InfluxDB has specific naming guidelines for its database, measurement, tags, and fields to ensure efficient querying and data storage. The `time` keyword can be used in various contexts but requires special handling when used as a field key or tag key. To select data with a tag that has no value, an empty tag value can be specified using double quotes. When writing data to InfluxDB, the precision of the timestamp matters, and using the coarsest possible timestamp precision is recommended for optimal performance.
