[jira] [Created] (IOTDB-719) Active flush when points in each series reaches a threshold

Jialin Qiao created IOTDB-719:
---------------------------------

             Summary: Active flush when points in each series reaches a threshold
                 Key: IOTDB-719
                 URL: https://issues.apache.org/jira/browse/IOTDB-719
             Project: Apache IoTDB
          Issue Type: Improvement
          Components: Core/Engine
            Reporter: Jialin Qiao


When disable parameter adapter, and set the memtable size to 1G, if we write 10 series, then each series will retain 6M points in memory.

When query, many points need to be copied and sorted, the query will be very slow.

This may highly impact the user experience. We need to add a flush mechanism.
