A sync destination: a warehouse, a column store, files in object storage.
Not a database adapter. No model is stored in a destination and no query is served from one; a capture stream is written to it.
- Implementers
Properties
- deduplicates → bool
-
Whether applying a change twice leaves the same result. None promises
exactly-once delivery; this is what makes at-least-once harmless.
no setter
- hashCode → int
-
The hash code for this object.
no setterinherited
- name → String
-
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
backfillComplete(
String model, int throughSequence, {String? tenant}) → Future< void> -
A backfill copied every live row of
modelas ofthroughSequence; anything the destination holds that the backfill did not touch and no later change wrote is gone from the source. -
erase(
List< DVCapturedChange> changes) → Future<void> - Applies an erasure now, out of band, superseding every change to the same records with a lower sequence -- including one already in flight.
-
evolve(
DVCaptureSchemaChange change) → Future< void> - Adds or removes columns. Must be idempotent: a crash after it and before the checkpoint delivers it again.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
toString(
) → String -
A string representation of this object.

-
write(
DVCaptureBatch batch) → Future< void> -
Applies
batch. Throwing leaves the checkpoint where it was, and the whole batch is delivered again (DV-CDC-001).
Operators
-
operator ==(
Object other) → bool -
The equality operator.
