Because for small columns the Java "container" objects are larger than
the actual column data.

flush of Memtable-idx_graphable@915643571*(4671498/96780112
serialized/live bytes, 59891 ops)
can somebody explain why difference between live and serialized is so
big? Serialized bytes are actual bytes written to sstable?

Thanks Jonathan !
memtable_total_space_in_mb is the threshold that is reached.
Kind regards,

Hi,
I've checked the memtable flush (cassandra 0.8.4) and it seams to me it
hapens sooner then the threshold is reached.
Here's the threshould's (the default ones calculated for a heap size of
-Xmx1980M):
ColumnFamily: idx_graphable (Super)
Key Validation Class: org.apache.cassandra.d

I am in the process of trying to tune the memtable flush thresholds for a
particular column family (super column family to be specific) in my
Cassandra 0.8.1 cluster. This CF is reasonably heavily used and getting
flushed roughly every 5-8 minutes which is hardly optimal, particularly
given I have
