Hello Gang,
For your perusing this weekend we’ve got a few announcements along with the always informative mailing list recap. New bits to download while you enjoy fall weather (not if you live in Texas though…) As always, let us know your thoughts: If you’re working on or speaking about something Riak related and would like a mention, let me know. I’ll get your talk, project or blog post in the next Riak Recap. I know a guy. ## Announcements - Riak Spark Connector 1.6.0 [0] brings a number of feature enhancements and a wealth of documentation [1]. If you’re working with either Riak or Spark, take a look at how you can work with both of them together. - Riak Mesos Framework 1.3.0 [2] gets bumped to Mesos 1.0 support among a number of other enhancements. Take a look at the latest Scheduler [3], Executor [4], and Explorer [5] under the hood. - Gordon Guthrie, esteemed Basho engineer, delivers a talk at Erlang User Conference [6] entitled “From NoSQL to Mo' SQL - Adding Structure and Queriability to Riak” [7]. An in depth background on Riak TS from the fount himself. - The Riak IoT Roadshow [8] is coming to a city near you. Come learn about IoT and how you can service those use cases with Riak TS: - Chicago, Sept 27th [9] - Stockholm, Sept 27th [10] - London, October 5th [11] - Atlanta, October 6th [12] ## Jobs at Basho Interested in working on distributed computing related problems or helping our community with theirs? We’re hiring, here are a few of our open positions. Check out the rest [13]. - Client Services Engineer (London) [14]. - Developer Advocate EMEA (London) [15]. - Developer Advocate (US) [16]. - Solution Architect (SF) [17]. (Yes, a number of these positions are remote.) ## Recently Answered - Kyle Nguyen is working through some certificate based auth issues with the Java client [18]. Luke Bakken and others provide a bunch of interesting ssl debug information in this thread. - Travis Kirstine is looking for ways to speed up bulk loading [19]. Matthew von-Maszewski [20] links an interesting article on Erlang VM scheduler optimization [21], Guido Medina considers adjusting some tunable parameters [22] and I want to confirm that the load is being distributed through a proxy [23]. - Ricardo Mayerhofer want to process data from Riak KV with Amazon ML by exporting data into a csv file and store it in S3 [24]. Matt Digan reminds us that Riak KV does not support full bucket scan natively but recommends Riak TS or a 2i index in KV [25]. - Sean McEvoy is interested in searching strings with spaces in them [26]. Not entirely as trivial as one would hope [27] [28]. - Alan got an odd error when using the PHP client [29]. Luke reminds us that certain KV features are not supported in TS [30], yet… - Weixi Yen writes in with an issue with multiple copies of an object getting returned in Solr queries [31]. This is what happens when you query the Solr nodes directly [32]. Don’t do that :( - Joris van Agtmaal is working to access a Riak TS cluster from a Zeppelin notebook [33]. The trick, because there always is one, is to load the uber jar [34][35]. - Alex De la rosa wants to secure Riak behind a firewall [36]. John Daily links the security page of our documentation [37] and Alex succinctly summarizes it [38] for confirmation. - As a follow up, Magnus Kessler lets Alex know that the correct place to limit Erlangs dist ports is in riak.conf [39]. - Vipin Sharma finds an issue in how Riak implements coverage queries in conjunction with cursor mark queries in Solr [40]. Fred Dushin notes that this is an area for improvement in Riak potentially involving pinning a coverage plan to a query [41]. ## Open Discussions - Guillaume Boddaert is looking for info on re-indexing Solr indexies [42], Fred Dushin fills in some details [43]. Still, questions remain [44] . - Anthony Valenti is asking if someone’s gotten Hadoop to access Riak CS via S3 [45]. - John is looking for info on memory reclamation when using the memory backend and max memory setting [46]. - Travis Kirstine is looking for help with enotconn errors in Riak when connecting through haproxy [47]. - Matthew Daiter asks for some help getting Riak CS up on NixOS [48]. Anybody out there have NixOS experience? - Sean McEvoy wants to get some more performance out of paginated queries in Solr [49]. Fred Dushin lets us know that cursor marks are the way to go [50]. Unfortunately, the front-end guys always want more [51]. - Lingesh is getting an error when starting Riak and enabling AAE due to 100% i/o utilization [52]. - Following up on previous Solr query, cursor mark and coverage plan discussions, Guillaume Boddaert opens a new line of questioning around tuning the coverage plan itself [53].
