<h2 id="table">Table</h2>
<p>Tables are a key concept for transparent data sharding. Apache ShardingSphere adapts to the data sharding requirements under different scenarios by providing diverse table types.</p>
<h3 id="logic-table">Logic Table</h3>
<p>The logical name of the horizontally sharded database (table) of the same structure is the logical identifier of the table in SQL. Example: Order data is split into 10 tables according to the primary key endings, are <code>t_order_0</code> to <code>t_order_9</code>, and their logical table names are <code>t_order</code>.</p>
<h3 id="actual-table">Actual Table</h3>
<p>Physical tables that exist in the horizontally sharded databases. Those are, <code>t_order_0</code> to <code>t_order_9</code> in the previous example.</p>
<h3 id="binding-table">Binding Table</h3>
<p>Refers to a set of sharded tables with consistent sharding rules. When using binding tables for multi-table associated query, a sharding key must be used for the association, otherwise, Cartesian product association or cross-library association will occur, affecting query efficiency.</p>
<p>For example, if the <code>t_order</code> table and <code>t_order_item</code> table are both sharded according to <code>order_id</code> and are correlated using <code>order_id</code>, the two tables are binding tables. The multi-table associated queries between binding tables will not have a Cartesian product association, so the associated queries will be much more effective. Here is an example,</p>
<p>If SQL is:</p>

</code></pre></div><p>In the case where no binding table relationships are being set, assume that the sharding key <code>order_id</code> routes the value 10 to slice 0 and the value 11 to slice 1, then the routed SQL should be 4 items, which are presented as a Cartesian product:</p>

<h3 id="broadcast-data-frame">Broadcast data frame</h3>
<p>Refers to tables that exist in all sharded data sources. The table structure and its data are identical in each database. Suitable for scenarios where the data volume is small and queries are required to be associated with tables of massive data, e.g., dictionary tables.</p>
<h3 id="single-table">Single Table</h3>

<h2 id="data-nodes">Data Nodes</h2>
<p>The smallest unit of the data shard, consists of the data source name and the real table. Example: <code>ds_0.t_order_0</code>.</p>

