Brandon Williams commented on CASSANDRA-8937:
---------------------------------------------

Unfortunately this fails to compile for me:

{noformat}
    [javac] /home/drift/cassandra/src/java/org/apache/cassandra/metrics/KeyspaceMetrics.java:179:
error: cannot find symbol
    [javac]                 return (long) metric.liveSSTableCount.getValue();
    [javac]                                                      ^
    [javac]   symbol:   method getValue()
{noformat}

> We currently don't have liveSSTableCount metrics aggregated at keyspace level.  If many
sstables exists and we can't realize it earlier,  cassandra will oom while doing scanning
operations. It would be nice and easy to aggregate it.
