Struct WriteAllCacheAliasReport 

Source 
pub struct WriteAllCacheAliasReport { /* private fields */ }
Expand description

Selected registered derived alias cache metadata.

output_indexes uses caller-provided write_all request indexes. It includes outputs that use the selected alias directly or transitively. In an explicit cache chain, an upstream alias can serve an output through a later cached alias instead of through that output’s retained SQL directly.

Implementations§

Source§

impl WriteAllCacheAliasReport

Source

pub fn to_json_value(&self) -> Value

Returns one selected write-all cache alias as a JSON-compatible Python shape.

Source§

impl WriteAllCacheAliasReport

Source

pub const fn table_id(&self) -> u64

Returns the selected registered derived table id.

Source

pub fn alias(&self) -> &str

Returns the selected registered derived alias.

Source

pub fn output_indexes(&self) -> &[usize]

Returns selected output indexes that use this alias.

Source

pub const fn status(&self) -> WriteAllCacheAliasStatus

Returns this alias cache lifecycle status for the write_all call.

Source

pub fn phase_timings(&self) -> &[PhaseTimingReport]

Returns lifecycle timings for an attempted cache alias.

Plan-shaped WriteAllCacheAliasStatus::Selected reports return an empty slice because no lifecycle phase was attempted.

Source

pub fn failed_phase(&self) -> Option<&str>

Returns the primary failed lifecycle phase for a failed alias.

Source

pub const fn execution_profile(&self) -> Option<&QueryExecutionProfile>

Returns the terminal profile for this alias’s cache materialization.

Disabled profiling and failures before physical-plan creation return None. Selected plan metadata is not executed and also returns None. Output query profiles remain separate from this cache profile.
