Hi,
i am a little puzzled on creation of secondary indexes and the docs in that
area are still very sparse.
What I am trying to do is - in a columnfamily with TimeUUID comparator, I want
the "special" timeuuid 00000000-0000-1000-0000-000000000000 to be indexed. The
value being some UTF8 string on which I want to perform equality checks.
What do I need to put in my cassandra.yaml file?
Something like this?
- column_metadata: [{name: 00000000-0000-1000-0000-000000000000,
validation_class: UTF8Type, index_name: MyIndex, index_type: KEYS}]
This gives me that error:
15:05:12.492 [pool-1-thread-1] ERROR o.a.c.config.DatabaseDescriptor - Fatal
error: null; Can't construct a java object for
tag:yaml.org,2002:org.apache.cassandra.config.Config; exception=Cannot create

JavaBean=org.apache.cassandra.config.RawColumnDefinition@e29820; Unable to find
property 'validation_class' on class:
org.apache.cassandra.config.RawColumnDefinition
Bad configuration; unable to start server
I am furthermor uncertain if the column name will be correctly used if given
like this. Should I put the byte representation of the uuid there?
Greetings,
roland
