I think we can change the function `distribution_from_join_type`
```
JoinType::Inner | JoinType::Left | JoinType::LeftSemi |
JoinType::LeftAnti => {
// need the left data, and the right should be one partition
vec![
Distribution::UnspecifiedDistribution,
Distribution::SinglePartition,
]
}
```
to
```
JoinType::Inner | JoinType::Left | JoinType::LeftSemi | JoinType::LeftAnti
=> {
// need the left data, and the right should be one partition
vec![
Distribution::SinglePartition,
Distribution::SinglePartition,
]
}
```
temporarily If we can not support executing multi times for one physical
executor for the same partition.
It will not block your fix for the issue
