Hi, I have a cluster spreaded among 2 datacenters (DC1 and DC2), two server on each DC and I have a keyspace with NetworkTopologyStrategy (DC1:2 and DC2:2) with the following table:
CREATE TABLE test ( k1 int, k2 timeuuid, PRIMARY KEY ((k1), k2) ) WITH CLUSTERING ORDER BY (k2 DESC) During a datacenter outage, as soon as a datacenter goes offline, I get this error during a lightweight transaction: cqlsh:devtest> insert into test (k1,k2) values(1,now()) if not exists; Request did not complete within rpc_timeout. And a short time after the on-line DC verify the second DC is off-line: cqlsh:devtest> insert into test (k1,k2) values(1,now()) if not exists; Unable to complete request: one or more nodes were unavailable. So, my question is: Is there any way to keep lightweight transactions working during a datacenter outage using the C* Python driver 2.7.2 ? I was thinking about catch the exception and do a simple insert (without "IF") when the error occur, but having the lightweight transactions working even during a DC outage/split would be nice. Thanks in advance for any help/hints. Best regards, Jero
