This is not as simple as querying Mysql ...
Records that are similar are determined by many factors.
So I need to pass the information to validate or not the fact that several lines should be considered similar.
I do not want to overload the server with thousands of queries, or create tables with the memory storage engine.
When I thought, in fact, what I need is to be able to recover the data I have to deal with the MySQL server, keep them in memory on the server that executed the script, and access such a simple way as Mysql. A kind of NoSQL inside perl actually, to manipulate my data on the fly, create temporary tables etc. ..
The only thing I found is that looks like this:
http://search.cpan.org/ ~ vladb/DBIx-DataLookup-0.03/DataLookup/DataLookup.pm but this no longer seems maintained
Any suggestions?
