Enum TableParallelism 

Source 
pub enum TableParallelism {
    Adaptive,
    Fixed(usize),
    Custom,
}
Expand description

The parallelism for a TableFragments.

Variants§

§

Adaptive

This is when the system decides the parallelism, based on the available worker parallelisms.

§

Fixed(usize)

We set this when the TableFragments parallelism is changed. All fragments which are part of the TableFragment will have the same parallelism as this.

§

Custom

We set this when the individual parallelisms of the Fragments can differ within a TableFragments. This is set for risectl, since it has a low-level interface, scale individual Fragments within TableFragments. When that happens, the TableFragments no longer has a consistent parallelism, so we set this to indicate that.
