Subject Re: [RELEASE] Apache Cassandra 3.0.10 released
Date Thu, 17 Nov 2016 12:05:37 GMT
Hi,

&gt;Does this mean that offheap_objects is still available or that there is no longer
support for offheap memtables in version 3.0?



If you  set offheap_buffers in cassandra.yaml in 3.0.10, you'll get exception 

offheap_buffers are not available in 3.0. They will be re-introduced in a future release,
see https://issues.apache.org/jira/browse/CASSANDRA-9472 for details

on Cassandra start.

&gt; Apache Cassandra is a fully distributed database. It is the right choice

&gt; when you need scalability and high availability without compromising

&gt; performance.

&gt; please pay attention to the release notes[2] and Let us know[3] if you

Hello,



>From the NEWS file:




3.0.10

=====

Upgrading

---------

   - memtable_allocation_type: offheap_buffers is no longer allowed to be specified in the
3.0 series.

     This was an oversight that can cause segfaults. Offheap was re-introduced in 3.4 see
CASSANDRA-11039

     and CASSANDRA-9472 for details.





Does this mean that offheap_objects is still available or that there is no longer support
for offheap memtables in version 3.0?
