Note: required element

Attributes:
  1) keyspace [required] - specifies keyspace for Cassandra tables which should be used to store key/value pairs
  2) table    [required] - specifies Cassandra table which should be used to store key/value pairs
  3) ttl      [optional] - specifies expiration period for the table rows (in seconds)

    Specifies persistent settings for Ignite cache keys.

    Note: required element

    Attributes:
      1) class      [required] - java class name for Ignite cache key
      2) strategy   [required] - one of three possible persistent strategies:
            a) PRIMITIVE - stores key value as is, by mapping it to Cassandra table column with corresponding type.
                Should be used only for simple java types (int, long, String, double, Date) which could be mapped
                to corresponding Cassadra types.
            b) BLOB - stores key value as BLOB, by mapping it to Cassandra table column with blob type.
                Could be used for any java object. Conversion of java object to BLOB is handled by "serializer"
                which could be specified in serializer attribute (see below).
            c) POJO - stores each field of an object as a column having corresponding type in Cassandra table.
                Provides ability to utilize Cassandra secondary indexes for object fields.
      3) serializer [optional] - specifies serializer class for BLOB strategy. Shouldn't be used for PRIMITIVE and
        POJO strategies. Available implementations:
            a) org.apache.ignite.cache.store.cassandra.serializer.JavaSerializer - uses standard Java
                serialization framework
            b) org.apache.ignite.cache.store.cassandra.serializer.KryoSerializer - uses Kryo
                serialization framework
      4) column     [optional] - specifies column name for PRIMITIVE and BLOB strategies where to store key value.
        If not specified column having 'key' name will be used. Shouldn't be used for POJO strategy.
