Re: Composite Slice Query returning non-sliced data

Ah, it's a Hector query question. You may have bette luck on the Hector email list. Or if you can turn on debug logging on the server and grab the query that would be handy. The first thing that stands out is that (in cassandra) comparison operations are not used in a slice range. Cheers

Re: Composite Slice Query returning non-sliced data

I think in this case that's just Hector's way of setting the EOC byte for a component. My guess is that the composite isn't being structured correctly through Hector, as well. On Tue, Jul 10, 2012 at 4:40 AM, aaron morton aa...@thelastpickle.comwrote: The first thing that stands out is that

Re: Composite Slice Query returning non-sliced data

I have tested this extensively and EOC has huge issue in terms of usability of CompositeTypes in Cassandra. As an example: If you have 2 Composite Columns such as A:B:C and A:D:C. And if you do search on A:B as start and end Composite Components, it will return D as well. Because it returns all

Re: Composite Slice Query returning non-sliced data

Aaron, Let me start from the beginning. 1- I have a ColumnFamily called Rollup15 with below definition: create column family Rollup15 with comparator =

Re: Composite Slice Query returning non-sliced data

Something like: This is how I did the write in CLI and this is what it printed. and then This is how I did the read in the CLI and this is what it printed. It's hard to imagine what data is in cassandra based on code. cheers - Aaron Morton Freelance Developer @aaronmorton

Re: Composite Slice Query returning non-sliced data

Can you provide an example of writing and reading column names of a different type. Thanks - Aaron Morton Freelance Developer @aaronmorton http://www.thelastpickle.com On 6/07/2012, at 11:30 AM, Sunit Randhawa wrote: HI Aaron, It is create column family CF

Re: Composite Slice Query returning non-sliced data

Aaron, For writing, i am using cli. Below is the piece of code that is reading column names of different types. Composite start = new Composite(); start.addComponent(0, beginTime, Composite.ComponentEquality.EQUAL);

Re: Composite Slice Query returning non-sliced data

#2 has the Composite Column and #1 does not. They are both strings. All column names *must* be of the same type. What was your CF definition ? Cheers - Aaron Morton Freelance Developer @aaronmorton http://www.thelastpickle.com On 6/07/2012, at 7:26 AM, Sunit Randhawa wrote:

HI Aaron, It is create column family CF with comparator = 'CompositeType(org.apache.cassandra.db.marshal.Int32Type,org.apache.cassandra.db.marshal.UTF8Type,org.apache.cassandra.db.marshal.UTF8Type)' and key_validation_class = UTF8Type and default_validation_class = UTF8Type;
