Querying composite keys
Hello I have key and columns defined in following fashion: HotelName1:RoomNum1 HotelName2:RoomNum2 HotelName3:RoomNum3 Key1:TimeStamp:VersionNum Is there a way that I can query this schema by only 'key' or 'HotelName' i.e. querying using a part of composite key and not the full key.

RE: Accessing Metadata of Column Familes
I found following issues while working on Cassandra version 1.2, CQL 3 and Thrift protocol 19.35.0. Case 1: Using CQL I created a table t1 with columns col1 and col2 with col1 being my primary key. When I access same data using CLI, I see col1 gets adopted as rowkey and col2 being another column. Now I have inserted value in another column (col3) in same row using CLI. Now when I query same table again from CQL I am unable to find col3. Case 2: Using CLI, I have created table t2. Now I added a row key row1 and two columns (keys) col1 and col2 with some values in each. When I access t2 from CQL I find following resultset with three columns: key | column1 | value row1| col1 | val1 row1| col2 | val2 This behavior raises certain questions: * What is the reason for such schema anomaly or is this a problem? * Which schema should be deemed as correct or consistent? * How to access meta data on the same?

After clearing the system files I was able to successfully join the node. thanks.

The joining node is unable to discover the cluster information it needs to find the correct place to join. However there code appears to have checks in place to prevent that from happening. If you have time can you please try to reproduce the fault ? * set logging to DEBUG on /etc/cassandra/log4j-server.properties * clear all files from /var/lib/cassandra/data/system * start the node I *think* if you restart the node it will work as it will used stored load data.

RE: cli question
I faced the same issue some time back. Solution which fit my bill is as follows:
CREATE COLUMN FAMILY aaa
with comparator = 'CompositeType(UTF8Type,UTF8Type)'
and default_validation_class = 'UTF8Type'
and key_validation_class = 'CompositeType(UTF8Type,UTF8Type,UTF8Type,)';
notice I have mentioned three datatypes or validators in key_validation_class
under CompositeType.
Now if I have to insert with key aaa:bbb:ccc it will work smoothly and even if
I wish to insert with just aaa:bbb it will work just fine.
Do let me know if it solves your problem.

Hi!
I have CF with the following deffinition:
CREATE COLUMN FAMILY a_b_indx
with comparator = 'CompositeType(LongType,UUIDType)'
and default_validation_class = 'UTF8Type'
and key_validation_class = 'CompositeType(UTF8Type,UTF8Type)';
Where the key may be a composite of the following two strings: 'AAA' and
'BBB:CCC'
Notice, that the second string has ':' in it.
I try to query for rows I know exist in the CF but can't.
I tried those and many more :)
* get a_b_indx ['AAA:BBB:CCC'];
* get a_b_indx ['AAA:BBB\:CCC'];
* get a_b_indx [utf8('AAA'):utf8('BBB:CCC')];
Is it possible? Does anyone know how?
