Re[2]: Mixing persistent and in memory cache

[Zhenya Stanilovsky]

hi Stephan, something wrong with configuration probably … it`s not expected 
issue.
*  plz attach somehow or send me ignite.log from all server nodes ? 
*  If you change second call :
IgniteCache kva = getInMemoryKeyValue(igA);
 
 IgniteCache kvb = getInMemoryKeyValue(igB); ← here
for something like : IgniteCache kvb = 
getInMemoryKeyValue2(igB);
 
private IgniteCache getInMemoryKeyValue2(Ignite ignite)
 {
 return ignite.cache(new CacheConfiguration() <--- 
 
just to check that cache has been already created.
 
Does ignite.cache will see the previously created cache ?
 
thanks !

Hi Zhenya,

your 2nd point: yes, the cache itself has been propagated.

Please be aware that I have successfully used the same test with only the 
in-memory region as well as with only the persistent region. Only when I 
combine both, the synchronization stops working for the in memory region.


Please find attached the log file (both Ignite nodes run in the same process 
and contribute to this log file) as well as the current Junit test.

In the log file you will find:

The node startup:
>>>> starting node A
>>>> starting node B

The test case startup:
 testMem2

The test stops with:
java.lang.AssertionError: expected: but was:

Hi Zhenya, thanks for this suggestion.

However, neither setting CacheWriteSynchronizationMode to Full Sync nor
setting it to FULL_ASYNC changes anything: memory cahce changes do not get
propagated:

private IgniteCache getInMemoryKeyValue(Ignite ignite)
{
return ignite.getOrCreateCache(new CacheConfiguration()
.setName("memkv")
.setCacheMode(CacheMode.REPLICATED)
.setDataRegionName(NodeController.IN_MEMORY_REGION)
.setWriteSynchronizationMode(CacheWriteSynchronizationMode.FULL_SYNC)
.setBackups(2));
}
