   Hi, I noticed that you are writing a request size of more than 200M, which is actually too large. We suggest reducing the batch size to reduce the memory pressure on the server.
   
   In addition, in version 1.2.0, IoTConsensus was unable to synchronize requests larger than 100M in size, which could cause individual nodes to pile up the wal log after receiving a large request, up to 50GB. This issue was [fixed](https://github.com/apache/iotdb/pull/11145) in version 1.2.2. 
   
   It is recommended to upgrade to 1.2.2, reduce the batch size appropriately and try again
