I suggest reading the native protocol spec:
https://github.com/apache/cassandra/blob/trunk/doc/native_protocol_v3.spec
The native protocol is not RPC. One of the reasons why it is more
efficient than thrift is that multiple operations can be in flight at the
same time with a single connection.

Hi folks,
I'm working on a project that might benefit from Cassandra's
compare-and-swap operations, and we're wondering about whether there are
plausible corner cases under which linearizable consistency semantics
aren't maintained by the implementation. In particular, we're
interested in how Cas
I'm bias in favor of using both thrift and CQL3, though many people on the
list probably think I'm crazy.
CQL3 is good if what you need fits nicely in static columns, but it doesn't
if you want to use dynamic columns and/or mix & match both in the same
columnFamily. For a lot of what I use Cassand
Thanks, Ryan. I wasn't aware of static column support, and indeed they get
me most of what I need. I think the only potential inefficiency is still
at query time. Using Thrift, I could design the column family to get the
all the static and dynamic content in a single query.
If event_source and
Hi,
just a follow up. We've seen this behavior multiple times now. It seems
that the receiving node loses connectivity to the cluster and thus
thinks that it is the sole online node, whereas the rest of the cluster
thinks that it is the only offline node, really just after the streaming
is over. I
Thanks guys.
I think I'll start with the replacement of a dead node procedure at least
for the first node and I'll monitor the cluster overhead and timing.
If I'll see that the overhead and elapsed time are substantially higher
I'll try to find some network storage to store the backup.
