<p>Airflow was built to interact with its metadata using <a class="reference external" href="https://docs.sqlalchemy.org/en/13/">SqlAlchemy</a>.</p>
<p>The document below describes the database engine configurations, the necessary changes to their configuration to be used with Airflow, as well as changes to the Airflow configurations to connect to these databases.</p>
<div class="section" id="choosing-database-backend">
<h2>Choosing database backend<a class="headerlink" href="#choosing-database-backend" title="Permalink to this headline"></a></h2>
<p>If you want to take a real test drive of Airflow, you should consider setting up a database backend to <strong>MySQL</strong> and <strong>PostgresSQL</strong>.
By default, Airflow uses <strong>SQLite</strong>, which is intended for development purposes only.</p>
<p>Airflow supports the following database engine versions, so make sure which version you have. Old versions may not support all SQL statements.</p>
<blockquote>
<div><ul class="simple">
<li><p>PostgreSQL: 9.6, 10, 11, 12, 13</p></li>
<li><p>MySQL: 5.7, 8</p></li>
<li><p>SQLite: 3.15.0+</p></li>
</ul>
</div></blockquote>
<p>If you plan on running more than one scheduler, you have to meet additional requirements.
For details, see <a class="reference internal" href="../concepts/scheduler.html#scheduler-ha-db-requirements"><span class="std std-ref">Scheduler HA Database Requirements</span></a>.</p>
</div>
<div class="section" id="database-uri">
<h2>Database URI<a class="headerlink" href="#database-uri" title="Permalink to this headline"></a></h2>
<p>Airflow uses SQLAlchemy to connect to the database, which requires you to configure the Database URL.
You can do this in option <code class="docutils literal notranslate"><span class="pre">sql_alchemy_conn</span></code> in section <code class="docutils literal notranslate"><span class="pre">[core]</span></code>. It is also common to configure
this option with <code class="docutils literal notranslate"><span class="pre">AIRFLOW__CORE__SQL_ALCHEMY_CONN</span></code> environment variable.</p>
<div class="admonition note">
<p class="admonition-title">Note</p>
<p>For more information on setting the configuration, see <a class="reference internal" href="set-config.html"><span class="doc">Setting Configuration Options</span></a>.</p>
</div>
<p>If you want to check the current value, you can use <code class="docutils literal notranslate"><span class="pre">airflow</span> <span class="pre">config</span> <span class="pre">get-value</span> <span class="pre">core</span> <span class="pre">sql_alchemy_conn</span></code> command as in

<div class="highlight-bash notranslate"><div class="highlight"><pre><span></span>$ airflow config get-value core sql_alchemy_conn

</pre></div>
</div>
<p>The exact format description is described in the SQLAlchemy documentation, see <a class="reference external" href="https://docs.sqlalchemy.org/en/14/core/engines.html">Database Urls</a>. We will also show you some examples below.</p>

<div class="section" id="setting-up-a-sqlite-database">
<h2>Setting up a SQLite Database<a class="headerlink" href="#setting-up-a-sqlite-database" title="Permalink to this headline"></a></h2>
<p>SQLite database can be used to run Airflow for development purpose as it does not require any database server
(the database is stored in a local file). There are a few limitations of using the SQLite database (for example
it only works with Sequential Executor) and it should NEVER be used for production.</p>
<p>There is a minimum version of sqlite3 required to run Airflow 2.0+ - minimum version is 3.15.0. Some of the
older systems have an earlier version of sqlite installed by default and for those system you need to manually
upgrade SQLite to use version newer than 3.15.0. Note, that this is not a <code class="docutils literal notranslate"><span class="pre">python</span> <span class="pre">library</span></code> version, it’s the
SQLite system-level application that needs to be upgraded. There are different ways how SQLIte might be
installed, you can find some information about that at the <a class="reference external" href="https://www.sqlite.org/index.html">official website of SQLite</a> and in the documentation specific to distribution of your Operating
System.</p>
<p><strong>Troubleshooting</strong></p>
<p>Sometimes even if you upgrade SQLite to higher version and your local python reports higher version,
the python interpreter used by Airflow might still use the older version available in the
<code class="docutils literal notranslate"><span class="pre">LD_LIBRARY_PATH</span></code> set for the python interpreter that is used to start Airflow.</p>
<p>You can make sure which version is used by the interpreter by running this check:</p>
<div class="highlight-bash notranslate"><div class="highlight"><pre><span></span>root@b8a8e73caa2c:/opt/airflow# python
Python <span class="m">3</span>.6.12 <span class="o">(</span>default, Nov <span class="m">25</span> <span class="m">2020</span>, <span class="m">03</span>:59:00<span class="o">)</span>
<span class="o">[</span>GCC <span class="m">8</span>.3.0<span class="o">]</span> on linux
Type <span class="s2">&quot;help&quot;</span>, <span class="s2">&quot;copyright&quot;</span>, <span class="s2">&quot;credits&quot;</span> or <span class="s2">&quot;license&quot;</span> <span class="k">for</span> more information.
&gt;&gt;&gt; import sqlite3
&gt;&gt;&gt; sqlite3.sqlite_version
<span class="s1">&#39;3.27.2&#39;</span>
&gt;&gt;&gt;
</pre></div>
</div>
<p>But be aware that setting environment variables for your Airflow deployment might change which SQLite
library is found first, so you might want to make sure that the “high-enough” version of SQLite is the only
version installed in your system.</p>
<p>An example URI for the sqlite database:</p>
<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>sqlite:////home/airflow/airflow.db
</pre></div>
</div>
<p><strong>Upgrading SQLite on AmazonLinux AMI or Container Image</strong></p>

