Chen Li commented on ASTERIXDB-1556:
------------------------------------
Understood. For (2), how does this spilling complicate the algorithm, since
some data structures are now on the disk? For (3) choice 1) seems to be the
ideal one, but I am open to other choices.
Do you have any idea about how much time is needed to make these changes? We
want to unblock the "fuzzy work" soon.
Let's do a discussion when you are available.
> Prefix-based multi-way Fuzzy-join generates an exception.

> When we enable prefix-based fuzzy-join and apply the multi-way fuzzy-join ( >
> 2), the system generates an out-of-memory exception.
> Since a fuzzy-join is created using 30-40 lines of AQL codes and this AQL is
> translated into massive number of operators (more than 200 operators in the
> plan for a 3-way fuzzy join), it could generate out-of-memory exception.
