Enum TableRole 

pub enum TableRole {
    Written,
    Landing,
    Identity,
}

What a table is to the load that touches it.

A storage renderer is asked the same questions about different tables, and some answers depend on which kind it is: emptying one day of a table the load is about to write keeps somewhere for that day, while emptying one day of the landing table the load has just read can drop it.

Variants

Written

A table a load writes: the target, or a table that holds its rows.

Landing

The landing table a load reads one day of, staged there before the load ran. Once the load has read the day, nothing reads it again.

Identity

The identity table beside a written table, holding one row per key.
