+<p>Ignite binary client protocol enables user applications to communicate with an existing Ignite cluster without starting a full-fledged Ignite node.
+An application can connect to the cluster through a raw TCP socket. Once the connection is established, the application can communicate with the Ignite cluster and perform cache operations using the established format.</p>
+</div>
+<div class="paragraph">
+<p>This Alpha release implementation of binary client protocol comes with the following improvements:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p>Implemented <a href="https://cwiki.apache.org/confluence/display/IGNITE/IEP-75+Thin+Client+MsgPack+Serialization" target="_blank" rel="noopener">MsgPack</a> as an underlying binary format;</p>
+</li>
+<li>
+<p>Added new set of data types;</p>
+</li>
+<li>
+<p>Added more flexible and extensible handshake with the magic header string.</p>
+</li>
+</ul>
+</div>
+<div class="paragraph">

+<p>Ignite Persistence, or Native Persistence, is a set of features designed to provide persistent storage.
+When it is enabled, Ignite always stores all the data on disk, and loads as much data as it can into RAM for processing.
+For example, if there are 100 entries and RAM has the capacity to store only 20, then all 100 are stored on disk and only 20 are cached in RAM for better performance.</p>
+</div>
+<div class="paragraph">
+<p>When Native persistence is turned off and no external storage is used, Ignite behaves as a pure in-memory store.</p>

+<div class="paragraph">
+<p>When a new node joins the cluster, some of the partitions are relocated to the new node so that the data remains distributed equally in the cluster. This process is called data rebalancing.
+If an existing node permanently leaves the cluster and backups are not configured, you lose the partitions stored on this node. When backups are configured, one of the backup copies of the lost partitions becomes a primary partition and the rebalancing process is initiated.</p>
+</div>
+<div class="paragraph">
+<p>WARNING:</p>
+</div>
+<div class="listingblock">
+<div class="content">
+<pre>Data rebalancing is triggered by changes in the Baseline Topology. In pure in-memory clusters, the default behavior is to start rebalancing immediately when a node leaves or joins the cluster (the baseline topology changes automatically). In clusters with persistence, the baseline topology has to be changed manually (default behavior), or can be changed automatically when automatic baseline adjustment is enabled.</pre>

+<div class="paragraph">
+<p>This Alpha release introduces new SQL engine based on the Apache Calcite framework to parse and optimize queries and generate execution plans. Previously, it was based on H2 Database.</p>
+</div>
+<div class="paragraph">
+<p>Apache Calcite is a dynamic data management framework, which mainly serves for mediating between applications and one or more data storage locations and data processing engines.
+For more information on Apache Calcite, please see the <a href="https://calcite.apache.org/docs/" target="_blank" rel="noopener">product documentation</a>.</p>
+</div>
+<div class="paragraph">
+<p>Replacing H2 SQL engine with Apache Calcite incorporates the following general improvements:</p>
+</div>
+<div class="ulist">
+<ul>
+<li>
+<p><strong>Wider SQL support</strong>: Apache Calcite, unlike H2, is specifically designed for SQL enablement on top of an arbitrary external data storage;</p>
+</li>
+<li>
+<p><strong>Better optimization algorithms</strong>: Apache Calcite optimizes queries by repeatedly applying planner rules to a relational expression;</p>
+</li>
+<li>
+<p><strong>Higher overall performance</strong>: Calcite offers much higher levels of execution flexibility, as well as higher efficiency in terms of both memory and CPU consumption.</p>
