Gustavo, The middleware application is something you should build. I recommend building the majority of your application logic, including the use of the riak java client, in a server side java application. Expose any features your Android application needs via an authenticated API. John On Thu,

Timo, When you say Riak is reading data continuously, are you referring to the AAE trees being rebuilt? I just want to confirm that you did remove the anti_entropy directory, as not removing it can cause additional repair operations to occur. AAE can be enabled / disabled via riak attach with r

Toby, Were you running with AAE disabled until 1.4.8 was released? If so, AAE is likely repairing objects that needed to be read repaired during that time. Thanks, John On Tue, Feb 25, 2014 at 11:02 PM, Toby Corkindale wrote: > Hi, > After upgrading to 1.4.8 in staging, last week, we've bee

. It's also important to keep in mind that if you're performing these deletes to reclaim disk space, you will likely increase disk usage in the short term. Both Bitcask and LevelDB are append only backends, with merging / compaction processes that are triggered in the background. Thanks, Jo

Matt, How often is this MapReduce query being run? Is the execution of this MapReduce query done in a controlled manner (for instance, not initiated by users of your application)? The actual use case of MapReduce queries are important in determining Thanks, John Caprice On Mon, Mar 25

Re: Getting multiple values: is iterating or MapReduce preferred?

2013-03-25 Thread John Caprice
Rob, Performing GET requests either serially or concurrently is more efficient than using MapReduce to query for values. MapReduce has additional overhead that GET requests do not have. One example of this is that a GET is sent to only the nodes in the prefs list for a given key, while a MapRedu
