What does "show schema" show? Is the CF showing up?
Are the data files for the CF on disk?
If you poke around with the system CFs, is there any data still present?

In Cassandra you don't read-then-write updates, you just write the updates.
Sorry for being dense, but can you clarify a logical vs. physical row?
Batching is useful for reducing round trips to the server.

It will still be a no look write. The exception being secondary
indexes and counters which include reads in the write path.

Depending on your needs, you could simply duplicate the comments in two
separate CFs with the column names including time in one and the vote in
the other. If you allow for updates to the comments, that would pose
some issues you'd need to solve at the app level.

Somewhat recently the Ownership column was changed to Effective
Ownership.
Previously the formula was essentially 100/. Now it's
100*/. So in previous releases of Cassandra
it would be 100/12 = 8.33, now it would be closer to 25% (8.33*3
(assuming a replication factor of three)).

The tricky thing with documenting the SS tables is that there are a lot
of conditionals in the structure, so it makes for twisty reading. Just
for fun, here's a terrible start I made once:

Disclaimer: I've never tried, but I'd imagine you can drop a JAR
containing the class(es) into the lib directory and perform a rolling
restart of the nodes.

o the code and run some tests, but I was curious about
how to quantify the overhead of a column family. Is the reason performance?
Memory? Does the off-heap work help here?
