-> Nested columns is an experimental feature available starting in Apache Druid
24.0. Like most experimental features, functionality documented on this page is
subject to change in future releases. However, the COMPLEX column type includes
versioning to provide backward compatible support in future releases. We
strongly encourage you you experiment with nested columns in your development
environment to evaluate that they meet your use case. If so, you can use them
in production scenarios. [...]

Apache Druid supports directly storing nested data structures in
`COMPLEX<json>` columns. `COMPLEX<json>` columns store a copy of the structured
data in JSON format and specialized internal columns and indexes for nested
literal values—STRING, LONG, and DOUBLE types. An optimized [virtual
column](./virtual-columns.md#nested-field-virtual-column) allows Druid to read
and filter these values at speeds consistent with standard Druid LONG, DOUBLE,
and STRING columns.
