Haimei Guo commented on IOTDB-882:
----------------------------------
As one thread pool manages all insert requests from the client, the insert
requests may not come from a single thread. If we cache metadata in a client
thread, we may not maintain the same map for all insert requests. We need to
maintain a global metadata map.
> Cache metadata in each session to avoid checking in each insert

> Normally a client write the same device or timeseries, we could cache
