Your question is missing a "what". What do you want to know the default of?
If you are asking for the key_validation_class of the Index CF, then it's the column type that defines it. If you're asking about the index CF comparator, then in that example it would use a comparator that sorts like your partitioner (so if you say use the RandomPartitioner, the comparator will sort by md5). And no, none of those can be changed (it would make no sense for the key_validation_class, as for the comparator, the 2ndary index implementation relies pretty much by design on the ordering being the one of the partitioner). -- Sylvain On Mon, Jan 28, 2013 at 11:57 AM, Alan Ristić <alan.ris...@gmail.com> wrote: > I'm just curious for C* v1.2.. > > a) Does automatic secondary INDEX CF defaults to primary CF > key_validation_class<http://www.datastax.com/docs/1.2/configuration/storage_configuration#key-validation-class> > ('user_id' in example) or it decides by column type (varchar in 'email' > case) what key_validation_class should be ? > *I suppose it defaults.* > > example: > CREATE TABLE users ( > user_id uuid PRIMARY KEY, > created_at timestamp, > email varchar, > ... > ) WITH > comment='Registered user'; > > CREATE INDEX ON users (email); > > *b) And if yes can it be changed on CREATE INDEX? * > *I suppose no.* > > ps: I know that sec. index in example is not optimal ;) > > Tnx, > *Alan Ristić* > > *t*: @alanristic <http://twitter.com/alanristic> > *m*: 040 423 688 >
