Abstract Value Members

  1. abstract def getSnapshot(sourceConfiguration: DeltaConnectorConfiguration): Snapshot

    returns

    A Snapshot instance acquired from #deltaLog. Every implementation of SnapshotSupplier class can have its own rules about how snapshot should be acquired.

  10. def getHeadSnapshot(): TransitiveOptional[Snapshot]

    A helper method that returns the latest Snapshot at moment when this method was called.

    A helper method that returns the latest Snapshot at moment when this method was called.

    If underlying Delta table, represented by #deltaLog field is changing, for example a new data is being added to the table, every call to this method can return different Snapshot.
