Yes but adding the extra one ends up by * 1000. The limit in CQL3 specifies
the number of logical rows, not the number of physical columns in the
storage engine

oh.. the difference between the the ONE field and the remaining 29 is
massive.
It's like 200ms for just the 29 columns.. adding the extra one cause it to
timeout .. > 5000ms...

Don't forget that when you do the Select with limit set to 1000, Cassandra
is actually fetching 1000 * 29 physical columns (29 fields per logical
row).
Adding one extra big html column may be too much and cause timeout. Try to:
1. Select only the big html only
2. Or reduce the limit incrementally
I have a table with a schema mostly of small fields. About 30 of them.
The primary key is:
primary key( bucket, sequence )
… I have 100 buckets and the idea is that sequence is ever increasing.
This way I can read from bucket zero, and everything after sequence N and
get all the writes ord
