Galder Zamarreño commented on ISPN-3293:
----------------------------------------

Saw this as I was reviewing https://github.com/infinispan/infinispan/pull/2341. Not sure why the synchronous put happens (Dan?), but we should probably at least document it. Tristan?

> I have a cluster of 2 nodes with the following configuration:
> {code:xml}
> <replicated-cache name="memcachedCache"
>     start="EAGER"
>     mode="ASYNC"
>     batching="false"                    
>     queue-size="1000"
>     queue-flush-interval="15000">
> </replicated-cache>
> {code} 
> The following code (MemcachedHelper is a memcached client)
> {code}
> mc1 = new MemcachedHelper(server1.getMemcachedEndpoint().getInetAddress().getHostName(), server1.getMemcachedEndpoint().getPort());
> mc2 = new MemcachedHelper(server2.getMemcachedEndpoint().getInetAddress().getHostName(), server2.getMemcachedEndpoint().getPort());
> mc1.set("key1", "value1");
> assertTrue(null != mc1.get("key1"));
> assertTrue(null == mc2.get("key1"));
> {code}
> fails on the 2nd assert, because the entry is retrieved.
> According to logs (attached), the replication queue is correctly flushed after 15 seconds with 1 element (and happens after the gets).
> Works correctly with hotrod (entry is replicated only after the flush happens).
