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 property=keyspaces for JavaBean=org.apache.cassandra.config.Config@7eb6e2; Cannot create
property=column_families for JavaBean=org.apache.cassandra.config.RawKeyspace@987a33; Cannot
create property=column_metadata for JavaBean=org.apache.cassandra.config.RawColumnFamily@716cb7;
Cannot create property=validation_class for 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
