Hi everyone,
Thank you to everyone that have responded to my email. I really
appreciate that. I am sorry for not making it clear in my original
post that what I am looking for is the list of keys in the database
assuming that the client application does not know the keys. From what
I understand, RangeSliceQuery requires you to pass the startKey, which
means the client application have to know beforehand the key that will
be used as startkey.
So, I am trying to do this in cassandra:
select id from table_name;
while RangeSliceQuery would be something like this in SQL (CMIIW),
which is not what I want:
select id from table_name where id between 100 and 1000;
Please let me know whether what I am after is achievable in cassandra.
Kind regards,
Joshua.
