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:

was curious about
how to quantify the overhead of a column family. Is the reason performance?
Memory? Does the off-heap work help here?
Thanks,

1. ability to wholesale drop data for a given tenant via drop
keyspace/drop CFs
2. ability to have divergent schema

Hi all,
On an unrelated observation of the below readings, it looks like all
the 3 nodes own 100% of the data. This confuses me a bit. We have a 12
node cluster with RF=3 but the effective ownership is shown
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.

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

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.
