feat(#435): exact ReadProjectionProgressAsync(ShardName) overload#529
Merged
Conversation
…IEventDatabase Adds a second, exact per-cell progression read alongside the (projectionName, tenantId) overload: the caller supplies the full ShardName it already holds (e.g. a cell from AllProjectionProgress), so the store looks up the single row whose stored identity equals name.Identity with no version/shard collapsing. A blue/green deploy's versions, a sliced projection's shard keys, and per-tenant partitions each address their own row unambiguously; a ShardKey of "All" is the projection's global cell, matching the store's "All means the whole projection" convention. Ships as a default interface member that throws NotSupportedException (same contract as the existing overload): null is the meaningful "no row yet" answer and must not be borrowed by a store that has not implemented this. Event stores (Marten, Polecat) override it against their progression table in follow-ups. Bumps to 2.29.0.