</code></pre></div><h2 id="sharding">Sharding</h2>
<h3 id="sharding-key">Sharding key</h3>
<p>A database field is used to split a database (table) horizontally. Example: If the order primary key in the order table is sharded by modulo, the order primary key is a sharded field. If there is no sharded field in SQL, full routing will be executed, of which performance is poor. In addition to the support for single-sharding fields, Apache ShardingSphere also supports sharding based on multiple fields.</p>
<h3 id="sharding-algorithm">Sharding Algorithm</h3>
<p>Algorithm for sharding data, supporting <code>=</code>, <code>&gt;=</code>, <code>&lt;=</code>, <code>&gt;</code>, <code>&lt;</code>, <code>BETWEEN</code> and <code>IN</code>. The sharding algorithm can be implemented by the developers themselves or can use the Apache ShardingSphere built-in sharding algorithm, syntax sugar, which is very flexible.</p>
<h3 id="automatic-sharding-algorithm">Automatic Sharding Algorithm</h3>
<p>Sharding algorithm—syntactic sugar is for conveniently hosting all data nodes without users having to concern themselves with the physical distribution of actual tables. Includes implementations of common sharding algorithms such as modulo, hash, range, and time.</p>
<h3 id="customized-sharding-algorithm">Customized Sharding Algorithm</h3>
<p>Provides a portal for application developers to implement their sharding algorithms that are closely related to their business operations, while allowing users to manage the physical distribution of actual tables themselves. Customized sharding algorithms are further divided into:</p>
<ul>
<li>Standard Sharding Algorithm
Used to deal with scenarios where sharding is performed using a single key as the sharding key <code>=</code>, <code>IN</code>, <code>BETWEEN AND</code>, <code>&gt;</code>, <code>&lt;</code>, <code>&gt;=</code>, <code>&lt;=</code>.</li>
<li>Composite Sharding Algorithm
Used to cope with scenarios where multiple keys are used as sharding keys. The logic containing multiple sharding keys is very complicated and requires the application developers to handle it on their own.</li>
<li>Hint Sharding Algorithm
For scenarios involving Hint sharding.</li>
</ul>
<h3 id="sharding-strategy">Sharding Strategy</h3>
<p>Consisting of a sharding key and sharding algorithm, which is abstracted independently due to the independence of the sharding algorithm. What is viable for sharding operations is the sharding key + sharding algorithm, known as sharding strategy.</p>
<h3 id="mandatory-sharding-routing">Mandatory Sharding routing</h3>
<p>For the scenario where the sharded field is not determined by SQL but by other external conditions, you can use SQL Hint to inject the shard value. Example: Conduct database sharding by employee login primary key, but there is no such field in the database. SQL Hint can be used both via Java API and SQL annotation. See Mandatory Sharding Routing for details.</p>
<h3 id="row-value-expressions">Row Value Expressions</h3>
<p>Row expressions are designed to address the two main issues of configuration simplification and integration. In the cumbersome configuration rules of data sharding, the large number of repetitive configurations makes the configuration itself difficult to maintain as the number of data nodes increases. The data node configuration workload can be effectively simplified by row expressions.</p>
<p>For the common sharding algorithm, using Java code implementation does not help to manage the configuration uniformly. But by writing the sharding algorithm through line expressions, the rule configuration can be effectively stored together, which is easier to browse and store.</p>
<p>Row expressions are very intuitive, just use <code>${ expression }</code> or <code>$-&gt;{ expression }</code> in the configuration to identify the row expressions. Data nodes and sharding algorithms are currently supported. The content of row expressions uses Groovy syntax, and all operations supported by Groovy are supported by row expressions. For example:</p>
<p><code>${begin..end}</code> denotes the range interval</p>
<p><code>${[unit1, unit2, unit_x]}</code> denotes the enumeration value</p>
<p>If there are multiple <code>${ expression }</code> or <code>$-&gt;{ expression }</code> expressions in a row expression, the final result of the whole expression will be a Cartesian combination based on the result of each sub-expression.</p>
<p>e.g. The following row expression:</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-Groovy" data-lang="Groovy">$<span style="color:#f92672">{[</span><span style="color:#e6db74">&#39;online&#39;</span><span style="color:#f92672">,</span> <span style="color:#e6db74">&#39;offline&#39;</span><span style="color:#f92672">]}</span>_table$<span style="color:#f92672">{</span><span style="color:#ae81ff">1</span><span style="color:#f92672">..</span><span style="color:#ae81ff">3</span><span style="color:#f92672">}</span>
</code></pre></div><p>Finally, it can be parsed as this:</p>
<div class="highlight"><pre style="color:#f8f8f2;background-color:#272822;-moz-tab-size:4;-o-tab-size:4;tab-size:4"><code class="language-PlainText" data-lang="PlainText">online_table1, online_table2, online_table3, offline_table1, offline_table2, offline_table3
</code></pre></div><h3 id="distributed-primary-key">Distributed Primary Key</h3>
<p>In traditional database software development, automatic primary key generation is a basic requirement. Various databases provide support for this requirement, such as self-incrementing keys of MySQL, self-incrementing sequences of Oracle, etc. After data sharding, it is very tricky to generate global unique primary keys for different data nodes. Self-incrementing keys between different actual tables within the same logical table generate repetitive primary keys because they are not mutually aware. Although collisions can be avoided by constraining the initial value and step size of self-incrementing primary keys, additional operational and maintenance rules are necessary to be introduced, rendering the solution lacking in completeness and scalability.</p>
<p>Many third-party solutions can perfectly solve this problem, such as UUID, which relies on specific algorithms to self-generate non-repeating keys, or by introducing primary key generation services. To facilitate users and meet their demands for different scenarios, Apache ShardingSphere not only provides built-in distributed primary key generators, such as UUID and SNOWFLAKE but also abstracts the interface of distributed primary key generators to enable users to implement their own customized self-extending primary key generators.</p>
