------------------------------------------
Summary: Corruption in schema changes due to clock jumps
Key: CASSANDRA-14617
URL: https://issues.apache.org/jira/browse/CASSANDRA-14617
Project: Cassandra
Issue Type: Bug
Reporter: Garvit Juniwal
It seems like schema changes like CREATE/DROP TABLE can get swallowed or
re-ordered if there are clock jumps on the host. I am able to reproduce this on
version 3.0.9 by doing the following:
t = 10 CREATE TABLE foo
manually set the host clock to t = 5
t = 5 DROP TABLE foo
.. let time advance ..
t = 11 table foo still exists in schema
There does not seem to be a way to either provide user timestamps or use light
weight transactions for schema changes (at least not documented in to
[https://docs.datastax.com/en/cql/3.3/cql/cql_using/useInsertLWT.html] or
https://docs.datastax.com/en/cql/3.3/cql/cql_reference/cqlCreateTable.html)
