Here are the configurations
DataRegionConfiguration =
(new DataRegionConfiguration)
.setName("RefData")
.setInitialSize(21 * 1024 * 1024)
.setMaxSize(21 * 1024 * 1024)
.setPersistenceEnabled(false)
.setPageEvictionMode(DataPageEvictionMode.RANDOM_LRU)
.setMetricsEnabled(true)
.setEvictionThreshold(.9)
I then created a cache that uses that data region.
val cfg = new CacheConfiguration[Int, String]
cfg.setName("testCache")
.setCacheMode(CacheMode.PARTITIONED)
.setAtomicityMode(CacheAtomicityMode.ATOMIC)
.setExpiryPolicyFactory(CreatedExpiryPolicy.factoryOf(Durati
on.ETERNAL))
// .setIndexedTypes(keytag.runtimeClass, valtag.runtimeClass) uncommenting
this causes the error
.setDataRegionName("RefData"))
.setStatisticsEnabled(true)
val cacheFactory = FactoryBuilder.factoryOf("CacheConstantString")
cfg.setCacheStoreFactory(cacheFactory)
.setReadThrough(readThrough)
val myCache = ignite.getOrCreateCache(cfg)
// This is my stubbed read through
class CacheConstantString[K,V] extends CacheStoreAdapter[K, V] with
Logging {
override def load(key: K): V = {
"foo".asInstanceOf[V]
}
}
It is the combination of both cache enabled and setting indexed types that
is the problem, it works fine without either, but I need the read through.
I never see any value in the metrics except evicts=0 and I know it must be
evicting pages because i am writing 35,000 keys into a data region that
only has enough space for 8000 or so. This is a cache metric, is it
showing page evicts or key evicts? Because I have an expiry of Eternal,
so I dont expect to see key evicts
