Please contact one of the -existing committers for a walk through the process. Basically, what we're -looking for is an interest in ongoing contributions to Druid.</p> - -<h3 id="general-committer-guidelines">General committer guidelines</h3> - -<p>If you are an official Druid committer then congratulations! You are part of a fantastic group of people. Here are some guidelines to follow to help ensure the Druid project continues to grow and improve:</p> - -<ol> -<li>You can merge your own pull request if it fits the rest of the criteria. A common thing to see is "+1 after travis" from other committers.</li> -<li>A pull request should have at least one +1 from a committer who is not the author, on the "code/textual" level of review.</li> -<li>Pull requests which have just one +1 from a committer couldn't be merged earlier than after 3 working days since PR submission.</li> -<li>A pull request with just one +1 could be merged only by (or in coordination with) the committer who provided the review. Because the reviewer may think that the PR is complex or risky enough that needs another pair of eyes to look at it. If this is the case, the first reviewer should indicate this in the PR approval message.</li> -<li>If a pull request has two or more +1's from committers who are not the author, it could be merged immediately and by any committer. But still, enough time since the PR submission should pass to give folks a reasonable chance to indicate a desire to comment on the pull request. AKA: don't merge a pull request that was submitted Friday evening until at least 1~2 regular work days have passed. Use good judgement here.</li> -<li>Major architectural and backwards incompatible changes, or changes which have long-term maintainance consequences (see examples in <a href="#getting-your-changes-accepted">the "Getting your changes accepted" section above</a>), should have at least three +1's from committers, on the "design" level of review. One approval could be from the author of the PR. The first committer who indicates that a PR needs design review should add the <code>Design Review</code> [...] -<li>Travis-CI should pass or have some <strong>very</strong> good reason why it won't pass for a pull request.</li> -<li>You reasonably believe that all comments have been addressed.</li> -<li>You are expected to be the champion for your own pull requests.</li> -<li>Being a champion on a pull request can be a significant undertaking depending on the size of the code change and what parts of the code it touches. It may require communicating with other developers, reconciling differences, organizing community feedback, and/or following up with people who have commented in a pull request to ensure comments have been addressed.</li> -<li>Sometimes code is presented as a work-in-progress or as a point of discussion. Use the <code>WIP</code> or <code>Discuss</code> tags on a pull request in such a case.</li> -<li>If a pull request you are championing is taking longer than expected to merge, be sure to raise the issue in the developer sync.</li> -<li>Limit the number of pull requests you are championing at the same time.</li> -<li>Prioritize code reviews to look at pull requests that are blockers for the next release (see the Milestone marker on the pull request)</li> -<li>Help serve as champion for pull requests that originate from new committers.</li> -<li>If you feel a pull request is required for the next release, mark it as such in the Milestone of the pull request.</li> -<li>Do not comment on a pull request unless you are willing to follow up on the edits.</li> -<li>Give priority to getting older pull requests merged. (Either as their champion or as an active commenter)</li> -<li>And most importantly.. the PMC desires to ensure a positive and effective developer experience! If you find that things are not functioning to your expectations, pleaes raise the issue.</li> -</ol> - -<p>Remember, we all want to see this project thrive!</p> - -<h2 id="governance">Governance</h2> - -<p>The PMC (Project Management Committee) is responsible for the administrative -aspects of the Druid project.

Please contact one of the +existing committers for a walk through the process. Basically, what we're +looking for is an interest in ongoing contributions to Druid. + +### General committer guidelines +If you are an official Druid committer then congratulations! You are part of a fantastic group of people. Here are some guidelines to follow to help ensure the Druid project continues to grow and improve: + +1. You can merge your own pull request if it fits the rest of the criteria. A common thing to see is "+1 after travis" from other committers. +1. A pull request should have at least one +1 from a committer who is not the author, on the "code/textual" level of review. +1. Pull requests which have just one +1 from a committer couldn't be merged earlier than after 3 working days since PR submission. +1. A pull request with just one +1 could be merged only by (or in coordination with) the committer who provided the review. Because the reviewer may think that the PR is complex or risky enough that needs another pair of eyes to look at it. If this is the case, the first reviewer should indicate this in the PR approval message. +1. If a pull request has two or more +1's from committers who are not the author, it could be merged immediately and by any committer. But still, enough time since the PR submission should pass to give folks a reasonable chance to indicate a desire to comment on the pull request. AKA: don't merge a pull request that was submitted Friday evening until at least 1~2 regular work days have passed. Use good judgement here. +1. Major architectural and backwards incompatible changes, or changes which have long-term maintainance consequences (see examples in [the "Getting your changes accepted" section above](#getting-your-changes-accepted)), should have at least three +1's from committers, on the "design" level of review. One approval could be from the author of the PR. The first committer who indicates that a PR needs design review should add the `Design Review` tag to such a pull request. +1. Travis-CI should pass or have some **very** good reason why it won't pass for a pull request. +1. You reasonably believe that all comments have been addressed. +1. You are expected to be the champion for your own pull requests. +1. Being a champion on a pull request can be a significant undertaking depending on the size of the code change and what parts of the code it touches. It may require communicating with other developers, reconciling differences, organizing community feedback, and/or following up with people who have commented in a pull request to ensure comments have been addressed. +1. Sometimes code is presented as a work-in-progress or as a point of discussion. Use the `WIP` or `Discuss` tags on a pull request in such a case. +1. If a pull request you are championing is taking longer than expected to merge, be sure to raise the issue in the developer sync. +1. Limit the number of pull requests you are championing at the same time. +1. Prioritize code reviews to look at pull requests that are blockers for the next release (see the Milestone marker on the pull request) +1. Help serve as champion for pull requests that originate from new committers. +1. If you feel a pull request is required for the next release, mark it as such in the Milestone of the pull request. +1. Do not comment on a pull request unless you are willing to follow up on the edits. +1. Give priority to getting older pull requests merged. (Either as their champion or as an active commenter) +1. And most importantly.. the PMC desires to ensure a positive and effective developer experience! If you find that things are not functioning to your expectations, pleaes raise the issue. + +Remember, we all want to see this project thrive! + +## Governance + +The PMC (Project Management Committee) is responsible for the administrative +aspects of the Druid project.

