    • incrementalSnapshotContext

      private final IncrementalSnapshotContext<TableId> incrementalSnapshotContext

    • snapshotScn

      private final Scn snapshotScn
      SCN that was used for the initial consistent snapshot. We keep track of this field because it's a cutoff for emitting DDL statements, in case we start mining _before_ the snapshot SCN to cover transactions that were ongoing at the time the snapshot was taken.

    • snapshotPendingTransactions

      private Map<String,Scn> snapshotPendingTransactions
      Map of (txid, start SCN) for all transactions in progress at the time the snapshot was taken.

    • snapshotCompleted

      private boolean snapshotCompleted
      Whether a snapshot has been completed or not.