<p>The database must use a UTF-8 character set</p>

<p>We rely on more strict ANSI SQL settings for MySQL in order to have sane defaults.
Make sure to have specified <code class="docutils literal notranslate"><span class="pre">explicit_defaults_for_timestamp=1</span></code> option under <code class="docutils literal notranslate"><span class="pre">[mysqld]</span></code> section
in your <code class="docutils literal notranslate"><span class="pre">my.cnf</span></code> file. You can also activate these options with the <code class="docutils literal notranslate"><span class="pre">--explicit-defaults-for-timestamp</span></code> switch passed to <code class="docutils literal notranslate"><span class="pre">mysqld</span></code> executable</p>
<p>We recommend using the <code class="docutils literal notranslate"><span class="pre">mysqlclient</span></code> driver and specifying it in your SqlAlchemy connection string.</p>
<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>mysql+mysqldb://&lt;user&gt;:&lt;password&gt;@&lt;host&gt;[:&lt;port&gt;]/&lt;dbname&gt;
</pre></div>
</div>
<p>But we also support the <code class="docutils literal notranslate"><span class="pre">mysql-connector-python</span></code> driver, which lets you connect through SSL
without any cert options provided.</p>
<div class="highlight-text notranslate"><div class="highlight"><pre><span></span>mysql+mysqlconnector://&lt;user&gt;:&lt;password&gt;@&lt;host&gt;[:&lt;port&gt;]/&lt;dbname&gt;
</pre></div>
</div>
<p>However if you want to use other drivers visit the <a class="reference external" href="https://docs.sqlalchemy.org/en/13/dialects/mysql.html">MySQL Dialect</a> in SQLAlchemy documentation for more information regarding download
and setup of the SqlAlchemy connection.</p>
<p>In addition, you also should pay particular attention to MySQL’s encoding. Although the <code class="docutils literal notranslate"><span class="pre">utf8mb4</span></code> character set is more and more popular for MySQL (actually, <code class="docutils literal notranslate"><span class="pre">utf8mb4</span></code> becomes default character set in MySQL8.0), using the <code class="docutils literal notranslate"><span class="pre">utf8mb4</span></code> encoding requires additional setting in Airflow 2+ (See more details in <a class="reference external" href="https://github.com/apache/airflow/pull/7570">#7570</a>.). If you use <code class="docutils literal notranslate"><span class="pre">utf8mb4</span></code> as character set, you should also set <code class="docutils literal notranslate"><span class="pre">sql_engine_collation_for_ids=utf8mb3_general_ci</span></code>.</p>

</div>
<p>Also note that since SqlAlchemy does not expose a way to target a specific schema in the database URI, you may
want to set a default schema for your role with a SQL statement similar to <code class="docutils literal notranslate"><span class="pre">ALTER</span> <span class="pre">ROLE</span> <span class="pre">username</span> <span class="pre">SET</span> <span class="pre">search_path</span> <span class="pre">=</span> <span class="pre">airflow,</span> <span class="pre">foobar;</span></code></p>

<div class="admonition note">
<p class="admonition-title">Note</p>
<p>Airflow is known - especially in high-performance setup - to open many connections to metadata database. This might cause problems for
Postgres resource usage, because in Postgres, each connection creates a new process and it makes Postgres resource-hungry when a lot
of connections are opened. Therefore we recommend to use <a class="reference external" href="https://www.pgbouncer.org/">PGBouncer</a> as database proxy for all Postgres
production installations. PGBouncer can handle connection pooling from multiple components, but also in case you have remote
database with potentially unstable connectivity, it will make your DB connectivity much more resilient to temporary network problems.
Example implementation of PGBouncer deployment can be found in the <a class="reference external" href="/docs/helm-chart/latest/index.html" title="(in helm-chart v1.2.0-rc1)"><span>Helm Chart for Apache Airflow</span></a> where you can enable pre-configured
PGBouncer instance with flipping a boolean flag. You can take a look at the approach we have taken there and use it as
an inspiration, when you prepare your own Deployment, even if you do not use the Official Helm Chart.</p>
<p>See also <a class="reference external" href="/docs/helm-chart/latest/production-guide.html#production-guide-pgbouncer" title="(in helm-chart v1.2.0-rc1)"><span class="xref std std-ref">Helm Chart production guide</span></a></p>
