  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.

  11. def getSnapshot(sourceConfiguration: DeltaConnectorConfiguration): Snapshot

    This method returns a Snapshot instance acquired from #deltaLog.

    This method returns a Snapshot instance acquired from #deltaLog. This implementation tries to query the Snapshot in below order, stopping at first non-empty result:

    • If DeltaSourceOptions#STARTING_VERSION was specified, use it to call DeltaLog#getSnapshotForVersionAsOf(long).
    • If DeltaSourceOptions#STARTING_TIMESTAMP was specified, use it to call DeltaLog#getSnapshotForTimestampAsOf(long).
    • Get the head version using DeltaLog#snapshot()
    returns

    A Snapshot instance or throws java.util.NoSuchElementException if no snapshot was found.
