13.5.2. LevelDB Cache Store Programmatic Configuration

Procedure 13.6. LevelDB Cache Store programmatic configuration

1. Create a New Configuration Builder

   Use the ConfigurationBuilder to create a new configuration object.

   Configuration cacheConfig = new ConfigurationBuilder().persistence()
   

2. Add the LevelDBStoreConfigurationBuilder Store

   Add the store to the LevelDBCacheStoreConfigurationBuilder instance to build its configuration.

   Configuration cacheConfig = new ConfigurationBuilder().persistence()
                   .addStore(LevelDBStoreConfigurationBuilder.class)
   

3. Set Up Location

   Set the LevelDB Cache Store location path. The specified path stores the primary cache store data. The directory is automatically created if it does not exist.

   Configuration cacheConfig = new ConfigurationBuilder().persistence()
                   .addStore(LevelDBStoreConfigurationBuilder.class)
                   .location("/tmp/leveldb/data")
   

4. Set Up Expired Location

   Specify the location for expired data using the expiredLocation parameter for the LevelDB Store. The specified path stores expired data before it is purged. The directory is automatically created if it does not exist.

   Configuration cacheConfig = new ConfigurationBuilder().persistence()
                   .addStore(LevelDBStoreConfigurationBuilder.class)
                   .location("/tmp/leveldb/data")
                   .expiredLocation("/tmp/leveldb/expired").build();
