--------------------------------------------
Summary: RowUpdateBuilder is broken for maps and lists
Key: CASSANDRA-9743
URL: https://issues.apache.org/jira/browse/CASSANDRA-9743
Project: Cassandra
Issue Type: Bug
Reporter: Aleksey Yeschenko
Assignee: Sylvain Lebresne
Fix For: 3.0 beta 1
Something's not right with {{RowUpdateBuilder}} when adding map or list
entries. It breaks {{SELECT}} queries that follow afterwards, inflating the
resultset, and duplicating the rows multiple times.
It manifests when a table has more than one collection, and we update them both
with more than one item.
Here is a gist with minimal reproducible code:
https://gist.github.com/iamaleksey/b6e9476fece029067729
The bug is currently blocking CASSANDRA-6717 code for migration from old schema
keyspace to a new one.
P.S. I'm assuming that the bug is in {{RowUpdateBuilder}} because I couldn't
reproduce in cqlsh. Could be that something's broken in the iterators, but
trying to debug a cascade of them failed me.
