missing website info

dsetrakyan
I have been going through the Ignite website today, and I have noticed that
nowhere on the website we mention various modes on how Ignite native
persistence can be used:

- no disk, data is in memory-only (potentially over a 3rd-party database)
- disk is a copy of the memory (only for recovery purposes)
- disk is a data storage with memory used as a performant caching layer

I believe we should put it in a table and explain it somewhere (homepage?).

Denis, Prachi, what do you think?

Dmitry,

I can also suggest to refresh on web-site "Contribute to Apache Ignite" [1]
page by the new main tickets to pickup. e.g. we have a lot of interesting
tasks with IEP-4 implementaion.
I think this will help newcomers to get one's hand in Ignite project.

Thoughts?

Hi Dmitriy

Could you explain what is the difference between:
- disk is a copy of the memory (only for recovery purposes)
- disk is a data storage with memory used as a performant caching layer

I assume it is all about DataRegionConfiguration.setPersistenceEnabled and
there is no other options I can imagine.

Could you refer to options for cases 2 & 3 user should enable to cover
these 2 cases.

Sincerely,
Dmitriy Pavlov

Hi Maxim,

I had similar idea to provide list of "Needed Contributions" from point of
view of community/PMCs.

 Not all issues have equal pripority for product and it is easier to find
reviewer for such wanted issues, than for low priority improvement.

Sincerely,
Dmitriy Pavlov

Dmitriy,

Presently this information is scattered and presented under sections named
differently. Agree with the format proposed by you.
https://issues.apache.org/jira/browse/IGNITE-8455

In addition, we should cover another mode which is indexes in RAM and data
on disk to get a better technical cost of ownership of Ignite's cluster. I
heard it's already possible to set up this kind of configuration.

Agree, but we do not have this mode yet. When we do, we should definitely
cover it.
