  • Single Tag Value Delete

    This API deletes the data contained in a specific Tag . tag_name is the name of the tag to be deleted, base_time is the time value of the data to be deleted, and all data before this time are deleted. If base_time is not entered, all data of the corresponding tag is deleted. The default format is "YYYY-MM-DD HH24:MI:SS", determined in seconds.

  • All Tag Value Delete

    This API deletes all data from data lake before the specific time specified as base_time for all tags at once. This function is generally called when data in a specific range is no longer needed after data backup is complete, and is used to free up storage space. Date format is the same as Single Tag Delete. If base_time is not specified, all data for all tags would be deleted.

  • Calculated Tag Value Delete

    This API deletes the calculated data automatically created by Machlake. Since this calculated data is designed not to be deleted even if the original tag data is deleted, a separate deletion process is required. All data before the time specified as base_time can be deleted. If this value is not specified, all data existing in calculated will be deleted.
