RavenDB vs MongoDB: Which is Better? This White Paper compares the two leading NoSQL Document Databases on 9 features to find out which is the best solution for your next project.  

Cassandra validates column names and row keys using validation classes.
This is put in place when you construct a columnFamily.

As an example, in the Thrift API:
CfDef columnFamily = new CfDef(KEYSPACE, COLUMN_FAMILY);
columnFamily.setKey_validation_class("UTF8Type");
columnFamily.setDefault_validation_class("UTF8Type"); 
The default_validation_class is used to validate row keys.
The key_validation_class is used to validate column names.

Googling didn't provide a handy list of validation classes for Cassandra.
So, here it is:

AsciiType.java BooleanType.java 
BytesType.java 
CompositeType.java 
DateType.java 
DecimalType.java 
DoubleType.java 
DynamicCompositeType.java 
FloatType.java 
Int32Type.java 
IntegerType.java 
LexicalUUIDType.java 
LocalByPartionerType.java 
LongType.java 
ReversedType.java 
TimeUUIDType.java 
TypeParser.java 
UTF8Type.java 
UUIDType.java
