Is Apache ignite support tiering or it only support caching??
I am looking for tiering facility. If Ignite support then send some links or
info.
Thanks in advance.

Ignite supports persistence to disk. It’s configured using data regions. So you could have one data region that’s entirely in memory and another that’s on disk. We don’t call them “tiers” but that’s effectively what they allow.

I am new to ignite. I think in data regions we are specifying how much size
we want to allocate and it is from RAM. Yaa,I agree that we can de slice or
dice memory but how to specify other tier than RAM. What if I want to
allocate 1gb data region from dev/sda or any available device ??

Please check out this documentation about data regions configuration. With
the regions, you can slice and dice your available memory space and enable
persistence tier per region.

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.

I want to different tier like DRAM, available devices as a tier. How to
specify such tier option.

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.
