Timeline Index |
|
Timeline index is a special form of range index which is defined using date-time constants or expressions. A timeline should only be created over a numeric field used to hold date, time, or date-time data. The endpoints are defined by date-time values such as `Jan 1, 2000`, and the size of each slot is a date-time constant such as `1 day`. Items that fall outside the timeline may be included within the slot corresponding to the nearest endpoint, included in a special overflow slot, or discarded from the index.
Timeline indexes are defined by the following properties:
