Hi Community,
I’d like to ask you about the following behavior of Apache Ignite:
If we want to react on some PUT or READ cache operations first of all we need
to turn on the appropriate cache events on the server node and catch those
events on the client nodes using remote approach with two listeners. It works
well until we switch on statisticsEnabled on the server node, it will lead to
the situation when we get empty CacheEvent objects.
The example that demonstrates this issue is in the attachments. This example is
consists of three nodes: 1 server node with cache and 2 clients. One client
is filling the cache and the second one is listening PUT operations. When we
turn on Cache Metrics on the server node:
cacheConfig.setStatisticsEnabled(true); in EventServerCache.java we get empty
events (Sometimes CacheEvent objects with null fields. Sometimes there are no
events at all)
My suppose is there is some Exception in GridCacheEventManager.addEvent() when
Cache Metrics is turned on.
catch (Exception e) {
if
(!cctx.cacheObjectContext().kernalContext().cacheObjects().isBinaryEnabled(cctx.config()))
throw e; if (log.isDebugEnabled())
log.debug("Failed to unmarshall cache object value for the event
notification: " + e);
if (!forceKeepBinary)
LT.warn(log, "Failed to unmarshall cache object value for the event
notification " +
"(all further notifications will keep binary object format).");
forceKeepBinary = true;
key0 = cctx.cacheObjectContext().unwrapBinaryIfNeeded(key, true, false);
val0 = cctx.cacheObjectContext().unwrapBinaryIfNeeded(newVal, true, false);
oldVal0 = cctx.cacheObjectContext().unwrapBinaryIfNeeded(oldVal, true, false);
}
Can public this point in JIRA?

Hello!
You will need to register on https://issues.apache.org/jira/ first.
Please tell me when you do.
