Enum ReplicaFallback 

Source 
#[non_exhaustive]
pub enum ReplicaFallback {
    FailReadiness,
    Primary,
}
Expand description

Behavior when a configured read replica is unavailable or stale.

Variants (Non-exhaustive)§

This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
§

FailReadiness

Readiness should fail when the configured replica cannot safely serve reads.

§

Primary

Read paths may use the primary when the replica is unavailable or stale.
