Sylvain Lebresne commented on CASSANDRA-3929:
---------------------------------------------
bq. How would you use this filter interface to implement something
CQL-row-aware?
I'm not sure honestly. I was suggesting that as a simpler alternative to
modifying the compaction strategy API, which wouldn't be easily CQL-aware
either because both solution involve dealing with the internal storage engine.
Now, it would be possible to write something CQL-aware with the filter
interface above (except maybe that we might want to provide the CFMetaData
object too), but that would have to be done manually (typically using the
ColumnCounter class, you could reasonably easily start "dropping" columns once
you reach the nth CQL-row).
