Hi all,
Here's my case.
The swapEnabled is true.
I have 120 pieces of data that 100 pieces are stored in memory and the other 20
pieces in hard disk.
Will the rest 10 pieces be moved to memory if I delete all data in memory and
10 pieces in hard disk?

I find the minimal scheduling time unit this scheduler supported is 1 minute.
But I need a scheduling time unit less than 1 minute .
Is there a way to make it happen?

Hi,
I have about 17GB data needs to be loaded into ignite.
Every time I destory the cache and create the cache with the same name, the
memory increases 17GB.
It seems the off-heap memory not released.
I find ignite can release off-heap memory when grid stopped.
I'd like to know if ignite can
Hi all,
I have read the article about jvm and system tuning
(https://apacheignite.readme.io/docs/jvm-and-system-tuning#section-detailed-garbage-collection-stats).
I found it mainly focus on physical machines.
But I use virtual machines. Is there any optimization for the virtual machine?

Hi Val,
Thanks a lot for your reply.
For the third question, I have a case.
I buckup a cache in non-heap memory with some updates eveyday. When it's
finished, I destory the former cache. But system memory is used more and more.
Here's a url.

Hi all,
I have several questions about ignite 1.6.0's cache.
1. When does ignite free the non-heap memory? I found a system.gc in source
code, is it?
2. How can I check the data in non-heap memory with just ignite itself?
3. Are there any bugs about ignite cannot release non-heap memory cor
Hi all,
I have a strange case.
First, I use LoadCache to load 6,000,000 data into a cache named eqt, it takes
about ten minutes.
Second, continuously query eqt cache.
Third, use LoadCache to load another 6,000,000 data into a cache named
eqt_temp.
Forth, continuously query eqt_temp cache an

All machines are in the same computer room.
I run my only one client code on one of my servers.
In addition, I use ignite 1.6 and execute sql query in filter.

I'm trying to get faster reads. Write is good for now.
Here's my read example. It's just testing environment.
I have two caches, Cache1 and Cache2. And preload 45,000 tips in Cache1. Put
1,000,000 tips into Cache2 to trigger continuous query in Cache1. After the
end, cons
Hi,
I demand both read and write operations, so I chose partitioned mode cache.
When I increased my cluster by one node, I got slower reads.
Is there any way to make it faster?
Er...
In my opinion, readthrough synchronizes data from hbase to ignite cache. Even
though readthrough doesn't get any data from hbase, it also synchronizes data.
As a result, nullpointerexception comes out.
As I mentioned before, I use hbase without ignite to execute that line,
console will
hbasetest.HbaseLoadCacheStore.load(HbaseLoadCacheStore.java:121), which is not
an Ignite class.
Is this your code? Can you check what is null in this class on line 121?

Hi??
I've already read the development manul about these three methods. And it says
that putall is inefficient when cluster loads a large nember of data.
Here comes my problems.
What are the advantages of localcache and streamer in big data?
Are there any mesures to ensure data is not lost?
Thanks a lot for the answer.
But here's a new question coming from it.
What's ignite's mechanisms for executing distributed queries?
Mechanisms for distributed queries used in local mode is clear to know, how
about mechanisms used in partitioned mode and replicate mode?

Hi,

I don't think that the progress is just the same as solr cause ignite doesn't

Is there anything similar? If every node in ignite cluster has two
