<br><br><div dir="ltr"><div><div>Hello everyone!<br><br></div>Today I'm faced with unexpected Cassandra behavior. Please keep in mind that if you execute UPDATE query end set all fields to null (or empty collections for collection type) it can delete your record, but also it can only set values to null and keep record alive. It depends on how to record was created: using insert query or update query. Please take a look at reproduce steps here <a href="https://gist.github.com/dukhlov/11195881" target="_blank">https://gist.github.com/dukhlov/11195881</a>.<br>
</div>FYI: Cassandra 2.0.7 has been released. As we know there were some fixes for condition operation and batch operations which are necessary for us. So It would be nice to update magnetodb devstack to use Cassandra 2.0.7<span class="HOEnZb"><font color="#888888"><br clear="all">
