Creating custom CacheLoader

moia Oct 26, 2012 11:07 AM

I need to create a CacheLoader which reads from our relational database structure. I cannot use the provided cache loader implementations, as our structure is specific, and a lot of data manipulation (including reading from multiple tables) will happen there.

I overriden AbstractCacheLoader and AbstractCacheLoaderConfig classes (the latter to be able to get db connection). But it seems, that my cacheloader specific configuration which I provide in <properties> section is not applied to my cacheloader.

I found that LegacyConfigurationAdaptor applies these properties only if the CacheLoaderConfig is instanceof AbstractCacheStoreConfig - this seems strange, as I don't want to implement CacheStore, only CacheLoader interface. Is there any way to apply these properties to my cacheloader?

Another question is if there is any simpler way to provide cacheloaders (and cachestores)? I mean injecting some spring beans, or something in this fashion?

Best regards,

Mikolaj

The CacheLoader/Store SPI is over-complex and in need of a rearchitecture which won't happen before 6.0. For an example of a relatively simple Store, look at the DummyInMemoryCacheStore (core/src/test/java/org/infinispan/loaders/dummy/)

Agree . Probabaly a simpler approach for cache preload ( Lots of questions on cache preload in different forums ) from RDBMS will help .
