Enum LoadStep

pub enum LoadStep {

}
Expand description

A step of loading a store from storage (§13.4), in the order they run. A step runs only when it has work to do.

Variants§

§

FindingKeys

Reading slots for copies of this member’s keys: from the floor’s first kept slot, or from slot 1 without a floor, or, for a join, from its invite, to the end of the sequence. It runs only when the floor holds no copy for this member. Done counts the slots passed and total the end found once the first slot is read; slots that land while it reads raise the total.

§

Streaming(Audience)

Streaming one of the floor’s snapshots from storage, staging its rows as they arrive: the store’s first, then each circle’s this member reads. Done and total count bytes of the snapshot’s object.

§

Installing

Installing the staged snapshots’ rows. Done and total count tables: installing passes over each snapshot’s tables six times, to copy their rows, check them three ways, write their merge records and check that every row has one, and each table counts once in each pass.

§

InstallingSlots

Applying the slots from the snapshots’ coverage to the load’s target, in the same transaction. Done and total count slots.

§

Reading

Reading the slots after that target, to the end of the sequence. Done and total count slots; the total is the end found as the step begins, and grows if slots land while it reads.

§

Applying

Applying the slots it read, one transaction each. Done and total count slots.
