+# Apache Ignite Examples
+
+This module contains examples of how to run [Apache Ignite](ignite.apache.org) and [Apache Ignite](ignite.apache.org) with 3rd party components.
+
+Instructions on how to start examples can be found in [README.txt](README.txt).
+
+## Running examples on JDK 9/10/11
+
+Ignite uses proprietary SDK APIs that are not available by default. See also [How to run Ignite on JDK 9,10 and 11](https://ignite.apache.org/docs/latest/setup#running-ignite-with-java-11-or-later)
+
+To set up local IDE to easier access to examples, it is possible to add following options as default for all applications
+
+``--add-exports=java.base/jdk.internal.misc=ALL-UNNAMED
+ --add-exports=java.base/sun.nio.ch=ALL-UNNAMED
+ --add-exports=java.management/com.sun.jmx.mbeanserver=ALL-UNNAMED
+ --add-exports=jdk.internal.jvmstat/sun.jvmstat.monitor=ALL-UNNAMED
+ --add-exports=java.base/sun.reflect.generics.reflectiveObjects=ALL-UNNAMED
+ --add-opens=jdk.management/com.sun.management.internal=ALL-UNNAMED
+ --illegal-access=permit``
+
+For example, for IntelliJ IDEA it is possible to use Application Templates.
+
+Use 'Run' -> 'Edit Configuration' menu.
+
+<img src="https://docs.google.com/drawings/d/e/2PACX-1vQFgjhrPsLPUmic8CA_s1YpjVwA2vQITxNsLrAKOecZxIQEZSb1Ps2XKh0QEn8z9vtYiUofnGek_cag/pub?w=960&h=720"/>
+
+## Contributing to Examples
+
+*Notice* When updating classpath of examples and in case any modifications required in [pom.xml](pom.xml)
+please make sure that corresponding changes were applied to
+ * [pom-standalone.xml](pom-standalone.xml),
+ * [pom-standalone-lgpl.xml](pom-standalone-lgpl.xml).
+
+ These pom files are finalized during release and placed to the `examples` folder with these examples code.

+Apache Ignite Examples
+======================
+
+Examples are shipped as a separate Maven project, so to start running you simply need
+to import provided `pom.xml` file into your favourite IDE.
+
+
+Starting Remote Nodes
+=====================
+
+Remote nodes for examples should always be started with special configuration file which enables P2P
+class loading: `examples/config/example-ignite.xml`. To run a remote node in IDE use `ExampleNodeStartup` class.
+
+
+LGPL
+=====
+It is required some lgpl-based libs, for example: ignite-hibernate or ignite-schedule.
+In case these libs can not be found by this maven project please download Apache Ignite sources
+at https://ignite.apache.org/download.cgi#sources.
+
+There is a way to gain required libs from sources:
+
+Run "./mvnw clean install -DskipTests " at Apache Ignite sources.
+This case will install lgpl-based libs to local maven repository.
+
+Required libs will also appear at /target/release-package/libs/optional sub-folders.
+Found libs should be copied to global or project's classpath.

+/**
+ * This example demonstrates the use of Ignite In-Memory Data Ignite cluster as a Hibernate
+ * Second-Level cache provider.
+ * <p>
+ * The Hibernate Second-Level cache (or "L2 cache" shortly) lets you significantly
+ * reduce the number of requests to the underlying SQL database. Because database
+ * access is known to be an expansive operation, using L2 cache may improve
+ * performance dramatically.
+ * <p>
+ * This example defines 2 entity classes: {@link User} and {@link Post}, with
+ * 1 <-> N relation, and marks them with appropriate annotations for Hibernate
+ * object-relational mapping to SQL tables of an underlying H2 in-memory database.
+ * The example launches node in the same JVM and registers it in
+ * Hibernate configuration as an L2 cache implementation. It then stores and
+ * queries instances of the entity classes to and from the database, having
+ * Hibernate SQL output, L2 cache statistics output, and Ignite cache metrics
+ * output enabled.
+ * <p>
+ * When running example, it's easy to notice that when an object is first
+ * put into a database, the L2 cache is not used and it's contents is empty.
+ * However, when an object is first read from the database, it is immediately
+ * stored in L2 cache (which is Ignite In-Memory Data Ignite cluster in fact), which can
+ * be seen in stats output. Further requests of the same object only read the data
+ * from L2 cache and do not hit the database.
+ * <p>
+ * In this example, the Hibernate query cache is also enabled. Query cache lets you
+ * avoid hitting the database in case of repetitive queries with the same parameter
+ * values. You may notice that when the example runs the same query repeatedly in
+ * loop, only the first query hits the database and the successive requests take the
+ * data from L2 cache.
+ * <p>
+ * Note: this example uses {@link AccessType#READ_ONLY} L2 cache access type, but you
+ * can experiment with other access types by modifying the Hibernate configuration file
+ * {@code IGNITE_HOME/examples/config/hibernate/example-hibernate-L2-cache.xml}, used by the example.
+ * <p>
+ * Remote nodes should always be started with special configuration file which
+ * enables P2P class loading: {@code 'ignite.{sh|bat} examples/config/example-ignite.xml'}.
+ * <p>
+ * Alternatively you can run {@link ExampleNodeStartup} in another JVM which will
+ * start node with {@code examples/config/example-ignite.xml} configuration.

+Apache Ignite Hibernate Module
+------------------------------
+
+Apache Ignite Hibernate module provides Hibernate second-level cache (L2 cache) implementation based
+on Apache Ignite In-Memory Data Grid.
+
+To enable Hibernate module when starting a standalone node, move 'optional/ignite-hibernate' folder to
+'libs' folder before running 'ignite.{sh|bat}' script. The content of the module folder will
+be added to classpath in this case.
+
+Importing Hibernate Module In Maven Project
+-------------------------------------------
+
+If you are using Maven to manage dependencies of your project, you can add Hibernate module
+dependency like this (replace '${ignite.version}' with actual Ignite version you are
+interested in):
+
+<project xmlns="http://maven.apache.org/POM/4.0.0"
+ xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
+ xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
+ http://maven.apache.org/xsd/maven-4.0.0.xsd">
+ ...
+ <dependencies>
+ ...
+ <dependency>
+ <groupId>org.apache.ignite</groupId>
+ <artifactId>ignite-hibernate-ext</artifactId>
+ <version>${ignite.version}</version>
+ </dependency>
+ ...
+ </dependencies>
+ ...
+</project>
+
+
+LGPL dependencies
+-----------------
+
+Ignite includes the following optional LGPL dependencies:
+ - Hibernate L2 Cache Integration, http://hibernate.org/orm/
+ - JTS Topology Suite for Geospatial indexing, http://tsusiatsoftware.net/jts/main.html
+ - cron4j for cron-based task scheduling, http://www.sauronsoftware.it/projects/cron4j
+
+Apache binary releases cannot include LGPL dependencies. If you would like include
+optional LGPL dependencies into your release, you should download the source release
+from Ignite website and do the build with the following maven command:
+
+./mvnw clean package -DskipTests

+ * at the start of the session and closed when it ends.

+ * {@link CacheHibernateStoreSessionListener} requires that either
+ * {@link #setSessionFactory(SessionFactory)} session factory}
