Subject [jira] [Commented] (CASSANDRA-8818) Creating keyspace then table fails with non-prepared query

Sotirios Delimanolis commented on CASSANDRA-8818:
-------------------------------------------------

Shouldn't the ConsistencyLevel of All account for that?

>             Project: Cassandra

> Hi, I'm not sure if this is a driver or cassandra issue, so please feel free to move
to the appropriate component. I'm using C# on mono (linux), and the 2.5.0 cassandra driver
for C#.  We have a cluster of 3 nodes, and we noticed that when we created a keyspace, then
a table for that keyspace in quick succession it would fail frequently. I put our approximate
code below.
> Additionally, we noticed that if we did a prepared statement instead of just executing
the query, it would succeed. It also appeared that running the queries from a .cql file (outside
of our C# program) would succeed as well. In this case with tracing on, we saw that it was
"Preparing statement".
> Please let me know if you need additional details. Thanks!
