Hi Julian,
Here is our discussion:
## Goals
1. let's support double quota on multiply locations of a path (not only the
measurement);
2. let's uniform the convert between path and string;
3. maybe we can expose Path object to users in session API.
## Examples
### Session
```
String deviceId = "root.sg1.\"d..1\"";
List<String> measurements = new ArrayList<>();
measurements.add("\"s..1\"");
```
### JDBC
```
statement.execute("insert into root.sg1.\"d..1\"(timestamp,
\"s..1\") values(1,2)");
statement.execute("select * from root");
headers in result:
+-----------------------------+-------------------------------+
| Time|root.turbine1.\"d..1\".\"s..1\"|
+-----------------------------+-------------------------------+
|1970-01-01T08:00:00.001+08:00| 2.0|
+-----------------------------+-------------------------------+
```
### TsFile
We store the following Strings in file:
```
String devceId = "root.sg1.\"d..\1";
String measurementId = "\"s..1\"";
```
### Schema tree in IoTDB
root -> sg1 -> \"d..1\" -> \"s..1\"
Thanks,
