Compared to previous versions of InfluxDB you can think of a database as a `bucket` in v2 or as a `db/retention_policy` in v1. A `table` is equivalent to a `measurement`, which has columns that can be of type `tag` (a string dictionary), `int64`, `float64`, `uint64`, `bool`, or `string` and finally every table has a `time` column that is a nanosecond precision timestamp. +Compared to previous versions of InfluxDB, you can think of a database as an +InfluxDB v2 `bucket` in v2 or an InfluxDB v1 `db/retention_policy`. +A `table` is equivalent to an InfluxDB v1 and v2 `measurement`. -In InfluxDB 3, every table has a primary key--the ordered set of tags and the time--for its data. -This is the sort order used for all Parquet files that get created.
