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

             Summary: write wal slowly
                 Key: IOTDB-1533
                 URL: https://issues.apache.org/jira/browse/IOTDB-1533
             Project: Apache IoTDB
          Issue Type: Bug
          Components: WAL
    Affects Versions: 0.12.1
            Reporter: Jialin Qiao
         Attachments: config.properties, image-2021-07-28-11-06-07-093.png

In rel/0.12, commit id: 2489b6e871a695d0db8cc5dd2a781b600c48969a

 

We use 100 clients, 100 storage groups in IoTDB-benchmark. This will occur in about 2 minutes.

 

config.properties is the config of iotdb-benchmark.

 

We could see the following message：

!image-2021-07-28-11-06-07-093.png|width=1451,height=209!

 

This may be due to the schedule of the flushBuffer thread.
