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.
