----------------------------------------
Hi,
I'm investigating use of Spark for matching patterns in symbolically
represented time series where the sliding functionality as available from scala
iterators would make life a lot easier.
>From the ticket I'd say this functionality is implemented (status resolved,
>fix version 1.0.0, ...), but I can't find it in the docs and the PR indicates
>that this functionality hasn't made it into Spark (just yet ...). Is this
>functionality available?
Cheers,
Frens
Background: I want to compare strings of segments to other (larger) strings of
segments. As segment strings may be split up over partitions, the more straight
forward aproaches I could come up with don't work.
