------------------------------------
Summary: Support more precise time unit (microsecond or nanosecond)
Key: IOTDB-88
URL: https://issues.apache.org/jira/browse/IOTDB-88
Project: Apache IoTDB
Issue Type: Task
Reporter: xiangdong Huang
When Haier Group (a very famous manufacturer in China) uses IoTDB, they find
the precision of the timestamp is not sufficient. In their production line,
the precision of timestamp is 0.1 microsecond.
Now, IoTDB uses long to store timestamp, which is fine for millisecond,
microsecond and nanosecond, but IoTDB just parse a long timestamp as
millisecond. So, we can provide a parameter in configuration files to set the
time unit of the long value.
3 choices need to be supported: millisecond, microsecond, and nanosecond.
