Atlas?</h2> <p>By representing metadata as <strong>types</strong> and <strong>entities</strong>, Apache Atlas provides metadata management and governance capabilities for organizations to build, categorize, and govern their data assets on <a href="https://www.cloudera.com/products/open-source/apache-hadoop/apache-atlas.html">Hadoop clusters</a>.</p> <p>These “entities” are instances of <a href="https://atlan.com/what-is-metadata/">metadata</a> types that <strong>store details about metadata objects and their interlinkages.</strong></p> <p>Are you interested in Apache Atlas as a metadata management framework? Then you should get familiar with Active Metadata. Active Metadata is becoming increasingly popular because it helps data teams save time and money. Here is a basic introduction to the concept, as well as how to get started using it. <a href="https://atlan.com/resources/dataops-active-metadata-report/?ref=/what-is-apache-atlas/"><strong>Download our Free Report</strong></a> for more information.</p> <p>“<em>In Atlas, Type is the definition of metadata object, and Entity is an instance of metadata object</em>,” ~ <a href="https://developer.ibm.com/articles/apache-atlas-and-janusgraph-graph-based-meta-data-management/">IBM Developer</a></p> <p>Apache offers a state-of-the-art “atlas-modeling” service to help you outline the origins of your data, in tandem with all of its transformations and artifacts. This service takes away the hassle of managing metadata by utilizing <strong>labels</strong> and <strong>classifications</strong> to add metadata to the entities. Although anyone can create and assign labels to entities, classifications are <strong>under the control of system administrators</strong> through the action of <a href="https://atlas.apache.org/1.2.0/Atlas-Authorization-Ranger-Authorizer.html">Atlas policies</a>.</p> <p class="img-caption"><span>Atlas Labels and Classifications.

This initiative aimed to implement comprehensive data governance practices at enterprises.</p> <p>Five months later, the endeavor was <a href="https://www.academia.edu/79636326/The_Case_For_Open_Metadata">officially handed over to the Apache Foundation</a> as an open-source project, after which it continuously proved itself as a top-tier project till its graduation in mid-2017.</p> <p>Since 2015, the project has been maintained by the community for the community, and currently, <a href="https://search.maven.org/artifact/org.apache.atlas/apache-atlas/2.2.0/pom">version 2.2</a> is in operation.</p> <p class="img-caption"><span>From DGI to Apache Atlas: A Timeline.

Exerting complete control over data</h3> <p>The data charting ability that the Apache Atlas architecture provides to businesses helps both blue chips and startups to navigate their data ecosystems. It helps in mapping and organizing metadata representations, allowing you to stay attuned to your operational and analytical data usage.</p> <p><em>“Apache Atlas is designed to exchange metadata with other tools and processes within and outside of the Hadoop stack, thereby enabling platform-agnostic governance controls that effectively address compliance requirements.”<br/>~</em> <a href="https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.2/bk_data-governance/bk_data-governance.pdf"><em>Hortonworks Data Platform: Data Governance</em></a></p> <p class="img-caption"><span>Defining a Complex Process Evolution on Apache Atlas.

Mapping out lineage relationships via metadata</h3> <p>By assigning business metadata, Atlas promotes the genesis of entities that help you devise business vocabulary to keep track of your data assets. More importantly, <a href="https://atlan.com/automated-data-lineage/">a lineage map is generated automatically</a> once query information is received. The query itself is noted and its inputs and outputs are used to visualize how and when data transformations took place. Consequently, you can follow the changes and envisage impacts.</p> <p class="img-caption"><span>Mental Model of a Metadata Structure on Apache Atlas.

Providing metadata “bridges”</h3> <p>Atlas also enables the collection of metadata to be automated through the use of “<a href="https://cwiki.apache.org/confluence/display/ATLAS/Atlas+Bridges+and+Hooks">bridges</a>,” whereby this information could be imported from different data assets in a given source through the use of APIs.</p> <p class="img-caption"><span>Apache Atlas Providing a Metadata Bridge to the Hortonworks Data Platform.

Creating and maintaining business ontologies</h3> <p>By managing classifications and labels, Apache Atlas helps you empower your metadata. Its dashboard aids in annotating the labeled entities, thereby creating an infrastructure specific to your use case and business ontology. The classifications themselves are arranged in a hierarchy and the addition of a single term generates a report of all the entities associated with the query.</p> <p class="img-caption"><span>Apache Atlas Dashboard.

Data masking</h3> <p>Once data has been organized into an inventory, a data catalog is formed. Based on the classifications that act as the backbone of any given <a href="https://atlan.com/what-is-a-data-catalog/">data catalog</a>, Apache Atlas helps mask data access once integrated with <a href="https://ranger.apache.org/">Apache Ranger</a>. This feature is critical for securing access to operations and entity instances.</p> <p class="img-caption"><span>Creation of a Personally Identifiable Information tag for Data Masking.

