Taewoo Kim commented on ASTERIXDB-1556:
---------------------------------------

Here, what does N (1 ... N) mean? The number of unique hash values? or the 
number of frames? 

> 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.
