So coming back to the query language, you either simulate OO queries,
which Thrift already does as badly as can be expected, or you drop down
to multiple strings, which IMHO is a bad compromise, or you use a single
string like most universal APIs

i'm trying to understand why cassandra 0.5 RC3 is behaving like it is.
I have a 5 node cluster, RF=3, W=ALL, R=1. all is well if all the nodes
are running. if i remove a node, then puts fail - doesn't matter
which host i'm connected to. if i restart the node, then all goes back
to normal

that makes sense, but i have had trouble understanding why
hinted-handoff doesn't take care of it? if not, how many nodes would i
need to prevent this?

use quorum reads and writes instead of ALL on writes if you need both
consistency and availability

so with 5 node cluster, R=W=Q and RF=3, i can only loose one consecutive
node on the consistency ring, correct?

so i changed to QUORUM and retested. puts again work as expected when
a node is down. thx!
however, the response time for puts went from about 5ms to 400ms because
i took 1 of the 5 nodes out. ROW-MUTATION-STAGE pendings jumped into to
100's on one of the remaining nodes and the WriteLatency

That's a thrift error -- if you have your python thrift in sync with
the version the server is running then it must be a thrift bug.
