---------------------------------

             Summary: First construct a batch then run the batch for continuous queries
                 Key: SPARK-14942
                 URL: https://issues.apache.org/jira/browse/SPARK-14942
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.0.0
            Reporter: Liwei Lin


Currently in {{StreamExecution}}, we first run the batch, then construct the next:
{code}
if (dataAvailable) runBatch()
constructNextBatch()
{code}

This is good if we run batches ASAP, where data would get processed in the very next batch:

However, if we run batches at trigger like {{ProcessTime("1 minute")}}, data - such as y below - may not get processed in the very next batch i.e. batch 1, but in batch 2:
