE": "TRUE", "CONDITIONAL CHILD TASKS": "Stage-10, Stage-3" }, "Stage-2": { "DEPENDENT STAGES": "Stage-0" }, "Stage-0": { "DEPENDENT STAGES": "Stage-5" }, "Stage-6": { "DEPENDENT STAGES": "Stage-10" }, "Stage-10": { "BACKUP STAGE": "Stage-3" }, "Stage-5": { "DEPENDENT STAGES": "Stage-9" }, "Stage-3": {} } Thanks in advance, Edson Ramiro
