[jira] [Created] (IOTDB-943) MManager and MTree Lock cause the cpu usage too high

Yuan Tian created IOTDB-943:
-------------------------------

             Summary: MManager and MTree Lock cause the cpu usage too high
                 Key: IOTDB-943
                 URL: https://issues.apache.org/jira/browse/IOTDB-943
             Project: Apache IoTDB
          Issue Type: Improvement
          Components: Core/Engine
            Reporter: Yuan Tian
             Fix For: 0.11.0


When we've already created timeseries, each time we want to insert data of any timeseries, we first need to acquire the lock in MManager to get the schema of that timeseries.

And as the experiment shows that, this will cause the cpu usage be too high while inserting data.
