Reading Keys written with salting
Hi to all,
I'd like to know which is the best way to read a key salted with phoenix.
If I read it during a mapreduce job I see a byte in front of the key
(probably the salted prefix) that I don't know how to handle..
Thanks in advance,
Flavio

The advantage is that you don't have to know about salted keys and how
to read them.

There's no other way to read salted keys?
Could you describe me shortly which are the advantages of that inputformat?
it reads the schema of the table and it's able to read the correct data
types of columns?

Hi Flavio,
If you writing a Map Reduce , I would highly recommend using the custom
InputFormat classes written that handle these .
