Thurs. 11/13 – “Deep Dive on Riak 2.0 Data Types”
Thu, Nov 13, 2014 8:00 AM – 9:00 AM PST
Thu, Nov 13, 2014 12:00 PM – 1:00 PM PSTRiak is an eventually consistent system. When handling conflicts, due to concurrent writes, in a distributed database the client application must have a way to resolve conflicts.
Riak Data Types give the developer the power of application modeling, while relieving them of the burden of designing and testing merge functions.
In this webinar we will provide an overview of Riak Data Types, the approach to adding them to Riak, and their usage in a practical application.
Wed. 11/19 – “Using Solr to Find Your Keys”
Wed, Nov 19, 2014 8:00 AM – 9:00 AM PST
Wed, Nov 19, 2014 12:00 PM – 1:00 PM PSTRiak 2.0 contains the next iteration of Riak Search, it pairs the strength of Riak as a horizontally scalable, distributed database with the powerful full-text search functionality of Apache Solr.
Reading the blog post at: http://basho.com/distributed-data-types-riak-2-0 will be good preparation for the first seminar.
From the post:
CRDT stands for (variously) Conflict-free Replicated Data Type, Convergent Replicated Data Type, Commutative Replicated Data Type, and others. The key, repeated, phrase is “Replicated Data Types”.
One strategy for avoiding data conflicts is normalization as we know from the relational world. Where normalization results in only one copy of any data. But that presumes human curation of the data structure that eliminates duplication of data.
Normalization isn’t a concern for distributed systems, which by definition can have multiple copies of the same data. But what happens when inconsistent duplicated data is combined together is the issue addressed by CRDTs (whatever your expansion).
If you think about it, topics that represent the same subject may well hold “inconsistent” data about that subject. Data that is present on one topic and absent on the other. Or that is on both topics and is inconsistent. CRDTs offer a way to define automated handling of some forms of “inconsistency.”
