[jira] [Created] (IOTDB-86) More data types support

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

             Summary: More data types support
                 Key: IOTDB-86
                 URL: https://issues.apache.org/jira/browse/IOTDB-86
             Project: Apache IoTDB
          Issue Type: Improvement
            Reporter: xiangdong Huang


Hi, 

Currently IoTDB supports BOOLEAN (Boolean), INT32 (Integer), INT64 (Long Integer), FLOAT (Single Precision Floating Point), DOUBLE (Double Precision Floating Point), TEXT (String).

As in many applications, the sensor does not  only  generate a numeric value, but also an array. 

For example, GPS is a special array which consists of longitude, latitude and altitude. 

For  another example, a camera generates photos and will save the feature data (e.g., a SIFT feature) of each photo into IoTDB.

Except for that, enum is very very common in industrial applications.

 

So, I think it is great if we can support enum (in an efficient way) and array data type.
