---------------------------------

             Summary: Specify configuration when start iotdb
                 Key: IOTDB-574
                 URL: https://issues.apache.org/jira/browse/IOTDB-574
             Project: Apache IoTDB
          Issue Type: New Feature
            Reporter: Houliang Qi


now when start iotdb, default configuratiuon is used. If user can specify some configurations, it will be more user-friendly, there have two options:
 # Users can specify another configuration file, iotdb use the new configure file to start; eg： _./start-server.sh -c path/new_iotdb-engine.properties_
 # Users can specify some configuration items to override the default configuration; eg:  ./start-server.sh -timestamp_precision=ns -rpc_port=6668 -enable_wal=false

 

TDEngine only support the first option([https://github.com/taosdata/TDengine]); Influxdb support the second option, but only a few specific options are supported([https://github.com/influxdata/influxdb])；

In my opinion, I prefer the first option for the following reasons:

1. Users can specify different configuration files according to different use scenarios;

2. The description of configuration items can be better described in the configuration file;
