 | Field | Description | Default |
 |-------|-------------|---------|
-| type | Either `auto`, `string`, `long`, `float`, `double`, or `json`. For the `auto` type, Druid determines the most appropriate type for the dimension and assigns one of the following: STRING, ARRAY<STRING>, LONG, ARRAY<LONG>, DOUBLE, ARRAY<DOUBLE>, or COMPLEX<json> columns, all sharing a common 'nested' format. When Druid infers the schema with schema auto-discovery, the type is `auto`. | `string` |

 | name | The name of the dimension. This will be used as the field name to read from input records, as well as the column name stored in generated segments.<br /><br />Note that you can use a [`transformSpec`](#transformspec) if you want to rename columns during ingestion time. | none (required) |
 | createBitmapIndex | For `string` typed dimensions, whether or not bitmap indexes should be created for the column in generated segments. Creating a bitmap index requires more storage, but speeds up certain kinds of filtering (especially equality and prefix filtering). Only supported for `string` typed dimensions. | `true` |
 | multiValueHandling | For `string` typed dimensions, specifies the type of handling for [multi-value fields](../querying/multi-value-dimensions.md). Possible values are `array` (ingest string arrays as-is), `sorted_array` (sort string arrays during ingestion), and `sorted_set` (sort and de-duplicate string arrays during ingestion). This parameter is ignored for types other than `string`. | `sorted_array` |
