Enum SHJStreamState 

pub enum SHJStreamState {
    PullRight,
    PullLeft,
    RightExhausted,
    LeftExhausted,
    BothExhausted {
        final_result: bool,
    },
}

Represents the various states of an symmetric hash join stream operation.

This enum is used to track the current state of streaming during a join operation. It provides indicators as to which side of the join needs to be pulled next or if one (or both) sides have been exhausted. This allows for efficient management of resources and optimal performance during the join process.

Variants

PullRight

Indicates that the next step should pull from the right side of the join.

PullLeft

Indicates that the next step should pull from the left side of the join.

RightExhausted

State representing that the right side of the join has been fully processed.

LeftExhausted

State representing that the left side of the join has been fully processed.

BothExhausted

Represents a state where both sides of the join are exhausted.

The final_result field indicates whether the join operation has produced a final result or not.

Fields

final_result: bool
