Viktor,
I will assume you are using 6.X.
In 6.X changes to cache capacity through JMX are NOT saved. Use the
KeysCached and RowsCached
<ColumnFamily Name="Super2"
ColumnType="Super"
CompareWith="UTF8Type"
CompareSubcolumnsWith="UTF8Type"
RowsCached="10000"
KeysCached="1111111"
Be warned the attributes are CaSe SeNSative!
