Hi!
Just wondering why this doesn't already exist: wouldn't it make sense to have
decorating data types that compress (gzip, snappy) other data types (esp.
UTF8Type,
AsciiType) transparently?

Any JSON (well, probably anything with quotes...) breaks it:
{
74657374: [[data, {foo:bar}, 1308209845388000]]
}
[default@foo] set transactions[test][data]='{foo:bar}';
I feared that storing data
Guess this could simply be done in the quote() method.
{ 74657374: [[data, {foo:bar}, 1308209845388000]] }
Does this work?

Hi!
5 nodes, replication factor of 2, fifth node down.
As long as I write a single column with hector or pelops, it works. With 2
columns it fails
because there are supposed to few servers to reach quorum. Confusing. If I
decommission the fifth
node with nodetool quorum works again and I can

Hi!
What about a simple option for sstable2json to not print out expiration
TTL+LocalDeletionTime (maybe even ignore isMarkedForDelete)? I want to move old

expire there).
BTW is there a smarter way to do this? Actually

I had OOM problems
nodetool repair it held more
data than all other nodes. So it copied data from the other nodes to this one?
I assumed that data is replicated to q nodes not to all, is quorum 'only' about
consistency and not about saving storage space?

Hi!
I've 3 servers running (0.7rc1) with a replication_factor of 2 and use quorum
for writes. But when I shut down one of them UnavailableExceptions are thrown.
Why is that? Isn't that the sense of quorum and a fault-tolerant DB that it
continues with the remaining 2 nodes and redistributes
.
