Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects.

<p>PredictionIO has a thin storage layer to abstract meta data, event data, and model data access. The layer defines a set of standard interfaces to support mul tiple data store backends. PredictionIO users can configure the backend of choice through configuration files or environmental variables. Engine developers need not worry about the actual underlying storage architecture. Advanced developers can implement their own backend driver as an external library.</p><h2 id='concepts' class='header-anchors'>Concepts</h2><p>In this section, we will visit some storage layer concepts that are common to users, engine developers, and advanced developers:</p> <ul> <li><p><strong>Repository</strong> is the highest level of data access abstraction and is where all engines and PredictionIO itself access data with.</p></li> <li><p><strong>Source</strong> is the actual data store backend that provide data access.

The following is an outline of how this can be achieved.</p> <ol> <li><p> Create an SBT project with a library dependency on PredictionIO's data access base traits (inside the <code>data</code> artifact).</p></li> <li><p> Implement traits that you intend to support, and package everything into a big fat JAR (e.g. sbt-assembly).</p></li> <li><p> Create a directory named <code>plugins</code> inside PredictionIO binary installation.</p></li> <li><p> Copy the JAR from step 2 to <code>plugins</code>.</p></li> <li><p> In storage configuration, specify <code>TYPE</code> as your complete package name. As an example, if you have implemented all your traits under the package name <code>org.mystorage.jdbc</code>, use something like</p><div class="highlight shell"><table style="b order-spacing: 0"><tbody><tr><td class="gutter gl" style="text-align: right"><pre class="lineno">1 +2 +3</pre></td><td class="code"><pre><span class="nv">PIO_STORAGE_SOURCES_MYJDBC_TYPE</span><span class="o">=</span>org.mystorage.jdbc +... +<span class="nv">PIO_STORAGE_REPOSITORIES_METADATA_SOURCE</span><span class="o">=</span>MYJDBC +</pre></td></tr></tbody></table> </div> <p>to instruct PredictionIO to pick up <code>StorageClient</code> from the appropriate package.</p></li> <li><p> Now you should be able to use your custom source and assign it to different repositories as you wish.</p></li> </ol> </div></div></div></div><footer><div class="container"><div class="seperator"></div><div class="row"><div class="col-md-6 footer-link-column"><div class="footer-link-column-row"><h4>Community</h4><ul><li><a href="//predictionio.incubator.apache.org/install/" target="blank">Download</a></li><li><a href="//predictionio.incubator.apache.org/" target="blank">Docs</a></li><li><a href="//github.com/apache/incubator-predictionio" target="blank">GitHub</a></li><li><a href="mailto:[email protected]"; target="blank">Subscribe to User Mailing List</a></li><li><a href="//stackoverflow.com/questions/tagged/predictionio" target="blank">Stackoverflow</a></li></ul></div></div><div class="col-md-6 footer- link-column"><div class="footer-link-column-row"><h4>Contribute</h4><ul><li><a href="//predictionio.incubator.apache.org/community/contribute-code/" target="blank">Contribute</a></li><li><a href="//github.com/apache/incubator-predictionio" target="blank">Source Code</a></li><li><a href="//issues.apache.org/jira/browse/PIO" target="blank">Bug Tracker</a></li><li><a href="mailto:[email protected]"; target="blank">Subscribe to Development Mailing List</a></li></ul></div></div></div><div class="row"><div class="col-md-12 footer-link-column"><a class="pull-right" href="http://incubator.apache.org/projects/predictionio.html";><img alt="Apache Incubator" src="/images/logos/apache_incubator-6954bd16.png"/></a><span>Apache PredictionIO is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communica tions, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</span></div></div></div><div id="footer-bottom"><div class="container"><div class="row"><div class="col-md-12"><div id="footer-logo-wrapper"><img alt="PredictionIO" src="/images/logos/logo-white-d1e9c6e6.png"/></div><div id="social-icons-wrapper"><a class="github-button" href="https://github.com/apache/incubator-predictionio"; data-style="mega" data-count-href="/apache/incubator-predictionio/stargazers" data-count-api="/repos/apache/incubator-predictionio#stargazers_count" data-count-aria-label="# stargazers on GitHub" aria-label="Star apache/incubator-predictionio on GitHub">Star</a> <a class="github-button" href="https://github.com/apache/incubator-predictionio/fork"; data-icon="octicon-git-branch" da ta-style="mega" data-count-href="/apache/incubator-predictionio/network" data-count-api="/repos/apache/incubator-predictionio#forks_count" data-count-aria-label="# forks on GitHub" aria-label="Fork apache/incubator-predictionio on GitHub">Fork</a> <script id="github-bjs" async="" defer="" src="https://buttons.github.io/buttons.js";></script><a href="https://twitter.com/predictionio"; target="blank"><img alt="PredictionIO on Twitter" src="/images/icons/twitter-ea9dc152.png"/></a> <a href="https://www.facebook.com/predictionio"; target="blank"><img alt="PredictionIO on Facebook" src="/images/icons/facebook-5c57939c.png"/></a> </div></div></div></div></div></footer></div><script>(function(w,d,t,u,n,s,e){w['SwiftypeObject']=n;w[n]=w[n]||function(){ +(w[n].q=w[n].q||[]).push(arguments);};s=d.createElement(t); +e=d.getElementsByTagName(t)[0];s.async=1;s.src=u;e.parentNode.insertBefore(s,e); +})(window,document,'script','//s.swiftypecdn.com/install/v1/st.js','_st'); + +_st('install','HaUfpXXV87xoB_zzCQ45');</script><script src="/javascripts/application-a6acb1f5.js"></script></body></html> \ No newline at end of file http://git-wip-us.apache.org/repos/asf/incubator-predictionio-site/blob/32eb5edf/system/anotherdatastore/index.html.gz ---------------------------------------------------------------------- diff --git a/system/anotherdatastore/index.html.gz b/system/anotherdatastore/index.html.gz new file mode 100644 index 0000000..fdaa128 Binary files /dev/null and b/system/anotherdatastore/index.html.gz differ
