Aleksey Plekhanov commented on IGNITE-15317:
--------------------------------------------
[~qvad], as far as I understand you create a cache in thin client only by cache
name ({{(.getOrCreateCache conn cache-name)}}) while in thick client it's
created by cache configuration ({{(.getOrCreateCache conn cache-config)}}). If
you specify only cache name, then an {{ATOMIC}} cache will be created.
> Cache.put/get Jepsen Elle test failed for Java Thin Client

> Key: IGNITE-15317
> URL: https://issues.apache.org/jira/browse/IGNITE-15317
> Project: Ignite
> Issue Type: Bug
> Components: thin client
> Affects Versions: 2.10
> Reporter: Dmitry Sherstobitov
> Priority: Critical
>
> I've created simple jepsen elle test with for basic functionality
> cache.get/put. There is 2 versions of clients: one for thick client and other
> for thin client. Invoke code is exactly the same.
> Test passed for thick client and failed for thin client. Note that this issue
> is reproducible even with noop nemesis algorithm.
> {code:java}
> (reduce
> (fn [txn' [f k v :as micro-op]]
> (case f
> :r (let [value (read-value cache k)]
> (conj txn' [f k value]))
> :w (do
> (let [contain-key (.containsKey cache k)
> value (read-value cache k)]
> (if (or (not contain-key) (and contain-key (<
> value v)))
> (.put cache k v)
> (vreset! tx-state false))) ; bye functional
> programming, we are saving state here to fail tx later
> (conj txn' micro-op))))
> {code}
> GitHub repo with jepsen code: https://github.com/qvad/jepsen (see ignite
> folder there, there is also small guide how to launch hyper-v VM and run test
> there)
> Elle reports following anomalies (:anomaly-types (:G1a :G1b :internal)),
> which is aborted reads and intermediate reads.
