                                                                                                                  com.google.cloud.bigtable.data.v2.models.ChangeStreamContinuationToken token)
                                                                                                           throws java.lang.IllegalArgumentException
        Return the continuation token with correct partition. The partition in the ChangeStreamContinuationToken for merges is not the correct partition (this is a backend bug that is being fixed). The partition currently represents the child partition, where the current partition should merge to.

        For example: Partition [A, B) gets CloseStream to merge into [A, C). The ChangeStreamContinuationToken returned is { partition = [A, C), token = "token1" } . However, the correct ChangeStreamContinuationToken should be { partition = [A, B), token = "token1" }.

        Parameters:
        parentPartition - parent partition where the ChangeStreamContinuationToken is generated
        token - ChangeStreamContinuationToken to be fixed
        Returns:
        ChangeStreamContinuationToken with correct partition field
        Throws:
        java.lang.IllegalArgumentException
