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

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.

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,
that is why your each sstable is 5MB. And if you dataset is huge, you will

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 faster (> x100) than we would in a
production environment. This has left the Column F
