What is substituting keys_cached column family argument

[Roman Yankin]

Problem:

If I do something like this in Cassandra 1.1.7 I would get IAE:
create column family travelers with keys_cached=1000000 and 
column_metadata=[{column_name: t, validation_class: UTF8Type, index_type: 
KEYS}];
java.lang.IllegalArgumentException: No enum const class 
org.apache.cassandra.cli.CliClient$ColumnFamilyArgument.KEYS_CACHED



In Cassandra v 0.7 there was a column family property called keys_cached, now 
it's gone and I'm struggling to understand which of the below properties it's 
now substituted (if substituted at all)?

The below snippet comes from org.apache.cassandra.cli.CliClient class from 
source v 1.1.7 

protected enum ColumnFamilyArgument
    {
        COLUMN_TYPE,
        COMPARATOR,
        SUBCOMPARATOR,
        COMMENT,
        READ_REPAIR_CHANCE,
        DCLOCAL_READ_REPAIR_CHANCE,
        GC_GRACE,
        COLUMN_METADATA,
        MEMTABLE_OPERATIONS,
        MEMTABLE_THROUGHPUT,
        DEFAULT_VALIDATION_CLASS,
        MIN_COMPACTION_THRESHOLD,
        MAX_COMPACTION_THRESHOLD,
        REPLICATE_ON_WRITE,
        KEY_VALIDATION_CLASS,
        COMPACTION_STRATEGY,
        COMPACTION_STRATEGY_OPTIONS,
        COMPRESSION_OPTIONS,
        BLOOM_FILTER_FP_CHANCE,
        CACHING
    }

Thanks,
