If I have a table like this: PRIMARY KEY ((userid),deviceid)
And I query SELECT * FROM devices where userid= ? and deviceid = ? Will cassandra read the entire partition for the userid? So if I lots of tombstones for userid, will they get scanned? I guess this depends on how the bloomfilter is working. Does it contain partitioning key or primary key? We're using 2.0.17 if it matters. /Oskar
