- UUIDField
DataStax Enterprise supports the Cassandra TimeUUID type. A value of this type is a Type 1 UUID that includes the time of its generation. Values are sorted, conflict-free timestamps. For example, use this type to identify a column, such as a blog entry, by its timestamp and allow multiple clients to write to the same partition key simultaneously. To find data mapped from a Cassandra TimeUUID to a Solr UUIDField, users need to search for the whole UUID value, not just its time component.
- BCD
A relatively inefficient encoding that offers the benefits of quick decimal calculations and quick conversion to a string.
- SortableDoubleField/DoubleType
If you use the plain types (DoubleField, IntField, and so on) sorting will be lexicographical instead of numeric.
- TrieField
Used with a type attribute and value: integer, long, float, double, date.
Mapping of CQL collections
- Collection list and set: multi-valued field. See Managing the field cache memory and Example: copy fields and docValues
- Collection maps: dynamic field. See Using dynamic fields.
The name of the dynamic field minus the wildcard is the map name. For example, a map column name dyna* is mapped to dyna. Inner keys are mapped to the full field name.