Analyze performance of digital products, track mobile app usage, or monitor site reliability. - </p> - </div> - <div class="feature"> - <span class="fa fa-exclamation-triangle fa"></span> - <h5>Diagnose problems</h5> - <p> - Find the root cause of issues. Troubleshoot netflow bottlenecks, analyze security threats, or diagnose software crashes. - </p> - </div> - <div class="feature"> - <span class="fa fa-users fa"></span> - <h5>Find commonalities</h5> - <p> - Find common attributes among events. Identify shared components in defective products, or determine patterns in top performing products. - </p> - </div> - <div class="feature"> - <span class="fa fa-money-bill-wave-alt fa"></span> - <h5>Increase efficiency</h5> - <p> - Improve product engagement. Optimize ad-spend in digital marketing campaigns or increase user engagement in online products. - </p> - </div> -</div> - -<h2 id="user-activity-and-behavior">User activity and behavior</h2> - -<p>Druid is often used for clickstreams, viewstreams, and activity streams. -Specific use cases include measuring user engagement, tracking A/B test data for product releases, and understanding usage patterns.</p> - -<p>Druid can compute user metrics such as <a href="http://druid.io/docs/latest/querying/aggregations";>distinct counts</a> both exactly and approximately. -This mean measures such as daily active users can be computed in under a second approximately (with 98% avg. accuracy) to view general trends, or computed exactly to present to key stakeholders. -Furthermore, Druid can be used for <a href="http://druid.io/docs/latest/development/extensions-core/datasketches-aggregators";>funnel analysis</a>, and to measure how many users took one action, but did not take another action. -Such analysis is useful is tracking user signups for a product.</p> - -<p>Druid’s search and filter capabilities enable rapid, easy drill-downs of users along any set of attributes. -Measure and compare user activity by age, gender, location, and much more.</p> - -<h2 id="network-flows">Network flows</h2> - -<p>Druid is commonly used to collect and analyze network flows. -Druid is used to arbitrarily slice and dice flow data along any set of attributes.</p> - -<p>Druid helps with network flow analysis by being able to ingest large amounts of flow records, and by being able to group or rank across dozens of attributes at query time at interactive speeds. -These attributes often include core attributes like IP and port, as well as attributes added through enhancement such as geolocation, service, application, facility, and ASN. -Druid's ability to handle flexible schemas means that you can add any attributes you want.</p> - -<h2 id="digital-marketing">Digital marketing</h2> - -<p>Druid is commonly used to store and query online advertising data. -This data typically comes from ad servers and is critical to measure and understand advertising campaign performance, click through rates, conversion rates (attrition rates), and much more.</p> - -<p>Druid was initially designed to power a user-facing analytics application for digital advertising data. -Druid has seen substantial production use for this type of data and the largest users in the world have petabytes of data stored on thousands of servers.</p> - -<p>Druid can be used to compute impressions, clicks, eCPM, and key conversion metrics, filtered on publisher, campaign, user information, and dozens of other dimensions supporting full slice and dice capability.</p> - -<h2 id="application-performance-management">Application performance management</h2> - -<p>Druid is often used to track the operational data generated by applications. -Similar to the user activity use case, this data can be about how users are interacting with an application or it can be the metrics emitted by the application itself. -Druid can be used to drill into how different components of an application are performing, identify bottlenecks, and troubleshoot issues.</p> - -<p>Unlike many traditional solutions, there are few limits to the volume, complexity, and throughput of the data. -Rapidly analyze application events with thousands of attributes, and compute complex metrics on load, performance, and usage. -For example, rank API endpoints based on 95th percentile query latency, and slice and dice how these metrics change based on any ad-hoc set of attributes such as time of day, user demographic, or datacenter location.</p> - -<h2 id="iot-and-device-metrics">IoT and device metrics</h2> - -<p>Druid can be used as a time series solution for server and device metrics. -Ingest machine generated data in real-time, and perform rapid ad-hoc analytics to measure performance, optimize hardware resources, or identify issues.</p> - -<p>Unlike many traditional timeseries databases, Druid is an analytics engine at heart. -Druid combines ideas of timeseries databases, column-oriented analytic databases, and search systems. -Druid supports time-based partitioning, column-oriented storage, and search indexes in a single system. -This means time-based queries, numerical aggregations, and search and filter queries are all extremely fast.</p> - -<p>You can include millions of unique dimension values with your metrics, and arbitrarily group and filter on any combination of dimensions (dimensions in Druid are similar to tags in TSDBs). -You can group and rank on tags, and compute a variety of complex metrics. -Furthermore, you search and filter on tag values orders of magnitude faster than in traditional timeseries databases.</p> - -<h2 id="olap-and-business-intelligence">OLAP and business intelligence</h2> - -<p>Druid is commonly used for BI use cases. -Organizations have deployed Druid to accelerate queries and power applications. -Unlike SQL-on-Hadoop engines such as Presto or Hive, Druid is designed for high concurrency and sub-second queries, powering interactive data exploration through a UI. -In general this makes Druid a better fit for truly interactive visual analytics.</p> - -<p>Druid is a great fit if you need a user-facing application and you want your users to be able to run their own self service drill-down queries. -You can either develop your own application using Druid's API or use one of the <a href="http://druid.io/libraries";>many off the shelf applications</a> that work with Druid.</p> -
