InfluxDB 3 Core always writes and stores data using the Parquet
storage engine—see [Data durability](/influxdb3/core/reference/internals/durability/)for how data flows from write to Parquet persistence.
InfluxDB 3 Enterprise also offers an upgraded storage engine as an
alternative; InfluxDB 3 Core does not include it.
