在Spring Boot中使用Apache Ignite创建缓存表进行持久化,需要进行如下配置:
1. 在Spring Boot的配置文件中,配置Ignite的持久化存储路径:
```
# Ignite persistence settings.
ignite.configuration.dataStorageConfiguration.storagePath = /path/to/persistence/store
```
2. 在Spring Boot的配置文件中,配置Ignite缓存表相关属性,包括缓存模式、持久化等:
```
# Ignite cache configuration.
ignite.cache.myCache.atomicityMode = ATOMIC
ignite.cache.myCache.cacheMode = PARTITIONED
ignite.cache.myCache.backups = 1
ignite.cache.myCache.writeBehindEnabled = true
ignite.cache.myCache.writeBehindFlushSize = 10240
ignite.cache.myCache.writeBehindFlushFrequency = 5000
ignite.cache.myCache.writeBehindBatchSize = 512
ignite.cache.myCache.evictionPolicy.factory = org.apache.ignite.cache.eviction.lru.LruEvictionPolicyFactory
ignite.cache.myCache.evictionPolicy.factory.maxSize = 100000
ignite.cache.myCache.onheapCacheEnabled = true
ignite.cache.myCache.persistenceEnabled = true
```
其中,writeBehindEnabled开启了写后处理,writeBehindFlushSize设置了写后处理的缓存大小,writeBehindFlushFrequency设置了写后处理的刷新频率,writeBehindBatchSize设置了写后处理的批量大小。这些参数可以根据实际情况进行调整。
3. 在Spring Boot的配置文件中,配置Ignite的缓存表名称和数据类型:
```
# Ignite cache configuration.
ignite.cache.myCache.name = myCache
ignite.cache.myCache.cacheStoreFactory = org.apache.ignite.cache.store.jdbc.CacheJdbcPojoStoreFactory
ignite.cache.myCache.cacheStoreFactory.dataSourceBean = javax.sql.DataSource#myDataSource
ignite.cache.myCache.cacheStoreFactory.dialect = org.apache.ignite.cache.store.jdbc.dialect.MySQLDialect
ignite.cache.myCache.cacheStoreFactory.persistenceSettings = org.apache.ignite.cache.store.jdbc.JdbcTypeField[]
ignite.cache.myCache.cacheStoreFactory.writeThrough = true
ignite.cache.myCache.cacheStoreFactory.writeBehindEnabled = true
ignite.cache.myCache.cacheStoreFactory.writeBehindBatchSize = 512
ignite.cache.myCache.cacheStoreFactory.writeBehindFlushFrequency = 5000
ignite.cache.myCache.cacheStoreFactory.writeBehindFlushSize = 10240
ignite.cache.myCache.cacheStoreFactory.maximumSize = 100000
ignite.cache.myCache.cacheStoreFactory.maximumWriteAttempts = 10
ignite.cache.myCache.cacheStoreFactory.parallelLoadCacheMinimumThreshold = 100
ignite.cache.myCache.cacheStoreFactory.primaryKeyFields = id
ignite.cache.myCache.cacheStoreFactory.valueType = com.example.model.Person
```
其中,cacheStoreFactory指定了缓存表的数据源、数据库方言、持久化设置等信息,valueType指定了缓存表的数据类型。
通过以上配置,就可以在Spring Boot中使用Apache Ignite创建缓存表进行持久化。当缓存中的数据发生变化时,数据会被写入到磁盘中,从而保证数据的持久化。
