Thanks for = all your guys’ information.

This thread = make us raised a concern: we choose Cassandra because FB,Twitter,Digg are using = them, and we’re doubting whether Cassandra is definitely = trustable.

The question = is what action will we take, if after a few time, these big tech company really start = to leave Cassandra.

 

Will we have = the confidence to trust Apache Cassandra, instead of following these tech = company’s storage solution. J

 

Thanks and = Regards.
