Trait Implementations§

impl Connection for Connection<'_>

Source§

fn committer_watermark<'life0, 'async_trait>( &'life0 mut self, pipeline: &'static str, ) -> Pin<Box<dyn Future<Output = Result<Option<CommitterWatermark>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Connection<'_>: 'async_trait,

Given a pipeline, return the committer watermark from the Store. This is used by the indexer on startup to determine which checkpoint to resume processing from.
Source§

fn reader_watermark<'life0, 'async_trait>( &'life0 mut self, pipeline: &'static str, ) -> Pin<Box<dyn Future<Output = Result<Option<ReaderWatermark>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Connection<'_>: 'async_trait,

Given a pipeline, return the reader watermark from the database. This is used by the indexer to determine the new reader_lo or inclusive lower bound of available data.
Source§

fn pruner_watermark<'life0, 'async_trait>( &'life0 mut self, pipeline: &'static str, delay: Duration, ) -> Pin<Box<dyn Future<Output = Result<Option<PrunerWatermark>, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Connection<'_>: 'async_trait,

Get the bounds for the region that the pruner is allowed to prune, and the time in milliseconds the pruner must wait before it can begin pruning data for the given pipeline. The pruner is allowed to prune the region between the returned pruner_hi (inclusive) and reader_lo (exclusive) after waiting until pruner_timestamp + delay has passed. This minimizes the possibility for the pruner to delete data still expected by inflight read requests.
Source§

fn set_committer_watermark<'life0, 'async_trait>( &'life0 mut self, pipeline: &'static str, watermark: CommitterWatermark, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Connection<'_>: 'async_trait,

Upsert the high watermark as long as it raises the watermark stored in the database. Returns a boolean indicating whether the watermark was actually updated or not.
Source§

fn set_reader_watermark<'life0, 'async_trait>( &'life0 mut self, pipeline: &'static str, reader_lo: u64, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Connection<'_>: 'async_trait,

Update the reader_lo of an existing watermark entry only if it raises reader_lo. Readers will reference this as the inclusive lower bound of available data for the corresponding pipeline. Read more
Source§

fn set_pruner_watermark<'life0, 'async_trait>( &'life0 mut self, pipeline: &'static str, pruner_hi: u64, ) -> Pin<Box<dyn Future<Output = Result<bool, Error>> + Send + 'async_trait>>
where 'life0: 'async_trait, Connection<'_>: 'async_trait,
