Anton,
thanks for quick response. Not sure if I'm setting wrong expectations.
Just tried sql query and that exhibited the same behavior. Created a pull
request with a test: https://github.com/novicr/ignite/pull/3.
The test goes through the following steps:
1. creates a 4 node cluster with
Hello Gianluca,
There might be a several reasons for this slowdown. Could you please provide
a couple of consecutive thread dumps when node startup hangs and a node log?
If it is possible, could you do a restart with -DIGNITE_QUIET=false -ea JVM
flags?
Regards,
Anton

You are right, this log is JVM log. Let me post some messages below if it can
be of any help.
The cluster had less than 1000 records at the time of event. Do you still
think eviction can help there?

The file I've attached contains JVM logs. Let me post it below.
About eviction - the cluster didn't have too many records, less than 1000.
Do you still think eviction could be useful here?

Hello Roman,
Correct me if I'm mistaken, you are talking about SQL queries. That was
fixed under https://issues.apache.org/jira/browse/IGNITE-8927, primary
ticket is https://issues.apache.org/jira/browse/IGNITE-8834, will be
delivered in 2.7 release.

Hello!
I have spent some time tinkering with your case, and I think that an issue
exists.
If you have a partitioned cache with non-local continuous query, it works.

As long as you use IN statement there is no need in additional id > 0

Please, check the file you attached, it doesn't contain any logs.
Persistence will help to save data and prevent running out of memory.
Another option is to set an eviction policy:

When you deploy the service, it serializes the object of this service and
puts it to the internal cache. At the moment when it should be redeployed,
it will take this object from the cache and deserialize it.
So, if after change your object still can be deserialized using the new
version of the

There is difficult transaction in my system, requires to put about 50 objects

have difficult internal structure with object and collection fileds.

Yes we have more caches, but they are smaller, and the number of incoming

Hello!
You cannot avoid deserialization since data is stored in off-heap in
serialized form and also perhaps sent over network.
If you have a lot of different types, using HashMap will be preferred (with
primitive keys/values).
You could also try storing byte[] values to have precise control
Hello!
I suggest that you check those possibilities out:
Does performance increase dramatically if you need it on 10% of data, i.e.,
~1 million records?
Does something change when you have only one client connected?
Note that I was running this example on a single node so it should not be
hard
I use persistent storage but not so many caches and so far no problems,
I have 20 caches with around a total of 800.000 entries, each entry is
small (<100 bytes), while testing I update around 5000-1 entries per
second, restarts do take some time but never more than 2 minutes or so,
so far
Hi!
Is there some meta data storage overhead for binary object "types" ? I
need a cache where the value is pretty much a small key value store
(5-10 keys and values, all strings, every value different) and with that
few values maybe just two arrays with keys and values or a hash map, but

Hi,
Ignite provides 2 way for configuring indices: queryEntity and annotation
based.
Seems, you either forget to setIndesTypes or tring mix both of these
approaches.
