I assume that Vladimir mention this mesurements:
https://shipilev.net/blog/2014/nanotrusting-nanotime/
can we simple measure with JMH x86 and arm our realization vs system call?
As Dmitry P mentioned System.currentTimeMillis() is JVM intrinsic.
Moreover, there is a daemon thread that updates the
Guys, hope i can add one more example here.
Ones we use IgniteAtomicSequence, after topology changes some assertions
can be catched due to default AtomicConfiguration
i.e.
public static final int DFLT_BACKUPS = 0;
public static final CacheMode DFLT_CACHE_MODE = PARTITIONED;

hi, Igniters.
I have a question about compute broadcast behavior with peer class loading
enabled.
Look, my test schema was like:
1-jvm PureServerApp - pure server GG node.
2-jvm FirstComputeRunner - first compute runner node.
3-jvm SecondComputeRunner - second compute runner node.

there,
can anyone hint me - what kind of changes are applicable here:
1. client node need to send "cacheMetrics" too, through

Hello Igniters,
There is fresh doc about mongodb analysis with jepsen tool:
https://jepsen.io/analyses/mongodb-3-4-0-rc3
Looks like mongo soon would be production ready database )
And what do you think about the same analysis for ignite?
I have no deal with jepsen but has a lot of positive feed
postgres has the different viewpoint, i hope.

Hi,
That’s true that the utility/testing framework needs to be as flexible
as possible. If the community can’t reuse an

However, as for SWIG. Do you think it’s feasible to implement on top of
Ignite.C++ client which is tightly coupled with JVM?

Hi all.

(http://www.swig.org) as automatic wrapper, generate clients for absence
scripting languages.
What do you think about this c
