##### Front coding
Starting in version 25.0, Druid can store STRING and [COMPLEX<json>](../querying/nested-columns.md) columns using an incremental encoding strategy called front coding. This allows Druid to create smaller UTF-8 encoded segments with very little performance cost.
Front coding is an experimental feature starting in version 25.0. Front coding is an incremental encoding strategy that Druid can use to store STRING and [COMPLEX<json>](../querying/nested-columns.md) columns. It allows Druid to create smaller UTF-8 encoded segments with very little performance cost.
To enable front coding with SQL-based ingestion, define an `indexSpec` in a query context. See [SQL-based ingestion reference](../multi-stage-query/reference.md#context-parameters) for more information.
