[jira] [Created] (IOTDB-1440) Auto adjust the primitive_array_size

Jialin Qiao created IOTDB-1440:
----------------------------------

             Summary: Auto adjust the primitive_array_size
                 Key: IOTDB-1440
                 URL: https://issues.apache.org/jira/browse/IOTDB-1440
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Jialin Qiao


We calculate the new primitive_array_size as long as the total time series changed. 

If the new primitive_array_size reaches the change threshold, we start the adjust:

 

Store the size in TVList.

 

When an empty TVList applies a new array, give it the new size array.

When a non-empty TVList applies a new array, give it the origin size array. 

 

If the put-backed array size is different from the new size, just discard it.
