**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** A clear and concise description of what the problem is. Ex. I'm always frustrated when [...] ``` ❯ create view v as select 1 as a, 2 as b, 3 as c; 0 rows in set. Query took 0.010 seconds. ❯ explain select * from v offset 0 limit 2; +---------------+-------------------------------------------------------+ | plan_type | plan | +---------------+-------------------------------------------------------+ | logical_plan | Limit: skip=0, fetch=2 | | | Projection: #v.a, #v.b, #v.c | | | TableScan: v projection=[a, b, c], fetch=2 | | physical_plan | GlobalLimitExec: skip=0, fetch=2 | | | ProjectionExec: expr=[a@0 as a, b@1 as b, c@2 as c] | | | ProjectionExec: expr=[1 as a, 2 as b, 3 as c] | | | EmptyExec: produce_one_row=true | | | | +---------------+-------------------------------------------------------+ ❯ explain select * from v limit 2; +---------------+-------------------------------------------------------+ | plan_type | plan | +---------------+-------------------------------------------------------+ | logical_plan | Limit: skip=None, fetch=2 | | | Projection: #v.a, #v.b, #v.c | | | TableScan: v projection=[a, b, c], fetch=2 | | physical_plan | GlobalLimitExec: skip=None, fetch=2 | | | ProjectionExec: expr=[a@0 as a, b@1 as b, c@2 as c] | | | ProjectionExec: expr=[1 as a, 2 as b, 3 as c] | | | EmptyExec: produce_one_row=true | | | | +---------------+-------------------------------------------------------+ ``` I'd like `explain select * from v offset 0 limit 2` and `explain select * from v limit 2;` to have same logical plan. Also, in `eliminate_limit.rs`, we should eliminate the `Limit` plan when `fetch = None` and `skip = 0 or skip = None`. **Describe the solution you'd like** A clear and concise description of what you want to happen. **Describe alternatives you've considered** We could not do this. **Additional context** Add any other context or screenshots about the feature request here. -- This is an automated message from the Apache Git Service.
