I have a column family defined as:
create column family LSItemIdsByFieldValueIndex_Integer
with column_type = 'Standard'
and comparator =
'CompositeType(org.apache.cassandra.db.marshal.IntegerType,org.apache.cassandra.db.marshal.UTF8Type)'
and default_validation_class = 'UTF8Type'
and
in case you do not know yet, opscenter is sending certain data about
your cassandra instalation back to datastax.
This fact is not visibly presented to user, its same spyware crap like
EHCache.

Hi,
We are trialling Cassandra-1.2(.4) with Leveled compaction as it looks
like it may be a win for us.
The first step of testing was to push a fairly large slab of data into the
Column Family - we did this much

With LeveledCompaction, each sstable size is fixed and is defined by
sstable_size_in_mb in the compaction configuration of CF definition and
default value is 5MB. In you case, you may have not defined your own value,
Not in the case of LeveledCompaction. Only SizeTieredCompaction merges
smaller sstables into large ones. With the LeveledCompaction, the sstables
are always of fixed size but they are grouped into different levels.

default value of 5MB is way too small in practice. Too many files in one
directory is not a good thing. It's not clear what should be a good number. I
have heard people are using 50MB, 75MB, even 100MB. Do your own test o find a
right number.

Correction, the largest I heard is 256MB SSTable size.
