## Recently Answered


   Saran was able to fix his Solr not starting issue [7] by correcting the
   internal ip address in the configuration file [8].

   Because Riak is written in Erlang you are able to modify a number of
   config parameters without bouncing the VM. Nevertheless, there are a few
   parameters that can not be changed without a bump. Luke confirms Edgar’s
   concerns that, at the moment, changing an ip address requires a reboot of
   the Erlang virtual machine [9].

   Fasil is looking for ways to remotely configure bucket types [10].
   Vitaly confirms that certain operations are only available via the command
   line and not in the API [11].

   Jim is experiencing a particular flavor of Solr timeouts [12] which Fred
   pinpoints to certain areas in the code and recommends making changes to
   hard coded timeouts [13]. Jim verifies the issue but is unhappy about
   making those changes, testing continues with a new JVM version [14].

   Alex was having some issues testing against his single node cluster
   [15]. Luke verified that the ring file needed to be reset [16].

   In case you were wondering, Riak S2 is the same as Riak CS [17]. Riak CS
   has been rebranded Riak S2.

   Luke helps Satish work through some ulimit issues [18]. Riak noms fd’s…
   feed it!

   Surajit found a broken link in the docs [19]. The documentation team
   always welcomes community feedback. If you see something - say something!

   Jared is looking for enhancements to the .NET client [21]. Luke drops
   him an example and lets us know that enhancements are on the way in the
   next version [22].

   Shifeng is looking for details on how to delete and reclaim used disk in
   Riak [23]. Alexander (me!) answers with additional food for thought [24].

   Harjot has some requirements for his time series related project and is
   looking for some feedback on the Riak TS product roadmap [25]. Seema,
   Director of Product at Basho lets us know what’s coming up next [26]. If
   you have a project that needs certain features - let us know!

## Open Discussions


   In this long running thread Fred drops some Erlang which gets the build
   times of individual partition hash trees to help debug Oleksiy’s
   inconsistent Solr search results [27].

   Alex is looking for advice regarding whether or not Riak TS would be
   better suited in certain use cases over Riak KV for his social network
   project [28].

   Fred asks Anil for more details on his solr duplicate records issue [29].

   Luke is looking for more information from Joe on his indexing design
   question [30].

   Michael is looking for some guidance on properly sizing a Riak S2
   cluster [31].
