      Description

      In the following scenario, the master's merge process will gradually slow down or even appear OOM.

      • merge a storage group with very many time series, both timeseries's ```MeasurementSchema``` is different.

      As an example, I generate a device called d1 within the storage group ```root.sg```. The device has 300,000 sensors(s0-s299,999). Then the problem occured.
