<p>This list summarizes the most important enhancements in Elasticsearch 7.14.
For the complete list, go to <a href="/guide/en/elasticsearch/reference/7.14/release-highlights.html" class="ulink" target="_top">Elasticsearch release highlights</a>.</p>
<div class="position-relative"><h4><a id="cross-cluster-eql-search"></a>Cross-cluster EQL search</h4><a class="edit_me edit_me_private" rel="nofollow" title="Editing on GitHub is available to Elastic" href="https://github.com/elastic/elasticsearch/edit/7.14/docs/reference/release-notes/highlights.asciidoc">edit</a></div>
<p>In 7.14, we added cross-cluster search support to EQL. Cross-cluster search lets
you run an EQL search across one or more remote clusters. See
<a href="/guide/en/elasticsearch/reference/7.14/eql.html#run-eql-search-across-clusters" class="ulink" target="_top">Run an EQL search across
clusters</a>.</p>
<div class="position-relative"><h4><a id="async-sql-search"></a>Async SQL search</h4><a class="edit_me edit_me_private" rel="nofollow" title="Editing on GitHub is available to Elastic" href="https://github.com/elastic/elasticsearch/edit/7.14/docs/reference/release-notes/highlights.asciidoc">edit</a></div>
<p>We’ve added support for async searches to Elasticsearch SQL. Searches across large data
sets or frozen data can take longer to return synchronous results. Async SQL
search lets you run these searches in the background instead. See
<a href="/guide/en/elasticsearch/reference/7.14/sql-async.html" class="ulink" target="_top">Run an async SQL search</a>.</p>
<div class="position-relative"><h4><a id="transform-top-metrics-support"></a>Transforms: support for top metrics</h4><a class="edit_me edit_me_private" rel="nofollow" title="Editing on GitHub is available to Elastic" href="https://github.com/elastic/elasticsearch/edit/7.14/docs/reference/release-notes/highlights.asciidoc">edit</a></div>
<p>Transforms are now able to support the
<a href="/guide/en/elasticsearch/reference/7.14/search-aggregations-metrics-top-metrics.html" class="ulink" target="_top">top metrics aggregation</a>.
This improves performance when grouping by many fields. If these fields are
descriptive and have the same cardinality (for example, customer first and last
name describe their customer_id), then using top metrics significantly reduces
the work needed to be done by aggregations. It is also a usability improvement
if configuring top or last value, which previously would have required a
scripted metric.</p>
<div class="position-relative"><h4><a id="ml-anomaly-detection-reset-job"></a>Anomaly detection: reset job API</h4><a class="edit_me edit_me_private" rel="nofollow" title="Editing on GitHub is available to Elastic" href="https://github.com/elastic/elasticsearch/edit/7.14/docs/reference/release-notes/highlights.asciidoc">edit</a></div>
<p>The <a href="/guide/en/elasticsearch/reference/7.14/ml-reset-job.html" class="ulink" target="_top">reset job API</a> makes it easier to start
anomaly detection jobs again from scratch, to put a job back to the state it was in
immediately after creation – equivalent to deleting it and recreating it, but
without the need to remember the configuration. It also simplifies support, as
users will be able to reset their job by a single click.</p>
<div class="position-relative"><h4><a id="match-only-text"></a>New <code class="literal">match_only_text</code> field type</h4><a class="edit_me edit_me_private" rel="nofollow" title="Editing on GitHub is available to Elastic" href="https://github.com/elastic/elasticsearch/edit/7.14/docs/reference/release-notes/highlights.asciidoc">edit</a></div>
<p><a href="/guide/en/elasticsearch/reference/7.14/text.html#match-only-text-field-type" class="ulink" target="_top"><code class="literal">match_only_text</code></a> is a new
space-optimized variant of <code class="literal">text</code> that disables scoring and performs slower
on queries that need positions. It is best suited for indexing log messages.</p>
<div class="position-relative"><h4><a id="composite-aggs-without-global-ordinals"></a>More memory-efficient composite aggregations</h4><a class="edit_me edit_me_private" rel="nofollow" title="Editing on GitHub is available to Elastic" href="https://github.com/elastic/elasticsearch/edit/7.14/docs/reference/release-notes/highlights.asciidoc">edit</a></div>
<p>Composite aggregations on <code class="literal">keyword</code> fields no longer use
<a href="/guide/en/elasticsearch/reference/7.14/eager-global-ordinals.html" class="ulink" target="_top">global ordinals</a>, which for high cardinality
fields could use a lot of heap memory as part of the
<a href="/guide/en/elasticsearch/reference/7.14/modules-fielddata.html" class="ulink" target="_top">field data cache</a>.</p>
<div class="position-relative"><h4><a id="new-migrate-data-tiers-routing-api"></a>New migrate to data tiers routing API</h4><a class="edit_me edit_me_private" rel="nofollow" title="Editing on GitHub is available to Elastic" href="https://github.com/elastic/elasticsearch/edit/7.14/docs/reference/release-notes/highlights.asciidoc">edit</a></div>
<p>7.14 introduces the <a href="/guide/en/elasticsearch/reference/7.14/ilm-migrate-to-data-tiers.html" class="ulink" target="_top">migrate to data tiers
routing API</a>. You can use the API to switch indices and ILM policies that use
attribute-based allocation filters to data tiers using
<a href="/guide/en/elasticsearch/reference/7.14/modules-node.html#node-roles" class="ulink" target="_top">node roles</a>. This lets ILM automatically move
data stream indices between tiers during phase transitions. Data tiers also give
you access to additional ILM features, such as partially mounted indices and the
frozen tier.</p>
<div class="position-relative"><h4><a id="new-terms-enum-api"></a>New terms enum API</h4><a class="edit_me edit_me_private" rel="nofollow" title="Editing on GitHub is available to Elastic" href="https://github.com/elastic/elasticsearch/edit/7.14/docs/reference/release-notes/highlights.asciidoc">edit</a></div>
<p>The new <a href="/guide/en/elasticsearch/reference/7.14/search-terms-enum.html" class="ulink" target="_top">terms enum API</a> lets you discover index
terms that match a partial string. You can use the API for search
auto-completion.</p>
<div class="position-relative"><h4><a id="automatic-geoip-updates"></a>Automatic database updates for the GeoIP processor</h4><a class="edit_me edit_me_private" rel="nofollow" title="Editing on GitHub is available to Elastic" href="https://github.com/elastic/elasticsearch/edit/7.14/docs/reference/release-notes/highlights.asciidoc">edit</a></div>
<p>The GeoIP processor uses Maxmind GeoLite2 databases to provide data
about the geographical location of IP addresses. This data changes frequently as IP addresses get reused.
In 7.14, we introduced a service that automatically updates these databases so their information is as accurate
as possible. The service is enabled by default, but its operation can be adjusted. See <a href="/guide/en/elasticsearch/reference/7.14/geoip-processor.html" class="ulink" target="_top">GeoIP processor</a></p>
