Required Methods§

Source

fn pre_write<'life0, 'life1, 'async_trait>( &'life0 self, request: &'life1 RowInsertRequests, ctx: QueryContextRef, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Runs pre-write checks/hooks for prometheus remote write requests.

Source

fn write_prepared<'life0, 'async_trait>( &'life0 self, request: RowInsertRequests, ctx: QueryContextRef, with_metric_engine: bool, ) -> Pin<Box<dyn Future<Output = Result<Output>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Writes one batch after Self::pre_write has succeeded for the entire request.

Source

fn write<'life0, 'async_trait>( &'life0 self, request: RowInsertRequests, ctx: QueryContextRef, with_metric_engine: bool, ) -> Pin<Box<dyn Future<Output = Result<Output>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

where Self: 'async_trait, 'life0: 'async_trait,

Checks every batch before writing any of them.

Source

fn read<'life0, 'async_trait>( &'life0 self, request: ReadRequest, ctx: QueryContextRef, ) -> Pin<Box<dyn Future<Output = Result<PromStoreResponse>> + Send + 'async_trait>>
