Concept Question about Ignite
Hello,
I am new to Ignite and have a few questions.
If I have two process running the following code:
Process 1:
Ignite grid = Ignition::Start(cfg);
Cache<int, std::string> cache = grid.GetOrCreateCache<int,
std::string>("myCache");
Process 2:
Ignite grid = Ignition::Start(cfg);
Cache<int, std::string> cache = grid.GetCache<int,
std::string>("myCache");
Will Cache be duplicated to the grid in process 2?
Thanks,
Anthony

Hi Igor,
Do you know if we have benchmarks for this?
Thanks,
Evgenii

Evgenii ,
Have you ever happen to measure that, for cross-language marshalling, the
performance between JNI and IGNITE?

Hello Evgenii,
I foud that the link for More information on CacheConfiguration can be
found here: is missing, could you please resend it to me?
Also,is there a way to find out which setting is the fastest and minimal
overhead?
Thanks,
Anthony

Hi,
If these nodes are combined into one cluster, then it will be the same
cache. By default, it will be Partitioned cache without backups and both
nodes will have part of the data. If you want to replicate data fully, you
can set backups to 1 or create cache as Replicated instead of Partitioned.
More information on CacheConfiguration can be found here:
