Yes,
Tables created dynamically in caches that use a persistent data region
will be stored to disk.
You can try by enabling persistence for the default data region.
Create a test table, populate w/data, shutdown ignite then restart, data
should be there.
Thanks, Alex

We're using native persistence for each of them. Does dynamic cache
creation work for tables?
Is it possible to create tables dynamically that have persistence?

Then how to create shared file system or is there any way to access/modify
file written by one node in cluster by other node ??

I have no idea, I recommend collecting a heap dump and analyzing it to

Our current optimizer is not very smart. If you found an USE INDEX which
allows your query to run sufficiently fast, my recommendation is to just
use it.

We do not recommend developing new IGFS applications because we are

Hello!
Ignite has optional on-heap tier and also optional disk tier (Native
Persistence will offload data there as RAM is exhausted).
I wonder if that's enough for your use case.

Hi Ilya,
Thank you very much. I suspect (1) is the missing piece of information I was
looking for. I'll add it when I get a chance and will report back.
Thanks again,

Hi igniters,
I'm using a client node in C++ to lanch several compute on a cluster, and
it's working quite well, but when I try to close the node with every king
of Ignition::Stop/StopAll(true/false), my client remain freezed.
I'm using the 2.7.6. Do you have any suggestions?
Thanks,

Hi Ilya,
That certainly makes sense, but I'm not totally sure how to act on that
information yet. A couple questions:
1.) Given the configuration file I posted (which is basically the same on each
node in the cluster, save that the IP addresses of the nodes to discover are
different),

Your node has never finished joining to cluster nor was able to
self-discover to form a cluster of its own, as evident by:

What are you trying to achieve? You can do read/write through with an external
third-party database, you can use Ignite’s transactional persistence, both of
which allow you to have different tiers with varied speeds/volumes of data.

I am looking for tiering facility. If Ignite support then send some links or
info.
Thanks in advance.
