Subject read through not work
Date Thu, 19 May 2016 12:35:12 GMT
Hi  there,
I am trying to load a data record via read through method from cache.
My cache configuration set read through to true, my cache key is an object with 5 fields,
2 of them might be null.
When I called the following functions :
IgniteCache<MetaUniqueIndexKey, BinaryObject> binaryCache = cache.withKeepBinary();
BinaryObject v1 = binaryCache.get(key1);
I got null, (the cache is empty, however the record is ready in the database, it does not
automatically load into cache).

When I check the log file, I notice that there is no error message, only one warning. The
log message contains the following information:
[20:00:05,476][INFO][main][GridDiscoveryManager] Topology snapshot [ver=277, servers=3, clients=0,
CPUs=20, heap=20.0GB]
[20:00:11,388][WARNING][main][GridDhtColocatedCache] <com.huawei.soa.ignite.model.IgniteMetaUniqueField_Cache>
For best performance you should implement java.io.Externalizable for all cache keys and values:
com.huawei.soa.ignite.model.MetaUniqueIndexKey
[20:00:11,711][INFO][main][GridTcpRestProtocol] Command protocol successfully stopped: TCP
binary
[20:00:11,796][INFO][main][GridCacheProcessor] Stopped cache: null
[20:00:11,797][INFO][main][GridCacheProcessor] Stopped cache: ignite-marshaller-sys-cache
[20:00:11,797][INFO][main][GridCacheProcessor] Stopped cache: ignite-sys-cache
[20:00:11,797][INFO][main][GridCacheProcessor] Stopped cache: ignite-atomics-sys-cache


Anyone know what's wrong here?


Many thanks,
Kevin
