             Summary: Refactor virtual storage group funtion
                 Key: IOTDB-2051
                 URL: https://issues.apache.org/jira/browse/IOTDB-2051
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: Jialin Qiao


We introduce the virtual storage group (N), for each logical storage group, there are N virtual sgs (StorageGroupProcessor).

 

However, the number of all virtual sgs are still related to the moduling of user.

 

It's better to let users define how many insertion threads or locks are in a storage engine.

Then, we allocate these threads dynamically to each logical storage group.

Virtual storage groups only impact the memtable in memory, their TsFiles are still stored in the same folder.
