The process of adjusting timestamp precision from milliseconds to microseconds or nanoseconds if there's an error in Apache IoTDB's timestamp_precision settings can be done by modifying the storage group's TTL (Time to Live) and DPI (Data Point Interval) parameters. Here are the steps for doing this:
SHOW CONCAT(TIME, '', TIMESTAMPPRECISION)
SET STORAGE GROUP <storage_group_name> TTL <ttl_value> DPI 1000
SHOW STORAGE GROUP <storage_group_name>
SET STORAGE GROUP <storage_group_name> TTL 1000000 DPI <dpi_value>
SHOW STORAGE GROUP <storage_group_name>
SHOW CONCAT(TIME, '', TIMESTAMPPRECISION)
By following these steps, the timestamp precision in IoTDB can be adjusted from milliseconds to microseconds or nanoseconds as desired.
