Expand description

Progress of all actors containing backfill executors while creating mview.

Fields§

§states: HashMap<ActorId, BackfillState>§backfill_order_state: BackfillOrderState§done_count: usize§backfill_upstream_types: HashMap<ActorId, BackfillUpstreamType>

Tells whether the backfill is from source or mv.

§upstream_mv_count: HashMap<TableId, usize>

Upstream mv count. Keep track of how many times each upstream MV appears in this stream job.

§upstream_mvs_total_key_count: u64

Total key count of all the upstream materialized views

§mv_backfill_consumed_rows: u64§source_backfill_consumed_rows: u64§mv_backfill_buffered_rows: u64

Buffered rows (for locality backfill) that are yet to be consumed This is used to calculate precise progress: consumed / (upstream_total + buffered)

§definition: String

DDL definition

§create_type: CreateType

Implementations§

Source§

impl Progress

Source

fn new( actors: impl IntoIterator<Item = (ActorId, BackfillUpstreamType)>, upstream_mv_count: HashMap<TableId, usize>, upstream_total_key_count: u64, definition: String, create_type: CreateType, backfill_order_state: BackfillOrderState, ) -> Self

Create a Progress for some creating mview, with all actors containing the backfill executors.

Source

fn update( &mut self, actor: ActorId, new_state: BackfillState, upstream_total_key_count: u64, ) -> PendingBackfillFragments

Update the progress of actor. Returns the backfill fragments that need to be scheduled or cleaned up.

Source

fn is_done(&self) -> bool

Returns whether all backfill executors are done.

Source

fn actors(&self) -> impl Iterator<Item = ActorId> + '_

Returns the ids of all actors containing the backfill executors for the mview tracked by this Progress.

Source

fn calculate_progress(&self) -> String

progress = consumed_rows / upstream_total_key_count