These include:</p> <li><strong>Metadata sources & Integration:</strong> The categories used in Apache Kafka to organize messages, called Kafka message topics <strong>[Integration]</strong>, typically receive metadata through Atlas add-ons <strong>[Metadata Sources]</strong>.</li> <li><strong>Core:</strong> Atlas, therefore, has to read each message, which is subsequently stored in JanusGraph <strong>[Core]</strong>. In turn, JanusGraph is used to visualize the relationships between entities, and the datastore utilized in this case is HBase. A search index by the name of Solr is also employed to reap the benefit of its search functionalities.</li> <li><strong>Apps:</strong> All of these components allow Atlas to manage metadata, which is eventually used by various governance-oriented use cases <strong>[Applications]</strong>.</li> <p class="img-caption"><span>The Architecture of Apache Atlas. Source: <a href="https://atlas.apache.org/#/Architecture">Apache Atlas.</a></span></p> <h3 class="text-center">All the power of open source, with none of the hassle.</h3> <h3 class="text-center"><a class="btn btn-primary btn-md" href="https://atlan.com/demo">Ask Atlan Demo</a></h3> <h2 id="capabilities-of-apache-atlas">Capabilities of Apache Atlas</h2> <p>As a framework for metadata and governance, the Apache Atlas architecture imbues the following capabilities:</p> <li>Defining metadata via a Type and Entity system</li> <li>Storage of metadata through a Graph repository (JanusGraph)</li> <li>Apache Solr search proficiency</li> <li>Apache Kafka notification service</li> <li>Querying and populating metadata via APIs (Rest API)</li> <h3 id="1-defining-metadata-via-a-type-and-entity-system">1. Defining metadata via a Type and Entity system</h3> <p>One of the main modules of the tool is the Type System, whose action takes inspiration from <a href="https://self-learning-java-tutorial.blogspot.com/2022/06/atlas-type-system.html">how OOP (object-oriented programming) employs instances (i.e., entities) and classes (i.e., types)</a>. In the form of Apache Atlas data catalog, we obtain an easy and intuitive tool that models various “types” and then stores information about them as “entities” (instances). Such systemization allows users to address many of the challenges associated with data governance today via the classification and <a href="https://atlan.com/data-catalog-use-cases/">use of data catalogs</a>.</p> <p class="img-caption"><span>Apache Atlas Types and Entities. Source: <a href="https://community.cloudera.com/t5/Community-Articles/Customizing-Atlas-Part1-Model-governance-traceability-and/ta-p/249250">Cloudera.</a></span></p> <h3 id="2-storage-of-metadata-through-a-graph-repository-janusgraph">2. Storage of metadata through a Graph repository (JanusGraph)</h3> <p>After data is extracted by Atlas’ ingesting and export system, the information is discovered and indexed through the Graph Engine Module. Powered by the <a href="https://janusgraph.org/">open-source graph database called Janus</a>, this module enables Apache Atlas to not only highlight interlinkages between various entities in the data catalog but also locate the meta-information of entities according to information sources, which would be stored in a <a href="https://hbase.apache.org/">column-oriented database called HBase</a>. Apache Atlas can thus easily and resiliently handle a plethora of very large tables with sparse data.</p> <p class="img-caption"><span>Vertex (Types) and Edges (Relationships) in a JanusGraph. Source: <a href="https://developer.ibm.com/articles/apache-atlas-and-janusgraph-graph-based-meta-data-management/">IBM.</a></span></p> <h3 id="3-apache-solr-search-proficiency">3. Apache Solr search proficiency</h3> <p>The <a href="https://www.javatpoint.com/indexing-in-apache-solr">Solr indexing technology</a> (i.e., an indexing-oriented database) is used by Atlas to boost search proficiency as it facilitates discovering actions. With the help of three collections (i.e., full-text index, edge index and vertex index), users can search for data on the Atlas UI efficiently. It acts as <strong>a full-text search engine</strong> that is user-friendly and flexible.</p> <p class="img-caption"><span>Key Elements of the Solr Search Process. Source: <a href="https://solr.apache.org/guide/8_1/overview-of-searching-in-solr.html">Apache Solr.</a></span></p> <h3 id="4-apache-kafka-notification-service">4. Apache Kafka notification service</h3> <p>Another notable feature of the Apache Atlas architecture is how real-time data imports and exports can be integrated with various catalogs through Kafka. The Apache Kafka notification service permits messages to be pushed as a single Kafka topic, enabling integration with <a href="https://atlan.com/open-source-data-governance-tools/">other data governance tools</a> and the reading of permissions, together with <strong>real-time change notifications</strong>.</p> <p class="img-caption"><span>Kafka - A Message Queue Software on Steroids.

Querying and populating metadata via APIs (Rest API)</h3> <p>The HTTP Rest API is the primary method for integrating with Apache Atlas. In addition to the four main storage functions (i.e., creating, reading, updating, and deletion), Apache also offers <strong>advanced exploration</strong> and <strong>querying</strong> as it exposes a multitude of REST endpoints to work with <a href="https://atlas.apache.org/api/v2/index.html">types, entities, lineage, and data discovery</a>.</p> <p class="img-caption"><span>Kafka - Atlas Populating Metadata across Multiple Clusters.
