Jialin Qiao commented on IOTDB-882:
-----------------------------------
Hi, the idea is to cache the metadata on the server-side. For each client, the
server will create a client-thread to serve this session. Cache the metadata in
the client-thread may avoid access MManager in PlanExecutor.

> In each insertion, we will check the MManager to see if the data type is

> Normally a client write the same device or timeseries, we could cache
> metadata in the client-thread in server to accelerate the insertion.
