Limit of Mysql

[Adarsh Sharma]

Dear all,

I want to know the upper limit of mysql after which Mysql-5.*  fails to 
handle large amount of data ( 100's of GB or 100's of TB's ) . After 
which we have to move to some NoSQL databases ( Hadoop, Hive , Hbase).

Currently we have 100 of GB's  data in Mysql -5.1 RDBMS.
 
Is anyone has some experience of moving from these open -source databses 
( Mysql, Postgresql ) to some mechanism of handling data in file systems.

Please share the views.



Thanks & best regards,

Adarsh Sharma
