IGNITE 使用注意事项

Ignite 日志

日志配置教程

Ignite 默认启动于 静默模式 ，会阻止 INFO 和 DEBUG 日志的输出。可在代码中关闭 静默模式 ：

1	System.setProperty("IGNITE_QUIET", "false");

关闭后终端会打印出更详细的 log。

数据并置与关联查询

IGNITE 工具使用

visor> cache

查看 node

查看 cache

上图中的 personCache 是在代码中创建的（使用 ignite 的 setIndexedTypes ），例子在此；

SQL_PUBLIC_CITY 是通过 SQL 语句建表生成的：

1	CREATE TABLE City (id LONG PRIMARY KEY, name VARCHAR)

cache_person 也是通过 SQL 语句建表生成的：

1	CREATE TABLE Person (id LONG PRIMARY KEY, name VARCHAR) WITH "CACHE_NAME = cache_person"

详细文档点击 ignite create-table 查看。

sqlline 工具

使用教程

位置：$IGNITE_HOME/bin/sqlline.sh

ignite 支持完整的 SQL，通过 sqlline.sh 可以直接连接 ignite 数据库服务，使用方法如下：

$ sqlline.sh
sqlline version 1.3.0
sqlline>
# 连接
sqlline> !connect jdbc:ignite:thin://localhost
Enter username for jdbc:ignite:thin://localhost:
Enter password for jdbc:ignite:thin://localhost:
0: jdbc:ignite:thin://localhost>
# 随后即可输入 SQL 命令了
0: jdbc:ignite:thin://localhost> !tables

# sqlline.sh --verbose=true -u jdbc:ignite:thin://localhost 这种也可以
$ sqlline.sh --verbose=true -u jdbc:ignite:thin://localhost
issuing: !connect jdbc:ignite:thin://localhost '' '' org.apache.ignite.IgniteJdbcThinDriver
Connecting to jdbc:ignite:thin://localhost
Connected to: Apache Ignite (version 2.8.1#20200521-sha1:86422096)
Driver: Apache Ignite Thin JDBC Driver (version 2.8.1#20200521-sha1:86422096)
Autocommit status: true
Transaction isolation: TRANSACTION_REPEATABLE_READ
sqlline version 1.3.0
0: jdbc:ignite:thin://localhost>

查看 tables

0: jdbc:ignite:thin://localhost> !tables

如上图所示，在代码中创建 Cache，CacheConfiguration.setIndexedTypes(Integer.class, Person.class); 参数中的 Person.class 的类名即为生成的 TABLE_NAME（即类名会被用作表名），Cache 名即为 TABLE_SCHEM。

查询

0: jdbc:ignite:thin://localhost> select * from "personCache".PERSON;

Ignite持久化

持久化

点击查看教程

首先持久化只能在 Server 节点，因为 Client 节点不保存数据；

持久化后，数据保存在 {WORK_DIR}/db/{nodeId} ，默认为 IGNITE_HOME/work/db 下：

子目录名	描述
`{WORK_DIR}/db/{nodeId}`	该目录中包括了缓存的数据和索引
`{WORK_DIR}/db/wal/{nodeId}`	该目录中包括了WAL文件
`{WORK_DIR}/db/wal/archive/{nodeId}`	该目录中包括了WAL存档文件

举例：

如果持久化，那么数据就会保存，比如在 Client 节点做了某些操作（新建 Cache，即创建了表，表中填充了数据），那么全部节点断开后，再启动一个持久化的 Server 时，SQL 就能直接查询之前 Client 节点操作的数据；

如果不持久化，则 SQL 无法查询之前 Client 节点操作的数据；

IgniteConfiguration igniteCfg = new IgniteConfiguration();
igniteCfg.setConsistentId("DMSServerNode"); //Set Consistent ID

// 持久化
DataStorageConfiguration storageCfg = new DataStorageConfiguration();
storageCfg.getDefaultDataRegionConfiguration().setPersistenceEnabled(true);
igniteCfg.setDataStorageConfiguration(storageCfg);

Ignite ignite = Ignition.start(igniteCfg);

持久化部分 Cache 示例

点击查看教程

Server 端

配置一个 4GB 的内存区并且开启持久化

IgniteConfiguration igniteCfg = new IgniteConfiguration();

// Ignite Persistence
DataStorageConfiguration storageCfg = new DataStorageConfiguration();
// 创建数据区
DataRegionConfiguration regionCfg = new DataRegionConfiguration();
regionCfg.setName("TableCache_Region"); // 数据区名称
regionCfg.setInitialSize(100L * 1024 * 1024); // 设置初始化 RAM 大小
regionCfg.setMaxSize(4L * 1024 * 1024 * 1024); // 设置最大 RAM 大小
regionCfg.setPersistenceEnabled(true); // 开启持久化
storageCfg.setDataRegionConfigurations(regionCfg); // 设置数据区配置
igniteCfg.setDataStorageConfiguration(storageCfg); // 应用新的配置

Ignite ignite = Ignition.start(igniteCfg);

Client 端

用 Server 端配置好的区域，使得 Ignite 缓存将数据存储于其中

IgniteConfiguration igniteCfg = new IgniteConfiguration();

CacheConfiguration<Double, DMSTable> dmsTableCacheCfg = new CacheConfiguration<>();
dmsTableCacheCfg.setName("DMSTableCache");
dmsTableCacheCfg.setIndexedTypes(Double.class, DMSTable.class);
// 把 Cache 绑定到 Server 端定义好的区域中
dmsTableCacheCfg.setDataRegionName("TableCache_Region");

