Vijay commented on CASSANDRA-1311:
----------------------------------
Hi Jonathan,
Removed LinkedList allocation in v3 and pushed to
https://github.com/Vijay2win/cassandra/commits/1311-v3
{quote}
Let's also create follow-up tickets for loading new triggers from the directory
at runtime
{quote}
we already have JMX to reload from the filesystem and CASSANDRA-4949
I posted the sample to https://github.com/Vijay2win/inverted-index, i am really
happy to move it to contrib, will address it in a different ticket.
If everything else is fine i will get this committed to 2.0.
