Re: When Cache Metrics are switched on (statisticsEnabled = true) the empty cache events arrive to the client nodes
Hi Roman,
I suppose that we can resolve the ticket with 2.8 fix version if you
have no objections.

Hi Ivan,
Does it mean that the problem is gone and I should close the JIRA IGNITE-12445 ?

Re: When Cache Metrics are switched on (statisticsEnabled = true) the empty cache events arrive to the client nodes
Hi Roman,
Thank you for reporting this! I looked into and on my machine I was
able to receive events on client-handler node but exception occurred
in the local listener! In a following line:
System.out.println("Received event [evt=" + evt.name() + ",
cacheName=" + evt.cacheName() + ", key=" + evt.key().toString());
This indeed looks like a weird bug. Event appears broken after
deserialization on a listener side after it is received from a server.

[jira] [Created] (IGNITE-12445) When Cache Metrics are switched on (statisticsEnabled = true) the empty cache events arrive to the client nodes
Roman Koriakov created IGNITE-12445:
---
Summary: When Cache Metrics are switched on (statisticsEnabled =
true) the empty cache events arrive to the client nodes
Key: IGNITE-12445
URL: https://issues.apache.org/jira/browse/IGNITE-12445
Project: Ignite
Issue Type: Bug
Components: general
Affects Versions: 2.7.6
Environment: OS Name Microsoft Windows 10 Pro
java version "1.8.0_231"
java version OpenJDK 64-Bit Server VM 11+28
Reporter: Roman Koriakov
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 ({color:#172b4d}Sometimes {color}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.
{color:#cc7832}catch {color}(Exception e) {
{color:#cc7832}if
{color}(!{color:#9876aa}cctx{color}.cacheObjectContext().kernalContext().cacheObjects().isBinaryEnabled({color:#9876aa}cctx{color}.config()))
{color:#cc7832}throw {color}e{color:#cc7832};{color}{color:#cc7832} if
{color}({color:#9876aa}log{color}.isDebugEnabled())
{color:#9876aa}log{color}.debug({color:#6a8759}"Failed to unmarshall
cache object value for the event notification: " {color}+
e){color:#cc7832};{color}{color:#cc7832} {color}

When Cache Metrics are switched on (statisticsEnabled = true) the empty cache events arrive to the client nodes
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?
