I'm using Cassandra 1.1.2 I'm trying to convert a RDBMS application to Cassandra. In my RDBMS application I have following table called table1:
| Col1 | Col2 | Col3 | Col4 |
- Col1: String (primary key)
- Col2: String (primary key)
- Col3: Bigint (index)
- Col4: Bigint
This table counts over 200 million records. Mostly used query is something like:
Select * from table where col3 < 100 and col3 > 50;
In Cassandra I used following statement to create the table:
create table table1 (primary_key varchar, col1 varchar,
col2 varchar, col3 bigint, col4 bigint, primary key (primary_key));
create index on table1(col3);
I changed the primary key to an extra column (I calculate the key inside my application). After importing a few records I tried to execute following cql:
select * from table1 where col3 < 100 and col3 > 50;
This result is:
Bad Request: No indexed columns present in by-columns clause with Equal operator
The Query select col1,col2,col3,col4 from table1 where col3 = 67 works
Google said there is no way to execute that kind of queries. Is that right? Any advice how to create such a query?
