+ <h2 id="streaming-and-operational-data">Streaming and operational
data</h2>
+
+<p>Apache Druid (incubating) generally works well with any event-oriented,
clickstream, timeseries, or telemetry data, especially streaming datasets from
<a href="https://kafka.apache.org/";>Apache Kafka</a>.
+Druid provides <a
href="http://druid.io/docs/latest/development/extensions-core/kafka-ingestion";>exactly
once consumption semantics</a> from Apache Kafka and is commonly used as a
sink for event-oriented Kafka topics.</p>
+
+<p>Druid also works well for batch data sets.
+Organizations have deployed Druid to accelerate queries and power applications
where the input data is one or more static files.
+Druid is a great fit if you are developing a user-facing application and you
want your users to be able to self service their own questions.</p>
+
+<p>Some common high level use cases of Druid include:</p>
+
+<div class="features">
+ <div class="feature">
+ <span class="fa fa-rocket fa"></span>
+ <h5>Analyze performance</h5>
+ <p>
+ Create interactive dashboards with full drill down capabilities. 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>
