Hi DuyHai,
Zitat von DuyHai Doan <doanduy...@gmail.com>:
Hello Peter
I'm working with Peter and am the one initiating the table creation in
my code.
For safe concurrent table creation, use CREATE TABLE xxx IF NOT EXISTS. It
unfortunately, my code already has the "IF NOT EXISTS" clause in the
create statement, but we see the exceptions nevertheless.
(I'll leave it to Peter to post his test case statements, if required,
since he has created an isolated test to reliably reproduce the
problem.)
will use light weight transaction and you'll have to pay some penalty in
term of performance but at least the table creation will be linearizable

Hi,
We use a four-node Cassandra-Cluster in Version 2.1.2. Our
Client-Applications creates Tables dynamically. At one point two (or more)
of our Clients connected to two (or more) different Cassandra-Nodes will
create the same table simultaneously. We get the "Column family ID
mismatch"-Error-Messages on every node. Why is this simultanous schema
modification not possible? How can we handle this? Every Help is
appreciated.

Jens
