"""
Finds the complete set of frequent sequential patterns in the
input sequences of itemsets.
- :param data: The input data set, each element contains a sequnce
of itemsets.
- :param minSupport: the minimal support level of the sequential
pattern, any pattern appears
- more than (minSupport * size-of-the-dataset) times will be
output (default: `0.1`)
- :param maxPatternLength: the maximal length of the sequential
pattern, any pattern appears
- less than maxPatternLength will be output. (default: `10`)
- :param maxLocalProjDBSize: The maximum number of items (including
delimiters used in
- the internal storage format) allowed in a projected database
before local
- processing. If a projected database exceeds this size, another
- iteration of distributed prefix growth is run. (default:
`32000000`)
