CacheStore and ignite.close
Hello!
I'm working on https://issues.apache.org/jira/browse/IGNITE-9093 test fix
Turns out, IgniteDbPutGetWithCacheStoreTest.testReadThrough fails
sporadically because the default ignite.close() is close(cancel=true), and
it seems that it abandons cache store operations. So not all data is
read/written from cache store.
Is it really so? Is it considered safe?
I have a pull request on this topic:
https://github.com/apache/ignite/pull/4545
Regards,

Hello!
It turns out there's some problem with checkpointing-WAL interference.
close(true) cancels current checkpoint, and upon restart some data is
missing from the cache.
We are investigating this.

Ilya,
Can you please clarify what you mean by 'abandons cache store operations'?
Does it mean that a read-through/write-through op is omitted, but the
public API method returns without an error? If it is so, then this is a
bug. If a public API method finishes with an exception when read-through is
omitted, then I think it is a correct behavior.
