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.
