Struct mz_compute_client::service::TrackedFrontiers
source · struct TrackedFrontiers<T> {
write_frontier: (MutableAntichain<T>, Vec<Antichain<T>>),
input_frontier: (MutableAntichain<T>, Vec<Antichain<T>>),
output_frontier: (MutableAntichain<T>, Vec<Antichain<T>>),
}
Expand description
Tracked frontiers for an index or a sink collection.
Each frontier is maintained both as a MutableAntichain
across all partitions and individually
for each partition.
Fields§
§write_frontier: (MutableAntichain<T>, Vec<Antichain<T>>)
The tracked write frontier.
input_frontier: (MutableAntichain<T>, Vec<Antichain<T>>)
The tracked input frontier.
output_frontier: (MutableAntichain<T>, Vec<Antichain<T>>)
The tracked output frontier.
Implementations§
source§impl<T> TrackedFrontiers<T>
impl<T> TrackedFrontiers<T>
sourcefn all_empty(&self) -> bool
fn all_empty(&self) -> bool
Returns whether all tracked frontiers have advanced to the empty frontier.
sourcefn update_write_frontier(
&mut self,
shard_id: usize,
new_shard_frontier: &Antichain<T>,
) -> Option<Antichain<T>>
fn update_write_frontier( &mut self, shard_id: usize, new_shard_frontier: &Antichain<T>, ) -> Option<Antichain<T>>
Updates write frontier tracking with a new shard frontier.
If this causes the global write frontier to advance, the advanced frontier is returned.
sourcefn update_input_frontier(
&mut self,
shard_id: usize,
new_shard_frontier: &Antichain<T>,
) -> Option<Antichain<T>>
fn update_input_frontier( &mut self, shard_id: usize, new_shard_frontier: &Antichain<T>, ) -> Option<Antichain<T>>
Updates input frontier tracking with a new shard frontier.
If this causes the global input frontier to advance, the advanced frontier is returned.
sourcefn update_output_frontier(
&mut self,
shard_id: usize,
new_shard_frontier: &Antichain<T>,
) -> Option<Antichain<T>>
fn update_output_frontier( &mut self, shard_id: usize, new_shard_frontier: &Antichain<T>, ) -> Option<Antichain<T>>
Updates output frontier tracking with a new shard frontier.
If this causes the global output frontier to advance, the advanced frontier is returned.
sourcefn update_frontier(
entry: &mut (MutableAntichain<T>, Vec<Antichain<T>>),
shard_id: usize,
new_shard_frontier: &Antichain<T>,
) -> Option<Antichain<T>>
fn update_frontier( entry: &mut (MutableAntichain<T>, Vec<Antichain<T>>), shard_id: usize, new_shard_frontier: &Antichain<T>, ) -> Option<Antichain<T>>
Updates the provided frontier entry with a new shard frontier.
