+
+<p>An nt:resource child node is normally used instead of a plain binary property when more resource metadata is required.</p>
+
+<p>The <code>jcr:mimeType</code> property specifies the <a href="http://www.iana.org/assignments/media-types/" class="external-link" rel="nofollow">content type</a> of the resource, and the optional <code>jcr:encoding</code> specifies the <a href="http://www.iana.org/assignments/character-sets" class="external-link" rel="nofollow">character encoding</a> of text-based content types.</p>
+
+<p>The resource content is stored as a binary stream in the <code>jcr:data</code> property that is also the primary property of the node. The <code>jcr:lastModified</code> should be updated whenever the resource is modified.</p>
+
+<h2 id="Nt-resource-Relatednodetypes">Related node types</h2>

+<p>An Oak blob store is an optional storage component for storing large binary values. It is similar in concept to the Jackrabbit 2.x <a href="DataStore_115513387.html">official documentation</a>] with some enhancements as described in the [<a href="https://jackrabbit.apache.org/oak/docs/plugins/blobstore.html" class="external-link" rel="nofollow">https://jackrabbit.apache.org/oak/docs/plugins/blobstore.html</a>.</p>
+
+<p>This page is for development purposes to capture and collaborate on Oak blob store ideas in development. Once implemented the official docs should be updated accordingly.</p>
+
+<h2 id="OakBlobStores-CloudBlobStores">Cloud Blob Stores</h2>
+<p>Cloud blob stores are Oak blob store implementations that store blobs in cloud storage via a cloud storage API. The following blob store implementations are currently available in Oak (as of 1.6):</p>
+<ul>
+ <li>S3 Data Store</li>
+ <li>Azure Data Store
+<br class="atl-forced-newline"/></li>
+</ul>
+
+
+<p>Possible future work in this area could include blob stores for Google Cloud Storage or <a class="createlink" href="/confluence/pages/createpage.action?spaceKey=JCR&title=OpenStack&linkCreation=true&fromPageId=115513470">OpenStack</a>. Work on a generic cloud blob store using e.g. <a href="https://jclouds.apache.org/" class="external-link" rel="nofollow">JClouds</a> has been started and could be formalized.</p>
+
+<h2 id="OakBlobStores-CompositeBlobStores">Composite Blob Stores</h2>
+<p>A <a href="Composite-Blob-Store_115513379.html">Composite Blob Store</a> is a logical blob store that performs the blob storage functions via at least two other blob stores, based on configuration. The blob stores used by the composite blob store to perform the storage functions are called <em>delegate</em> blob stores. Composite blob stores must act as a single logical blob store to the rest of Oak, with all the implementation hidden within the context of the composite blob store.</p>

It will start Tuesday September 25 at 9:00 (one day before the conference starts). In this hackathon we want to improve the Oak code base, but also give an opportunity for newcomers to learn about the project and take first steps. If there is interest the Oak hackathon can be extended as a side track during the whole conference.</p>

Half of the roughly 10 attendees where new to the project so we decided to turn this more into an intro session. Jukka and Michael gave a preview on their <a href="https://docs.google.com/presentation/pub?id=1Au_l3bQ2XEhM4nZ9fftOz8MuBcnhDguW3so_QcrxlMw&start=false&loop=false&delayms=3000" class="external-link" rel="nofollow">Oak presentation</a> for .adaptTo 2012 and Jukka went through some coding examples showing how to write a custom commit hook for Oak.

+ <p>From the oak-dev@ list, here's an early proposal for the overall Oak component structure:</p>
+
+<p><code><a href="http://people.apache.org/~jukka/2012/oak-components-medium.png" class="external-link" rel="nofollow">http://people.apache.org/~jukka/2012/oak-components-medium.png</a></code></p>
+
+<p>A suggested way of dividing this to actual components (already outdated):</p>

+<p><code><a href="http://people.apache.org/~jukka/2012/oak-components2-medium.png" class="external-link" rel="nofollow">http://people.apache.org/~jukka/2012/oak-components2-medium.png</a></code></p>
+
+<p>Whiteboard from a discussion about how the functionality between the JCR and MP APIs should be organized:</p>
+
+<p><code><a href="http://people.apache.org/~jukka/2012/oak-components3-medium.jpg" class="external-link" rel="nofollow">http://people.apache.org/~jukka/2012/oak-components3-medium.jpg</a></code></p>
+
+<p>Functionality which goes into oak-jcr:</p>
+<ul>
+ <li>Transient space: using Microkernel for write ahead</li>
+ <li>Name space (re-) mapping: use prefix throughout the stack. Either rename or double dispatch on remapping</li>
+ <li>copy, move, import, export</li>
+ <li>UUID resolution
+<br class="atl-forced-newline"/></li>
+</ul>
+
+
+<p>Functionality which goes below the Oak API:</p>
+<ul>
+ <li>Tree update and access</li>
+ <li>Versioning (including mechanism for import)</li>
+ <li>ACL evaluation</li>
+ <li>Authentication</li>
+ <li>Name space map (i.e. the realisation of the map, not the process of (re-) mapping)</li>
+ <li>Name and path validation</li>
+ <li>Locking?</li>
+ <li>UUID map</li>
+ <li>UUID validation</li>

+
+<h3 id="OakathonAugust2017-Currentsituation">Current situation</h3>
+<p>Current segment store related tools are implemented ad-hoc by potentially relying on internal implementation details of Oak Segment Tar. This makes those tools less useful, portable, stable and potentially applicable than they should be.</p>
+
+<h3 id="OakathonAugust2017-Goal">Goal</h3>
+<p>Provide a common and sufficiently stable Oak Tooling API for implementing segment store related tools. The API should be independent of Oak and not available for normal production use of Oak. Specifically it should not be possible to it to implement production features and production features must not rely on it. It must be possible to implement the Oak Tooling API in Oak 1.8 and it should be possible for Oak 1.6.</p>
+
+<h3 id="OakathonAugust2017-Typicalusecases">Typical use cases</h3>
+<ul>
+ <li>Query the number of nodes / properties / values in a given path satisfying some criteria</li>
+ <li>Aggregate a certain value on queries like the above</li>
+ <li>Calculate size of the content / size on disk</li>
+ <li>Analyse changes. E.g. how many binaries bigger than a certain threshold were added / removed between two given revisions. What is the sum of their sizes?</li>
+ <li>Analyse locality: measure of locality of node states.

+
+<p>A metrics reporter using RRD4J has been implemented in Apache Sling (<a href="https://issues.apache.org/jira/browse/SLING-7055" class="external-link" rel="nofollow">SLING-7055</a>). It writes metrics periodically into a time-series database on the local file system.</p>
+
+<h3 id="OakathonAugust2017-Openquestions">Open questions</h3>
+<ul>
+ <li>How expensive is it to gather metrics? What if reading a metric is too expensive because the custom metric implementation is troublesome? Should the reporter detect and blacklist such metrics? Alternatively, the reporter could automatically increase the interval for reading such metrics.</li>
+ <li>It would be useful to also have RRD archives with MAXIMUM consolidation function. E.g. for tracking the observation queue length.</li>
+ <li>How should timer and histogram metrics be written to RRD? Those are not simple values, but expose already aggregated data.

+
+<h3 id="OakathonAugust2017-Moremetrics">More metrics</h3>
+<p>It may be useful to have more metrics OOTB in Oak.</p>
