Subject: Key cache capacity: 1 when using KeysCached="50%"
I've noticed that when defining KeysCached="50%" (or KeysCached="100%" and I
didn't test other values with %) then cfstats reports Key cache capacity: 1
This looks weird... is this expected? (version 0.6.1)
For example, in the default configuration:
<ColumnFamily Name="Super2"
ColumnType="Super"
CompareWith="UTF8Type"
CompareSubcolumnsWith="UTF8Type"
RowsCached="10000"
KeysCached="50%"/>
