Hi,
I'm running the CacheAPIExample below with no on-heap caching, locally
using Intellij.
The stack frame shows that the entry I put is written on heap (using
BinaryOnheapOutputStream) and not off-heap (using BinaryOffheapOutputStream).
What's going on?
try (Ignite ignite =
Ignition.start("examples/config/example-ignite.xml")) {
System.out.println();
System.out.println(">>> Cache API example started.");
CacheConfiguration cfg = new
CacheConfiguration<>();
cfg.setOnheapCacheEnabled(false);
cfg.setCacheMode(CacheMode.PARTITIONED);
cfg.setName(CACHE_NAME);
// Auto-close cache at the end of the example.
try (IgniteCache cache =
ignite.getOrCreateCache(cfg)) {
// Demonstrate atomic map operations.
cache.put(999, "777");
}
finally {
// Distributed cache could be removed from cluster only by
#destroyCache() call.
ignite.destroyCache(CACHE_NAME);
}
}
