Smart Storage#

In order to handle data, Shapelets uses very efficient data structures which rely on a technique named bitmap indexing. This technique offers particularly good results in huge databases, providing faster retrieval of records and greater efficiency in insert, delete and update operations.

When handling time series, temporal indices are discretized and codified as bitmap indices, speeding up operations and providing several advantages, like the ability to store time series sampled at an arbitrarily high frequency.
