String data type

Defines a data type for variable-length UTF8 strings.

Permitted fill values

The value of the fill_value metadata key must be unicode string.

For example, the array metadata below specifies that the array contains variable-length byte strings:

json

{
    "data_type": "string",
    "fill_value": "foo",
    "codecs": [{
        "name": "vlen-utf8"
    }],
}

Currently, this data type is only compatible with the "vlen-utf8" codec.