CacheConfiguration<Double, MasterTable> masterTableCacheCfg = new CacheConfiguration<>();
masterTableCacheCfg.setName("MasterTableCache");
masterTableCacheCfg.setIndexedTypes(Double.class, MasterTable.class);
// 把 Cache 绑定到 Server 端定义好的区域中
masterTableCacheCfg.setDataRegionName("TableCache_Region");

igniteCfg.setCacheConfiguration(dmsTableCacheCfg, masterTableCacheCfg);
igniteCfg.setClientMode(true);
Ignite ignite = Ignition.start(igniteCfg);

用这个配置启动 Ignite 集群后，固化内存会分配一个初始大小为 100MB 的内存区，然后它可以增长到 4GB，这个内存区会存储如上两个 cache 的所有数据，因为我们在 Server 端开启了持久化，所以数据的超集会一直存储于磁盘上，确保即使内存空间不足也不会出现数据丢失的情况。

如果禁用了持久化并且所有的内存使用量超过了4GB，那么会抛出内存溢出异常，要避免这个问题，可以采用如下的办法来解决：

开启Ignite的持久化存储；
启用一个可用的退出算法，注意，只有开启Ignite持久化存储时退出功能才会默认打开，否则这个功能是禁用的；
增加内存区的最大值。

配置基线拓扑

点击查看教程

如果启用了原生持久化，Ignite引入了一个 基线拓扑 的概念，它表示集群中将数据持久化到磁盘的一组服务端节点。基线拓扑是一组Ignite服务端节点，目的是同时在内存以及原生持久化中存储数据。

基线拓扑的目的是：

如果节点重启，避免不必要的数据再平衡。比如，每个节点重启都会触发两个再平衡事件，一个是节点停止，一个是节点重新加入集群，这会导致集群资源的无效利用；
集群重启后，如果基线拓扑中的所有节点都已经加入，那么集群会被自动激活。

ignite.cluster().active(true); // 激活集群

// 手动配置基线拓扑
Collection<ClusterNode> nodes = ignite.cluster().forServers().nodes();
ignite.cluster().setBaselineTopology(nodes); // 将所有服务端节点配置为基线拓扑

注意：手动配置基线拓扑的时候，必须禁用 baseline 的 auto-adjust:

1	ignite.cluster().baselineAutoAdjustEnabled(false);

上面持久化操作中，持久化后通过ignite.cluster().isBaselineAutoAdjustEnabled() 检查 auto-adjust 为 false ，此时就不再需要再用 ignite.cluster().baselineAutoAdjustEnabled(false); 禁用了。

注意： 将所有服务节点配置为基线拓扑，

禁用 Auto-just

持久化时遇到异常：

Caused by: class org.apache.ignite.spi.IgniteSpiException: Joining persistence node to in-memory cluster couldn't be allowed due to baseline auto-adjust is enabled and timeout equal to 0
    at org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi.checkFailedError(TcpDiscoverySpi.java:1997)

    at org.apache.ignite.internal.managers.GridManagerAdapter.startSpi(GridManagerAdapter.java:297)
    ... 15 more

解决方案：

启动第一个节点后，调用 ignite.cluster().baselineAutoAdjustEnabled(false) 即可，随后可用 ignite.cluster().isBaselineAutoAdjustEnabled() 检查结果。

也可使用 IGNITE_HOME/bin/control.(sh|bat) --baseline auto_adjust [disable|enable] [timeout <timeoutMillis>] [--yes] 禁用，但是我用这个方法失败，不知为何：

$ ./control.sh --baseline auto_adjust disable

2020年5月27日更新： 如果需要让集群自动调整基线拓扑，

只有当集群处于激活状态时，基线拓扑才会自动调整
此功能默认是禁用的，可以使用控制脚本开启该功能，还可以通过编程方式启用该功能
必须配置自动调整超时时间

1 2	ignite.cluster().baselineAutoAdjustEnabled(true); ignite.cluster().baselineAutoAdjustTimeout(30000);

Ignite 使用注意事项

只有 TRANSACTIONAL 原子化模式中才支持锁，分布式锁 Lock 不支持原子化模式 ATOMIC，事务原子化模式有三种（TRANSACTIONAL、TRANSACTIONAL_SNAPSHOT、ATOMIC），但是如果使用 TRANSACTIONAL_SNAPSHOT 的话，会提示 Lock 不支持 Enable MVCC ，所以要使用 TRANSACTIONAL 模式。

Caused by: class org.apache.ignite.IgniteException: Failed to start continuous query.
Caused by: java.lang.ClassNotFoundException: TOFListener

这是因为没有启动对等类加载，而终端使用 ignite.sh 启动 server 节点（remote 节点），如果不加配置文件的话，会默认加载 $IGNITE_HOME/config/default-config.xml 启动，需要在 default_config.xml 中配置对等类加载：

<bean class="org.apache.ignite.configuration.IgniteConfiguration">

    <!-- Enable peer class loading. -->
    <property name="peerClassLoadingEnabled" value="true"/>

    <!-- Set deployment mode. -->
    <property name="deploymentMode" value="CONTINUOUS"/>

</bean>

同时启动 client 节点（local 节点）的时候也需要配置对等类加载：

IgniteConfiguration cfg = new IgniteConfiguration();

cfg.setPeerClassLoadingEnabled(true);
cfg.setDeploymentMode(DeploymentMode.CONTINUOUS);

// Start a node.
Ignite ignite = Ignition.start(cfg);

注意： 因为 default-config.xml 中同时配置了 deploymentMode ，所以在启动 client 节点的时候同样要配置 deploymentMode （当然也可以都不配置），也就是说启动了对等类加载，各个节点的配置要相同，否则假如只有一端配置了对等类加载、 deploymentMode 、或者其他配置，就会报出如下 ERROR：
