------------------------------------
Summary: Using a long ID to represent device and sensor (and Path)
Key: IOTDB-85
URL: https://issues.apache.org/jira/browse/IOTDB-85
Project: Apache IoTDB
Issue Type: Improvement
Reporter: xiangdong Huang
Now in IoTDB, all devices and sensors and their Paths are organized by String,
as a result, we have many `Map<String, Object>` structures.
If we can convert the path to a long ID, it is helpful for saving memory and
accelerate operations on Map.
However, because we support SQLs like `select * from root.*.a.b.*`, simply
maping a string to a long is not enough, we have to consider the encoding
method from a string to a long carefully to support the above SQLs.
Does anyone have good idea?
