[jira] [Created] (IOTDB-1059) Use current system timestamp when
insert data points without timestamps
Haonan Hou created IOTDB-1059:
---------------------------------
Summary: Use current system timestamp when insert data points without timestamps
Key: IOTDB-1059
URL: https://issues.apache.org/jira/browse/IOTDB-1059
Project: Apache IoTDB
Issue Type: New Feature
Components: Core/Engine
Reporter: Haonan Hou
When the users insert data without timestamp, the server should use the current system timestamp to pair with the data points.
For example, to support sql statement like this:
{code:sql}
insert into root.ln.wf02.wt02(status, hardware) VALUES (false, 'v2'){code}
Then the query result will be:
{code:java}
+-----------------------------+--------------------------+------------------------+
| Time|root.ln.wf02.wt02.hardware|root.ln.wf02.wt02.status|
+-----------------------------+--------------------------+------------------------+
|2020-12-15T08:00:00.002+08:00| v2| false|
+-----------------------------+--------------------------+------------------------+
Total line number = 2
It costs 0.170s
{code}
The session client can support this feature as well.
