Struct TuneRecord 

pub struct TuneRecord<K> {
    pub table: String,
    pub entry: PersistentCacheKey<K>,
    pub winner: usize,
    pub trials: Vec<Trial>,
    pub short_circuit: Option<String>,
    pub wall: Duration,
    pub dry_run: bool,
    pub stored: bool,
}

How one autotune key was decided.

Fields

table: String

The namespace of the table the answer is stored in.

entry: PersistentCacheKey<K>

The table’s entry the answer is stored under: the key, and the checksum of the candidate list it was tuned under.

winner: usize

The index of the candidate the key runs.

trials: Vec<Trial>

The candidates that ran, in the order they ran.

short_circuit: Option<String>

The candidate that met the time limit and ended the tune before the rest of the plan ran.

wall: Duration

From the cache miss to the answer committed.

dry_run: bool

Whether the tune ran inside a dry run, where launches compile but do not execute.

stored: bool

Whether the table took the answer. One that measured nothing, or that was tuned with the cache disabled, answers this process alone: the table holds another answer to the key, or none.
